Don’t fret, it’s getting cooler: August isn’t as persistently blazing as July

While the “dog days” of summer continue well into August by most definitions, temperatures are on the decline with the year’s hottest month of July largely behind us. Sure, these cool facts might not always be apparent every single day, but by August’s end the idea that refreshing times are ahead is often starting to become noticeable.

Heavy downpours of July 10: flooding in Bloomingdale, D.C.

A weak area of low pressure passed over the D.C. area yesterday evening. As the atmosphere was flush with moisture, a very localized, but intense band of thundershowers developed between central Fairfax county and north central Prince George’s county. Torrential rain accompanied the thundershowers - with the heaviest rain falling in the heart of the District of Columbia.

June is off to a cool start in Washington, D.C. and much of the Northeast this year. As forecast last week, a big dip in the jet stream has released cold air out of Canada. Today will be Washington, D.C.’s third consecutive day with highs only in the spring-like 70s.

After the warmest and top ten driest March on record, April brought back a sense of weather normalcy. While relatively warm (1.5F warmer than normal) and dry (1.1” drier than normal), the month didn’t produce many extremes. But compared to March, April offered more weather variety: with more cooler-than-normal days and at least a few rainy/cloudy days.

Freezing temperatures may again visit the far northern and western reaches of our region tonight and even creep close to the beltway Friday night. You might be wondering when is the risk of freezing temperatures finally over in the region? In some places, it won’t be until some time in May.

More than 7,700 daily record high temperatures were set (or tied, compared to just 287 record lows), in some cases by mind blowing margins and over multiple days. It’s no surprise that, after data were crunched, scores of cities easily set March monthly records for warmth.

Lack of snow and recent dryness cause for concern for Washington D.C. summer drought?

Even with some — generally underachieving — rains last weekend and Wednesday, much of the area remains abnormally dry. The new U.S. Drought Monitor update, released yesterday, even shows the beginnings of a short-term drought to the south and east near the Maryland shore. Does the recent dry weather portend a drought this summer?

Capital Weather Gang officially retired Season 2 of the Snow Potential Index (SPI) last Friday, forcing disappointed snow lovers to come to terms with the remarkably warm winter of 2011-2012.

What is Washington, D.C.’s weather like in March? Breaking down norms and extremes

Meteorological spring starts with the first day of March, and the astronomical version comes along in the final third of the month. It’s by no means one of D.C.’s warm months, but the signs of milder times to come are often significant. But, it can also still be chilly at times and even snow.

Poll: How would you grade this winter’s weather in Washington, D.C.?

It was the warmest meteorological winter (December through February) since the Great Depression, ranking third mildest on record. Snow? What snow? We’ve had 2” of it and never more than 0.6” in a single day! Assuming we don’t get any more snow by the end of April, it will also rank as 3rd least snowy on record.

Does D.C.’s warm winter mean a hot summer is to follow?

As we now know, meteorological winter (December through February) 2011-12 finished as the third warmest on record here in Washington, D.C.. Thinking back, warmth seems all too common around here, especially when one considers the last two summers were the hottest two on record. The fourth warmest February on record to close our toasty winter can’t be a good omen going into the warm season, can it?

February 4th warmest on record, meteorological winter 3rd warmest

February and the meteorological winter (spaning December through February) have just come to a close, but why do I feel like we are transitioning from autumn to spring right now? This has certainly been a winter in name only as we continue to draw sharp contrasts against the previous two colder-than-normal winters. So let’s look at how we stacked up in the final tallies...

Leap day weather: new rainfall records set at Dulles and BWI airports

Occurring only once every four years, weather records for February 29 are necessarily limited. For example, the number of leap days on record at Dulles airport is just 13, since observations began there in 1963. Thus, it’s not surprising that today’s old rainfall record of 0.51” from 1968 was easily passed today. The airport has received 0.99” so far.

As cherry blossoms promise an early bloom, some pre-spring gardening tips

We are just beginning our most floriferous time of year. Of course, one of the main treats in Washington, D.C. will be the bloom of the region’s cherry blossoms. This is the 100th anniversary of these trees coming to the Tidal Basin so it should be quite an event.

Toughest places to forecast weather: a match for Washington D.C.?

From trying to nail down the rain-snow line in winter to predicting the timing and location of pop-up thunderstorms in summer, the fickle nature of D.C.’s weather presents problems for even the most seasoned forecasters. What forecast challenges do other regions contend with? Are they as difficult as Washington, D.C.’s?

Whether it’s extreme heat, extreme cold, blizzards, hurricanes, severe thunderstorms, tornadoes, droughts, floods, or just plain high winds, Washington experiences an incredible range of weather conditions. But is D.C. weather really more difficult to forecast than elsewhere or is that just an urban myth, perpetuated by mean-spirited cynics?

D.C.’s longer daylight hours mean spring really is just around the corner

A balmy 60-degree day in early January might feel like spring, but when darkness falls around 5 p.m., we’re inevitably reminded that it is still winter. Now, at least, we’ve got the longer daylight and higher sun angle to accompany our spring-like temperatures, even if they are (once again) several degrees above average.

March outlook: Warmer than average, low snow chances

The warmer than normal winter is expected to continue into at least the first two weeks of March and will probably last through the month. That doesn’t mean there won’t be quick shots of colder than normal weather but that there is unlikely to be sustained cold. And snowstorms will still probably be hard to come by.

On average, precipitation remains at a cold-season nadir. Still, the month has provided many memorable snowstorms.

Only about 15 percent of all winters in D.C. have recorded as little or less snow than we’ve seen this year. We’re now running almost 7” below normal season to date and it’s leaving some wondering what our chances are to break even. A look at past occurrences and the historical record might offer a few clues.

Our gardens in a mild winter: the good, bad and beautiful

Let me say right off the bat, my garden does not look much different this year than any other year, except it isn’t buried under a snow drift! Why is that? Many of our plants evolved over the centuries to be more in tune with the dependable daylight hours than the more erratic temperature regime.

Winter activities to keep a gardener occupied until spring

Certainly the last month has been a kind one to the late season garden with plenty of rain and relatively mild temperatures. Pansies are looking pretty good out there along with the cabbages and kales. It doesn’t look like any real cold blasts are coming any time soon either so more time to enjoy the hardy garden denizens. Now don’t get me wrong, I enjoy some time off from the garden. But inevitably I find myself drawn to it. So what is a gardener to do this time of year?

But if you’re like me and usually celebrate Turkey Day in the D.C. metro area, you probably recall some years offering typical November weather and others that were nearly warm enough to consider moving the meal outside. At the other extreme, we’ve even had a bit of snow to accompany the turkey on a few rare occasions

As November progresses, it usually becomes unmistakable that winter is around the corner. The days are short and the landscape begins to turn barren. Cold intrusions become more of a norm than a rarity as well, and on some occasions that cold air combines with moisture to produce an early-season snowfall.

Appreciating fall, and preparing the winter garden to shine

Depending where you are in the area, the leaves are at the peak of their brilliance or falling fast! Despite the dry spells and deluges this summer, most of the colors came on pretty nicely. It is an annual delight to see those brilliant yellows of the gingko trees in Georgetown, russet beauty of the oak trees in Takoma Park and glowing oranges of the maple trees that line many of our streets throughout the area. But it is now time to focus on some of the other preparations for the winter season.

Do October and November snow signal a snowy winter?

OK, so we had some snow in parts of our area last month (just a trace at Reagan National and .6 of an inch at Dulles), now that it’s November, we could have some more. Time will tell. (I don’t do the forecasting on this blog.) But what does October snow mean, if anything, for the rest of the winter as a whole? Curiosity got the best of me and, although it’s been done many times before, I decided to do some of my own research.

The weather has been pretty accommodating for gardeners in the past week, given the nice weekends. Moisture has been plentiful as can be seen in the map of the past two week’s rains. I have been busy getting my spots all plotted for those bushels of bulbs that have just arrived. The dormant season is approaching, but now is far from the dormant time for the gardener, so today let’s talk about getting the garden ready for winter.

When should the Washington, D.C. area expect to see its first freeze of the cold season?

As we head through fall, the first freeze of the season is assured in only a matter of time. But, when is that time? Well, it depends on where in the area you are located. For many places, especially north and west of downtown D.C., a freeze can be expected before October is out. As you head into lower elevations to the south and east of D.C., or those close to warmer water, the wait often goes through November. Some years, spots even make it to December without one!

About 50 tornadoes in Virginia in 2011, second most on record

After 7 twisters touched down in Virginia last week, the 2011 count has risen to about 50*, second most on record (since 1950) for the state. 2011 ranks only behind 2004, when 87 tornadoes touched down, and just ahead of 2008, when there were 39

Grading our summer outlook

Hopefully the pleasant autumn weather of late has helped purge another brutal summer from your memory.  Unfortunately, we are here to remind you one last time before we can get on with the business of looking ahead to winter.  Here is a quick recap of our summer outlook. Although we did predict all three summer months to be warmer than normal, there will be no back patting.  With the second hottest summer on record, rivaling 2010, we missed the mark.

Musings on a fall gardening weekend...

For once, the past two weeks have been pretty uneventful. Rains have been a little light but nothing bad, save for a few heavy showers this morning. Temperatures have been near normal. Why we even have the good weather coming on the weekends now! This brings me to the week’s discussion: musings while working in the garden last weekend.

Is our current weather “normal,” or not?

With the recent release of the new climate “normals,” the perennial question rears its head, as it always seems to do every 10 years, if not sooner: “What does normal weather really mean?” Is it the weather to be expected or is it just an average of weather over the past 30 years?

What is Washington, D.C.’s weather like in October? Breaking down norms and extremes

October and abundant sunshine often go hand in hand in the D.C. area, but the pattern is still a bit lazy compared to winter, so rains can come in heavy bouts over several days. When it comes to temperatures, averages are about as good as they get all year for some serious outdoor enjoyment! The shift toward colder weather is clearly evident though.

Say goodbye to sunless September 2011

The cloud cover quantity in September was quite impressive as only TWO days qualified as mostly sunny (30% or less cloud cover). At Reagan Washington National Airport (DCA), it rained on 60% of the days. Those rainy days piled up a 5.12” surplus of rain compared to normal (8.84” total!). Historically, that is the fifth wettest September on record. Despite a very wet month, it was still less than half of the record for the wettest September (a super-saturated September 1934’s 17.45”)!

On Thursday, the count for mold spores in Washington, D.C. rose to 47,483 spores per cubic meter of air. That concentration was the highest in the U.S. Army Centralized Allergen Extract Lab’s ten year record for September according to Susan Kosisky, a microbiologist at the Walter Reed Army Medical Center lab.

Fall is here, but for gardens, time to think about next summer...

If you feel like our climate has shifted to rain forest, you are not alone. The damp mild weather is not a novelty here but the persistence has been. However, for those of us close to D.C., would you believe that over the past two weeks (prior to last night), our rainfall has been nearly an inch below normal? There is probably no need to run for the sprinkler as temperatures have been mild and humidity levels high. Last time we spoke it was to prepare for spring bulb planting. Today, we go even farther into the future and think about summer bulbs.

Autumnal equinox marks the official start of fall Friday morning

While meteorological fall already began three weeks ago, the autumnal equinox occurs Friday at 5:04 a.m. (EDT), signaling the official start of fall in the Northern Hemisphere. Besides ushering in a new season, the fall equinox marks the time at which the sun shines directly overhead at the equator, which results in nearly equal periods of daylight and darkness at all latitudes. Until the winter solstice in December, the sun will continue its southward migration towards the Tropic of Capricorn, bringing us increasingly shorter days and a lower sun angle in the months ahead.

Worst D.C. September weather in memory?

”Wake me up when September ends”: Although that Green Day lyric is so 2005, it probably has entered more than a few minds during this depressingly dim September. So far this month, we’ve had at least a trace of precipitation on 12 out of 20 days. And dismally, we’ve had only four days with more than 50% sunshine.

Are you ready for fall? Is there any summer weather left?

The onset of fall weather came abruptly last night. After more than 90 days when lows failed to even reach the 50s in D.C., we plummeted all the way into the 40s. And this afternoon’s temperatures are stuggling to reach the mid-60s, the coolest since early May.

Fall is here, but for gardens, time to think about Spring!

Hopefully everyone’s garden survived the deluge from tropical storm Lee’s remnants. We were stuck between a rock and a hard place with all of Lee’s voluminous moisture funneling up from the south and Hurricane Katia offshore, blocking it from progressing out of the area. While the onslaught of rain was one way to break a drought for good, it was probably not the best way. Fortunately, we are drying out nicely now as it is about time for one of my favorite garden endeavors, bulb planting.

What is Washington, D.C.’s weather like in September? Breaking down norms and extremes

September may often be cited as the beginning of the “nice weather season” in Washington, D.C. Summertime heat and humidity are on the wane, and glorious sunny days are only sometimes stopped in their tracks by (often tropical and sometimes significant) rain events. As the month progresses, those overnight lows start getting back into the light jacket type of territory. Can talk of snow be far off?

There are certain weather events that get etched into our memories because of their impact. This week’s flooding rains are sure to end up in that category for many in the Washington region. While the rain event is not completely over, some early comparisons can be made by taking a look at the historical record in the area.

Washington, D.C. flooding: What’s behind the rain train?

Relentless and punishing: words used to describe the heat in June and July can now describe the onslaught of torrential showers and thunderstorms since late Sunday. East of D.C., 6-10 inches of rain over the last four days has been common and widespread flooding has occurred. An uncommon combination of moisture streams has converged to make this prolific rain-producer possible.

Rainy week: what’s the cause and how much?

The rain poured down fast and furiously last night producing 1-2” of rain across the immediate metro region, and up to 2-4” to the west and southwest. The rain, which prompted several flash flood warnings, was just the first of several waves of rainfall likely over the next few days. By the end of the work week, cumulative rainfall totals may reach 3-6” in the immediate metro region, with 4-8” towards the mountains. With in both of these areas, locally higher amounts cannot be ruled out.

Cleaning up the garden after sloppy hurricane Irene!

I hope everyone is recovering from the wrath of Irene. Looking at some of those pictures of flooding in wetter areas up north, I would say our drought was our salvation. Having dry soils helped to keep most trees well rooted and safe from toppling, which would not have been the case if the ground had already been soaked. So I guess we can count our blessings in many ways.

After manageably warm August, second hottest summer on record in Washington, D.C.

After our all-time hottest month on record in July, it was certainly a relief to see a change in the jet stream pattern over the mid-Atlantic by mid-to-late August. The big hot heat dome that dominated June and July resided primarily over the South Central U.S. in August (consider Houston’s pain- only one day of the entire month saw a high temperature below 100 degrees!). However, a cooler August did not allow us to escape the status as the second hottest summer on record- behind only last year (2010).

Dissecting the daily digit: History, seasonal averages, temperature trends, and other trivia

If you’re an avid reader of Capital Weather Gang’s morning forecasts, you have no doubt noticed that little box with the green number and a snippet of commentary, better known as the “Daily Digit.” We announce it on Facebook and Twitter the night beforehand. And depending on what kind of weather is your cup of tea on any given day, you may find our assigned digit to be too generous, too harsh, or sometimes just right. What is the daily digit, and how did it come about? For lack of a better definition, we define the digit as a somewhat subjective rating of the day’s weather, on a scale of 0 to 10. It debuted on December 16, 2009, just three days before D.C.’s biggest December snowfall on record. Since then it has become an integral part of our morning forecasts – so much so that many of you have asked questions about the history of this arbitrary number. Today we’ll look at some overall trends and other interesting trivia in the daily digit’s now 20-month history.

Recap: Hurricane Irene’s rain and wind in Washington, D.C.

Around the Washington, D.C. metro region, Irene behaved largely as predicted (at least by the Capital Weather Gang), raking the I-95 corridor and points east with wind and rain, with steadily diminishing impacts as you headed west towards Loudoun and Frederick county.

Late arriving Sunday rains produce wide range of totals through D.C. metro region

When the heavy rain finally arrived Sunday evening, it fell fast and furious. But, in some spots, it was pretty much a no show. Amounts were highly variable ranging from as little as 0.1” west and southwest of the District to almost 3” in portions of Montgomery and northeast Prince George’s county. The locations with the highest totals were subject to some extreme rainfall rates as well as an onslaught of lightning.

There is no disputing D.C. summer climate has warmed markedly since record-keeping began in the late 1800s. There is an overall warming trend of about 3 degrees F per century - slightly greater at night and lower during the day. But what one might dispute is the cause.

Yeah, it’s still summer but we're used to it by the time August rolls around, right? Even though temperature averages are on their way down, August provides just a bit less in the way of heat than July but considerably more than June. And while it holds several rainfall records, recent Augusts seem a bit dry.

Will August be as hot as July in Washington, D.C.?

After a record hot July, should Washingtonians be dreading what’s to come in August? The good news is that August is usually cooler than July. The average temperature in July is 79.8 compared to 78.1 in August. But it can still be scorching. Take, for example, August 1980 which set monthly records for both average temperature (82.8 degrees) and the number of 90+ degree days (22). That made August of 80 only slightly less sweltering than July 2011, with an average temp of 84.5 and 25 90+ days

July 2011: The hottest month in Washington, D.C. history

Congratulations D.C.-area readers. You have just experienced -- or tolerated, survived, and suffered -- the hottest month in recorded history. We did it last July too, but this time we soared just over another degree on average to achieve an incredibly toasty 84.5F at Washington Reagan National Airport. That’s 4.7 degrees hotter than the new 1981-2010 normal or 5.3 degrees hotter than the old 1971-2000 climatological baseline. Also, it is slightly hotter than a normal July for Houston, TX and slightly cooler than a normal July for Dallas, TX. It’s like we were living in a whole different part of the country.

Although the current heat wave, defined as any stretch of at least three consecutive days at or above 90, has reached its tenth day, the drop in humidity since yesterday has provided a reprieve of sorts. Smitten by today’s low humidity, Twitter follower @aimster215 wrote: “Today=best 90 ever.” But tonight, the sinister southerly wind returns, amping up the humidity Thursday through Saturday. How and hot and humid are we talking about? When will it end? And what’s causing the heat?

The heat has been terrible again today, though thankfully the humidity has been lower than yesterday so the heat index has been more forgiving - to around 110 compared to Friday’s 120+. D.C. has broken its record high for the date, with National Airport reaching a high of 102 at 3:38 p.m. So far, no storms have affected the immediate metro area, but a few strong storms could still develop in spots into this evening.

Reagan National’s heat index (factoring in humidity) reached 121 at 3 p.m., the highest known level since 122 on July 16, 1980.

Reagan National Airport dropped to a mere 83 degrees this morning, which - barring a cooling thunderstorm this evening - will set a new record high minimum temperature for the date. Even more impressive, that steamy 83-degree low (assuming it stands) would tie for the second warmest low all-time in Washington, D.C. (since records began in the late 1800s).

All gardeners have their horror stories when it comes to caterpillars in the garden devouring their hard work. My pansies disappeared thanks to all the munching. But to my surprise, a couple weeks later the garden was aflutter with hordes of fritillaries! I was hooked on finding other ways to help promote the caterpillars

Ever present D.C. rain split strikes for 5th time in 2011: what’s going on?

Last night’s thunderstorms, a few of which were severe, produced two bands of meaningful rain. One band tracked from Loudoun county through Montgomery county then into northern Montgomery and Anne Arundel counties. A second band tracked from Prince William county through Charles county. Both bands generally dropped about 0.25-0.5” of rain, with some isolated areas receiving 0.5-1”. In between these two bands, there was a noticeable gap in precipitation (where less than 0.1” fell), a recurring theme in 2011 begging the question: can this really just be a coincidence?

What is Washington, D.C.’s weather like in July? Breaking down norms and extremes

What can you say about July in Washington? It’s hot — in fact, it’s the hottest month of the year. Along with all that heat comes the near-daily risk of a pop-up thunderstorm in its usual hit-or-miss nature. But, the real story is the heat. The month tops all others in the 90-degree day category, averaging right around 14 such days.

Washington, D.C.’s new normals: warmer, less snowy

On July 1, NOAA released its new climate normals - which are used as a baseline for comparison with the current weather. The new climate normals span the period 1981-2010, whereas the old climate normals encompassed 1971-2000. In a post last week, I indicated that across the United States, the new climate normals were warmer than the old climate normals by about 0.5 degree F and that every state’s new normals had warmed. But what about Washington, D.C.? How have normals in the Nation’s Capitol changed? In short - they have also warmed - and a bit more than the national average. And interestingly, Washington, D.C.’s “normal” snowfall has dropped.

While not as hot at the record-shattering 2010, summer got off to a historically steamy start in Washington, D.C. Averaging more than four degrees above average, June 2011 tied with 1943 as the third hottest on record.

If the sneaky drought wasn’t enough to worry about, two of my most dependable pests have arrived right on cue in the garden: deer and Japanese beetles. Little did I know that some of my plantings are, as a good landscaping friend stated, “their version of filet mignon”.

When is it cool enough to shut off air conditioning?

Prior to yesterday, Washington, D.C. had six straight days of highs of 90 or higher. The temperature averaged ten degrees above normal during that span. Now, for at least a few days, the pattern has reversed, and temperatures are at or below average. In fact, Monday was the first below average day in the last 25. Of particular significance, the low the last two nights even at the urbanized Reagan National airport dipped to 65 and 64 (and to 61 and 53 at the more rural Dulles). The sudden shift in temperatures no doubt inspired many to open up their windows and shutoff the energy hogging air conditioning. But as comfortable temperatures are a matter of individual preference, I thought it would be interesting to pose the poll question, how cool is cool enough to allow mother nature to act as our cooling machine?

Washington D.C.’s record hot June day (tie): 102 degrees on 6/9/2011

Hot on the heels of Wednesday’s 99-degree record high at Reagan National Airport, Washington’s official observation station, the mercury spiked to 102 degrees Thursday, equaling the record for the date set in 1874. The 102-degree reading also matched the warmest temperature reached in the month of June since records started being kept in 1871.

What is Washington, D.C.’s weather like in June? Breaking down norms and extremes

Washingtonian’s know that by June the forecast often features heat and the chance of showers and storms. Just a few hints of the spring storm track remain, as summer really builds in. Days below 80 are increasingly rare, and nights are quite mild as well. While summer can be a little more on the boring side, June often provides some pre-Independence Day fireworks.

May ends hot, parched throughout

May 2011 closes out the meteorological springtime, and it ended on a very hot pre-summer note. The scorching 98F degree reading on May 31st was only one degree shy of the hottest temperature on record for the month (99F in 1991). We exceeded 90 degrees three times in May, which is about twice the normal (1.6 times). Our coldest reading of this month was a triplet of crisp, 46 degree lows back on May 4-6 (wow, that seems so long ago!). Overall, it was warmer and drier-than-normal for Washington, D.C. The precipitation story is probably a bigger concern with only about 1/3 of normal falling this past month. We could use a bit more rain here in June as I’m sure most of you have noticed recently.

Xeriscaping, it’s not just for the desert!

Xeriscaping. Sounds like something out of a sci-fi story. For me, it was always something I associated with rocks and cactus in the Arizona desert. Well, taking a course from the USDA a few years ago, I got a real awakening. It is not just about rock gardens, it can be adapted to any environment and can be every bit as inviting as the grandest English garden.

Fireflies flashing earlier as climate warms. Are we amidst a ‘renaissance of lightning bugs’?

Summer heat and humidity aren’t the only things to have arrived early in the D.C. area this year. Early last week, Capital Weather Gang commenters reported their first firefly spottings of the season. A warming climate has fireflies along with many other insects appearing earlier in the year than they used to. Recent trends also suggest a ‘renaissance’ of fireflies might be underway, with fireflies increasing not long after scientists feared they might be disappearing.

First we had the D.C. snow hole, now we have the D.C. dry tongue. For much of this week, we advertised flood watches, severe thunderstorm watches, heavy rainfall potential and so forth. The Nats even cancelled Tuesday’s game over the dire forecasts and only a few drops of rain fell. So what in the heck happened to all the rain? Answer: it artfully avoided us.

Perfect garden combo: beautiful and edible too!

How can you beat a garden that is both beautiful and edible?! A couple of herbs that do great at filling that bill are dill and fennel. I am a spice freak, so peppers like cayenne make a great addition to the hot spots in my garden. But by far my favorites are the edible flowers! In the spring there are the pansies and violas. Another great edible is squash blossoms.

Gardening in another dimension: “nanoclimate”

We all hear plenty about climate these days! Many of you know about microclimate too. One example is the urban heat island around D.C. which results in a longer frost free period; another is the infamous National Airport with its cooling river breezes (warming in winter). However, today I want to go even smaller scale. Let’s call it “nanoclimate”! It is something that nearly every gardener is going to run into at some time or another and the more you think about it the better off your plants are likely to be.

What is Washington, D.C.’s weather like in May? Breaking down norms and extremes

After April’s showers comes May’s flowers, right? Yes -- and more rain as well. While warmth typically continues to increase its grip on the region, there are still volatile mixes with winter’s remnant cold air masses to the north that create energetic storms with plenty of rain. In fact, May is typically D.C.’s wettest month of the year.

Washington D.C. March 2011 in review: slightly cold temps and wet

Our recently-ended March 2011 was a strange month with lots of temperature variability and some interesting precipitation events. From a temperature standpoint, the month was 5.6 degrees colder than last March and almost 1degree colder than the thirty-year fixed normal (1971-2000). Our warmest day was that excellent 80-degree high temperature on March 18 and our coolest day was the 41-degree high on March 3 followed by the 42F just last week on March 31.

Meteorological vs. astronomical winter

Now that we’re really done with winter (but not necessarily winter-type weather)--both meteorologically (December 1-February 28) and astronomically (December 21-March 20)--I thought I’d compare the two for the 2010-11 winter season, focusing mainly on temperatures. Bear in mind, however, that in the future, when most statistics are gathered, they will refer to the meteorological season, the official standard of the National Weather Service (NWS) as well as some other countries such as Australia and Brazil.

I don’t know about you, but I thought that this past (meteorological) winter, although not particularly snowy around here, was brutally windy on many days, perhaps more so than in many years. But perceptions are often wrong, particular when it comes to the weather, so I decided to do a little research. Was I right or am I just getting older so that I can’t take those “hold-your-hat-down-days” any more?

In what is almost certainly summer's last hurrah, temperatures today head for the mid-to-upper 80s. The mercury should easily sail past Dulles Airport's record high of 78 from 2001. Reagan National's record of 90 from 1919, the latest its ever hit 90, probably won't be matched or exceeded. Likewise, BWI's record of 89 from 1954 is a reach.

Two more daily climate records around the area may be broken today. First...the daily record highest minimum temperature for Aug 11 at DCA [Reagan National] is 78 in 1988. The min temp earlier this morning only fell to 80. Therefore, if the temp does not drop below the 1988 reading by midnight EST...then the highest min temp record will be broken today. Also...the daily record high temperature at IAD (Dulles Airport) for Aug 11 is 96f in 1980. The forecast high temp for today at IAD is 97.

Normally, our weather is not so normal

A few weeks ago, some of you may remember my article, "Believe it or not, D.C.'s is a Climate to Relish," in which I argued that, despite our winter of record-setting snow, the D.C. area's climate -- the highs, the lows, the extremes and the normals -- is relatively tame compared to other parts of the country. As a postscript to that article, and in the wake of yet another period of notable weather (this time a stretch of summer heat in early April), I will now focus on the latter of those climate components -- the "normals."

What is the mid-Atlantic?

I've found that the term "mid-Atlantic states" is often confusing, even to long-time inhabitants. Several times this past winter, the National Weather Service referred to storms which would primarily impact the northern or the southern mid-Atlantic and I had to ask myself, "Where are we?"
