PM Update: A few showers possible into tomorrow, and turning much warmer

It was one of those days where clouds just did not want to budge thanks in part to a moist flow off the ocean. However, we’ve finally begun to see some breaks late this afternoon, and that trend should continue the rest of the daylight hours. Despite the clouds, temperatures have warmed to a range from the mid-60s to near 70. Milder air is inbound!

Tim McCarver isn’t crazy: the home run and global warming connection

Over the weekend, baseball announcer Tim McCarver became the source of ridicule when he blamed global warming as a reason for the increase in home run totals in recent years. But it was the criticism of McCarver rather than McCarver’s comment that was over the top.

Washington, D.C. dazzles at dusk and dark: District nights (VIDEO)

The beauty of Washington, D.C. is often most spectacular in the fiery hues of sunset and when our historic landmarks glow before a dramatic night sky. Multimedia artist Andrew Geraci masterfully captured a series of these moments in a brilliant compilation of time lapse photography.

Forecast: Mild Monday then flipping the switch to summerlike warmth

Seven of the last eight days have been cooler than average and we probably tack on another today. But then, in a blink of the eye, high temperatures surge up to around 80 Tuesday and stay at that level for most of the week. Accompanying the warmth, we run the risk of a few showers and thunderstorms, especially Tuesday into Wednesday, and perhaps over the weekend

Forecast: Weekend closes on a warmer, sunnier note

We’re in for a marked improvement today, as far as the weather is concerned, over yesterday’s cool and mostly gray conditions. Any showers exit early and the sun prevails by afternoon. Clouds try to make a comeback tomorrow, before a warm front ushers in some serious midweek warmth, along with the potential for showers and thunderstorms.

Forecast: Shower chances increase late today before fading early Sunday

On average, spring is kicking into gear by now most years. But there’s still a battle with cooler air here and there, and we’ll see that play out this weekend. Today’s temperatures are muted by clouds. That’s followed by a return of sunshine on Sunday which sends readings back upwards. First, some rain may fall, though probably not enough to have any meaningful impact on our prolonged dry spell.

PM Update: Frosty Friday night (colder suburbs) followed by chilly, unsettled weekend

Five of the last 6 days (including today) have been cooler than normal and we stay on the cool side through the weekend. The good news is that, after previous concerns about a lot of rain, the balance of the daylight hours Saturday and Sunday should be dry, though a showery stretch threatens intermittently late Saturday afternoon through Sunday morning.

Super tornado outbreak of April 27, 2011: one year anniversary

Forecast: Windy but sunny today, then a cool and unsettled weekend

After we struggle with today’s wind, we may miss the sunshine. Should you go running, want to garden, compete in an outdoor scavenger hunt this weekend, we need to keep an eye to the sky. Timing is still hard to pin down for weekend showers and possible thunder—but if you had to choose outdoor activity schedules, try to do them today, Sunday afternoon, or Monday. Allergy sufferers also note that I can’t report (yet) that rain will be enough to fully washout pollen.

What a day! Highs mainly in the upper 60s to near 70 are just about average for the high this time of year. A breeze from the west and northwest has been occasionally gusty, but nothing too problematic. If you did not get much chance to spend time outdoors earlier, the evening promises to deliver as well. Any rain should hold off until late tonight and into tomorrow.

Behind the present pause in global warming

Has global warming stopped since the turn of the millennium? Yes - if you examine the data in a vacuum. But has the warming pressure on the atmosphere from man-made greenhouse gases stopped? No - not at all. A closer look at the data bears that out.

Morning sunshine assisted temperatures in improving by a good 10 degrees today (compared to Monday) even as cold winds wrapped around our departing Nor’easter and afternoon clouds bubbled up. Tomorrow, we lose a lot of the wind and many of the clouds. The result: we add another 10 degrees returning temperatures to late April normalcy.

Nor’easter dumps up to two feet of snow, five inches of rain

The biggest late April Nor’easter since 1928 has winded down after producing a large swath or heavy rains near the mid-Atlantic and Northeast coast and deep, wet snow in the interior and high elevations. The storm has passed into Canada and all winter storm warnings and advisories have been cancelled.

Today’s weather is a slow, incremental improvement over yesterday’s blustery bounce back to February or March-like weather. However, we still run cooler-than-normal with highs near 60F instead of a normal near 70F. And breezy conditions offer a bit of a wind chill yet. While not nearly as cool, clouds and more rain chances return Thursday with more unsettled weather this weekend.

We’re on the cusp of hitting an average high of 70 degrees in D.C., though on a day like this it might be hard to believe! Afternoon temperatures ranging from the mid-40s to near 50 are still a bit of a shock to the system after all the warmth we saw this winter and last week. The good news is that after tonight, temperatures begin to moderate again, and we should even head back toward “normal” by Wednesday or so. But first, we’ve got a few more showers and wind chills to deal with.

A powerful, late season Nor’easter centered over New York City is drawing in abundant Atlantic moisture and, on its back side, unseasonably cold air from Canada. The result is historic quantities of late season snow in interior parts of New York state, west central Pennsylvania and due south through the mountains of western Maryland and West Virginia.

The current bout of winter-like weather brings blustery rain showers today with - yes - snow mixing in at times in high elevations to the west. Temperatures moderate some into mid-week, but two more weather systems may bring chilly rains back to region Wednesday into Thursday and over the weekend.

Forecast: Some showers and thundershowers today before heavier rain arrives Sunday

We’ve been wanting some rain lately, so I guess we can’t complain too much that it’s coming on a weekend. Today may end up pretty salvageable as the early day should be largely dry, and we may dry out again during the evening for a bit after any showers or storms. But, tomorrow we’re probably not as lucky as a strong storm wraps up near the coast. Overall, beneficial rains are a good bet, as are some gusty winds and cool temperatures heading into early next week.

Earth’s coolest March since 1999; global warming on the wane?

The heat in the U.S. during March was off the charts. How many times have you heard about the 15,000+ warm weather records that were set, many crushed? But the U.S. makes up just two percent of the planet and the rest of it wasn’t so hot. In fact, by recent standards, the Earth was cool - the coolest March since 1999.

Though it rained off and on much of the day, it has not amounted to much (except in some places to the south and west). Mainly light activity has been at least enough to wet the ground and remind us it can still rain around here! Highs near or above 60 happened after midnight, and we’ve fallen into the cool and clammy low-and-mid 50s this afternoon. The risk for showers continues through the night, but they’ll remain rather light, and we should see breaks in the action here and there.

Americans connect dots between global warming and extreme weather

Most Americans get it: global warming is intensifying heat waves and extreme precipitation to some degree. That’s the take away from a new public opinion survey from the Yale Project on Climate Change Communication and George Mason University Center for Climate Change Communication.

Grading our 2011-2012 winter forecast

As always, we grade our winter and summer seasonal outlooks in spring and fall respectively. In short, we did poorly this winter with not much of a silver lining. The major consolation being that we can commiserate with the authors of the other winter outlooks we encountered.

A bell tower view of Discovery over Washington, D.C.

Forecast: Clouds keep things cool today; warmer finish to week with potential weekend rain

The most frustrating aspect of today’s weather is that mostly cloudy skies keep us rather cool, but likely fail to produce the meaningful rain we need. Still, some light showers are possible and are better than nothing. Warmer times return tomorrow followed by a fantastic Friday. The weekend, especially the latter part, features a chance of more significant rainfall.

We’ve only received 0.16” of rain all April and are nearing a 5” deficit on the year but tomorrow we have the opportunity to maybe double April’s total. That’s not a ton of rain by any stretch, but we’ll take what we can get and it will lower pollen counts. The flip side is that you’ll need your jackets as temperatures struggle to reach 60.

Cool air coming back East late week; overall, quieter weather pattern

Now that one of the most-anticipated and feared tornado outbreaks in recent times is over, the pattern will calm down for a while. But that doesn’t mean it will be sunny and 75°F everywhere. The jet stream will soon change its shape from one that brought severe weather in the Plains and hot weather in the East over the past few days, to one that will dry out the mid-continent and bring chilly and showery conditions back into play east of the Mississippi.

Sun unleashes dramatic flare

At 1:45 p.m. Monday, an outburst from the sun was captured by NASA’s Solar Dynamics Laboratory. This violent burst of solar wind - known as a coronal mass ejection - was not pointed towards Earth. The sunspot area that emitted this flare is rotating and will face the Earth in a few days says Dan Satterfield at Wild Wild Science.

Temperatures in the upper 80s to near 90 this afternoon are a good 15 degrees, or more, above normal for the date, and we’ve come pretty close to record highs. We’ll have to wait on official numbers, particularly at BWI, where a reading of at least 89 has been recorded and the record is 90. We cool back down tomorrow.

We begin the week with our warmest day since last September, with temperatures rising well into the 80s. The balance of the remainder of the week is not as warm, but still mild, with temperatures mainly in the 70s. However, a strong cold front charges through the region Saturday, bringing the week’s best rain chance and then cooler weather for Sunday.

Forecast: And now for the really, really warm stuff!

Just when you think it can’t get any warmer, highs head for near or past 80 today, and at least to the mid-80s tomorrow! Heading into midweek, the storm system that sparked a tornado outbreak across the central Plains yesterday into last night moves through. But by that time, all we probably get out of it is some clouds, maybe a stray shower, and cooler but still fairly mild temps.

Today gets our warm stretch going, with temperatures into the 70s across the area, and by tomorrow that might seem cool. 80s are a good bet both Sunday and Monday as warm air shoots north in the environment out ahead of the major severe weather maker expected to impact the Plains and Midwest this weekend. No real cool air in the near future, either.

And he thinks it’s because the thermometer is in a bad location, prone to winds blowing across the hot runway surface. I’m not convinved.

The weather during the Titanic disaster: looking back 100 years

This week marks the 100 year anniversary of the sinking of the RMS Titanic. Thought to be almost unsinkable, the flagship of the White Star Line struck an iceberg and sank about 375 miles southeast of Halifax, Nova Scotia—about the latitude of Providence, RI. As is well known, the much-storied disaster took the lives of about 1,500 passengers and crewmembers, almost two-thirds of the total complement of 2200. But what were the weather conditions preceding, at the time of, and following, the great disaster and did they contribute in any way to what happened, or how it happened?

The pattern shift that finally balanced things out a bit this month after the prolonged stretch of extreme temperatures in March, is now ready to show a new face. In the East, a few chilly days this week will give way to a short burst of very warm air late in the weekend. And a large spring storm will soon move into the West and notably increase chances for severe weather, including tornadoes, in the middle of the country during the next few days.

Forecast: Chilly, windy, dry today and tomorrow; big warm-up by weekend

Low pressure stalled around New England combines forces with a moderate high pressure area dropping into the Midwest to send in chilly, windy weather today. Highs should range through the mid-to-upper 50s into the low 60s under partly cloudy skies. But winds from 10-20 mph with gusts to 25 mph mean it could really feel like the upper 40s to middle 50s a lot of the time. Look for improving conditions late this week with warmer weather (70s!) this weekend.

Those winds sure have been noticeable today, with at least one gust past 40 mph at National Airport midday. Fortunately, temperatures in the mid-60s to near 70 made it a pretty bearable wind. However, a cold front passing through this evening and overnight will help draw cooler air back into the region for tomorrow. And wind -- as well as fire concerns -- will still be something we have to deal with at least through then.

We’re now about 4” below average on the year. Given the winds expected today, conditions will be ripe for fires across the area, and perhaps we’ll deal with that again tomorrow.

Not too much to say bad about today. Winds were extra gusty through much of it, but with afternoon temperatures near 60, and wall-to-wall sunshine, I think it probably deserved more than a 6! As we head toward nightfall, winds diminish noticeably, but they probably won’t fully disappear. Temperatures are going to drop quickly though, and if you’re north and west of the city, you might want to prepare fragile plants for the possibility of an overnight freeze.

The Tidal Basin has the cherry blossoms but Bull Run has the bluebells. The bluebell, which carpet the forest floor in large areas along Bull Run, is a native perennial plant that can grow up to 2.5 feet tall and prefers moist, wooded areas.

Pollen expert: Tree pollen decline “seems to have already begun”

Those of us with pollen allergies have suffered early and often this spring thanks in large part to abnormally warm conditions. But there is an upside: tree pollen counts - which normally peak in April - may have already started to trend downwards.

Taking advantage of the dry weather for gardening

The warm and dry weather has been great for getting garden chores but this dryness has got to stop. We are so close to drought status it is not funny.

Masters weather: Severe thunderstorms threaten before sunny weekend

The famed Augusta National Golf Club got raked by severe thunderstorms Tuesday night and could have a repeat performance later today into tonight. On Friday, dry air oozes south - setting up a picture perfect finishing weekend for the 2012 Masters. But the change in weather promises a change in course conditions, adding a wrinkle into golf’s “tradition unlike any other.”

Weather forecast accuracy versus skill: skill is what matters

In his post on AccuWeather’s new 25-day forecasts, Jason Samenow says, “Never mind, the skill in forecasts rapidly deteriorates beyond 5-7 days.” Notice he didn’t say accuracy because for meteorologists the score that counts in judging forecasts is “skill,” not “accuracy.”

When is the Washington D.C. area’s last spring freeze?

Less than two weeks ago our overnight lows were in the May-like 50s, but since then we’ve flirted with the freezing mark twice in the past week. 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.

Forecast: Sunshine from here to Easter, overnight frost chance colder suburbs

The Easter bunny is going to have no issues with this forecast. Barely a cloud will interfere with our blue skies through Sunday with highs mainly in the 60s. The only concern is the possibility of scattered frost in outlying areas tonight and especially Friday night. The lack of rain is nice for us but not for gardens and lawns

PM Update: Clearing skies with a slight chill tonight, sunny Thursday

A cold front sinking south through the mid-Atlantic has shoved away the blanket of clouds and clearing is underway. Clear cool nights and sunny seasonably mild afternoons have arrived for an extended stay. We could really use some rain, but we may as well enjoy the incoming stretch of splendid spring weather.

The three tornadoes that touched down in the immediate Dallas-Ft. Worth metro region Tuesday were large and violent, at least EF-2 intensity, according to preliminary reports from the National Weather Service. Yet amazingly, no one died.

AccuWeather debuts 25 day weather forecasts

No it’s not an April Fools’ joke: Accuweather is pushing the limits of weather forecasting and issuing detailed predictions extending 25 days into the future effective today. Consider me highly skeptical about their value.

Forecast: Another run at 70 today, then a couple of average April days

After highs today shoot for a second straight day near or past 70, temperatures step back toward normal Thursday and Friday. We could use some rain but there’s not much to be had over the next several days. We’ll trend a bit warmer again this weekend, so start making your outdoor plans now!

PM Update: Mild through Wednesday with increasing clouds, slight shower chance

What a spectacular day it was. High temperatures reached into the low 70s after scattered morning frost in our colder suburbs. No frost tonight with warm southerly flow and an incoming blanket of clouds. Very mild Wednesday, but look for lots of clouds and the slim chance of a shower.

Republican meteorologist Paul Douglas: conservatives should embrace climate science

Meteorologist Paul Douglas, CEO of broadcast weather and founder of several companies, in his essay “A Message from a Republican Meteorologist on Climate Change” pleas with members of his party to trust climate scientists when they say human-caused climate change is happening and having profound effects on our weather and the environment. Here are some key excerpts, followed by my reaction...

Forecast: A spectacular spring day; slight shower chance Wednesday

As we bounce our way toward the Easter holiday weekend, we continue to at least keep a mostly seasonal to warm pattern in place. Gardeners are looking for more rain than I can find currently with only a few shower chances tomorrow and again on late Sunday. Otherwise, highs mostly in the 60s and lows mostly in the 40s and 50s is nothing to complain about here in the heart of meteorogical spring.

PM Update: A frosty chill tonight, but turning spectacular on Tuesday

After our dry March, I guess we should all be rooting for a bit of rain, but the forecast is so pleasant it’s hard to do so. Today’s blustery highs near 60 will see a good boost tomorrow along with plenty of sunshine. But first, we’ve got a cold night ahead, with some frost and freeze concerns to the northwest of the city.

Warm weather records smashed, more than 90 cities with warmest March on record

During the course of March, large chunks of the U.S. experienced spells of warm weather unmatched in recorded history. 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.

March 2012: Warmest on record in Washington, D.C.; 6th driest (tie)

Our very warm March has come to a close and not only was it the warmest on record (since 1871), but it also extends our streak of above normal monthly temperature averages to 5 months in Washington, D.C.

Forecast: Lots of sun, little meaningful rain in week ahead; frost advisory N and W of D.C. tonight

While not as warm relative to average as much of March, the first week of April promises to be delightful. Most days feature abundant sunshine with temperatures in the 60s and crisp, cool nights. The best chance for showers is sometime Wednesday; otherwise, dry weather dominates. It’s premature to worry about drought, but area rainfall deficits are mounting.

Spring snow in the forecast late in the week (April Fool’s!)

Just when you thought the “winter-that-wasn’t” was long behind us, one weather model is forecasting a major snowstorm later this week. With unseasonably cold high pressure forecast to move into eastern Canada, the stage may be set for a rare spring blizzard. An April Fool’s post.
