PM Update: It’s about to turn hot

Today has been simply magnificent with a mix of sunshine and fair weather clouds, comfortably warm temperatures and low humidity. A very nice evening and overnight lies ahead before it starts to heat up tomorrow.

A Memorial Day sunrise

Very early on Memorial Day, May 30, I was back out with my camera and this time the sky was clear but I found Washington’s sky glow (light pollution) made viewing the planets difficult. Only two of the four planets were visible with the crescent moon. Once again the sunrise salvaged the photo trip.

Arctic Update: Petermann’s travels

Back in August 2010, CWG helped break the story that a 97-square mile ice island had broken off from the Petermann Glacier in northwest Greenland. Since then, the massive chunk of ice has been on quite a journey: It hit the beach on a small island, broke up into many smaller pieces, and picked up some hitchhikers in the form of iridium beacons used to track the pieces.

Shelf cloud over Fairfax

Late in the afternoon last Friday (one week ago), scattered thunderstorms developed west and north of Washington and moved north-northeast. The arrival of the thunderstorm was proceeded by an ominous-looking shelf cloud that heralded the arrival of gusty winds which was followed several minutes later by heavy rain. I observed about a dozen lightning strikes from my location at Fairfax Town Center, but nothing that I would classify as severe weather. The shelf cloud did look cool as it pushed through the area.

PM Update: Delightful dry air to close out work week

Following three straight days of hot and humid 95+ degree weather, today’s (by comparison) arid 80s have been heavenly. And it gets better tomorrow. We enjoy a crisp fall-like evening tonight before a day replete with sunshine Friday and pleasantly warm temperatures.

For the second straight day, the mercury has reached at least 95 degrees at Reagan National. Even during the record hot summer in 2010, that didn’t happen until late June! At Dulles, the temperature has reached at least 94, tying the record from 1991. After a muggy overnight, we have another day of heat tomorrow which may be capped off with a thunderstorm

Our Tornado Voyeurism Problem

During this tragic tornado season, we have been inundated with awe-inspiring videos of tornadoes ripping apart communities, from Joplin, Mo., to Tuscaloosa, Ala., and Raleigh, N.C. – and places in between. While lives are being lost, many of the videos show amateur chasers cheering the unprecedented weather, too caught up in the thrill of witnessing Mother Nature at her rarest (and deadliest) to comprehend the decidedly grim reality of what is taking place.

Forecast: Two more hot and humid days

A monstrous dome of high pressure has enveloped the eastern 2/3 of the nation in a hot and humid air mass. However, fortunately, this first-of-season heat wave is short-lived as a cold front rescues us tomorrow evening. Some heat and humidity could sneak back into the area this weekend, but it doesn’t look to rival our current super-steamy levels.

We start the Memorial Day weekend with low-to-mid 80s and another risk of daytime showers and storms, then it gets hot. And, I mean really hot... especially by Monday, when we could see readings into and past the mid-90s.

What a great summer holiday weekend coming up. Maybe not ideal for you “humidiphobes,” but by D.C. standards it won’t be oppressive. In the meantime, the storm that’s been ripping the Plains and Midwest disintegrates as it approaches our area, but a few thundershowers are still possible at times into the weekend.

Forecast: Warm and getting hotter

We’ve settled into an early-arriving summer pattern, and so far our somewhat humid 80s have been tolerable. But we may not feel the same about 90, which we could near or eclipse a few times over the next several days as typical summertime storm chances persist.

Severe Thunderstorm Watch until 6 p.m. The upcoming Memorial Day weekend is typically the unofficial “mile marker” for the start of the summer season. However, our atmosphere has decided to accelerate things just a bit by delivering a classic summer pattern this week - highs in the 80s to near 90, moderate-to-high humidity, and daily storm chances.

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.

What happens when you mix together cold air high in the atmosphere, moist flow off the ocean and a hot May sun? You get thunderstorms capable of producing hail.

Tornado sighted near Hagerstown, Md. Tuesday: video

With winds aloft from the south and from the east at ground level, the atmosphere was spinning last night.

Some scattered showers and storms are possible through this evening, and a few of them could be severe.

Airline safety: Is the fear of a lightning strike warranted? JetBlue plane struck

On December 8, 1963, a 5-year old Boeing 707 Pan American World Airways jetliner crashed near Elkton, MD, killing a total of 73 passengers and 8 crew members. The plane, en route from Puerto Rico, had stopped at Baltimore and was on its initial approach to Philadelphia, the final destination. Since thunderstorms were in the vicinity, it was thought that lightning had caused the vapors in a reserve fuel tank to explode. Before you come to the conclusion that lightning represents an extreme hazard for commercial aviation, you should know that that accident—almost 50 years ago--represents the last time that lightning was responsible for commercial U.S. airline casualties. A very good record indeed! Nevertheless, lightning does strike airliners all the time.

Rare, complex flow pattern behind weird weather

Unless you’ve been trapped in the depths of a DC Metro underground station by inoperative escalators and elevators, you know the several contiguous days last week of positively delightful spring weather has been replaced over the weekend by less than totally pleasant conditions expected most of this week. In his post last week Jason asked “what’s the cause of this lovely stretch of San Diego-like weather in Washington, D.C.?” He answered “we can thank an atmospheric pattern known as an omega block”. The question now is what’s the cause of the prolonged stretch of less than perfect (icky, lousy, unsettled, crappy, etc.) conditions this week? Perhaps surprisingly, the answer is the same: an omega block. How can that be?

Forecast: Periodic downpours today

A swirling low pressure gyre is at its most powerful today, generating heavy showers and thunderstorms at times, keeping plenty of clouds in the sky, and holding our temperatures down in the low to maybe mid-70s. This pattern persists through the week, although the odds of showers each day gradually diminish as it loses some steam.

Morganza spillway from space: image of day

Earlier today, we reported on the opening of the Morganza spillway in Louisiana to divert flood water from the Mississippi River into the Atchafalaya River to protect Baton Rouge and New Orleans from an aquatic assault. NASA Earth Observing (EO-1) satellite presents a remarkable view of the spillway from space.

In St. Louis, pilot was unaware of approaching tornado

This story is the second in a two-part series on the strong tornado that struck Lambert-St. Louis International Airport on April 22, 2011, causing extensive damage to airport facilities and numerous injuries. Part I detailed how people inside the airport terminal buildings never received the warning. This post details how at least one airline pilot, and passengers, were also unaware of the danger until it was swirling around them. It illustrates what some say is a fundamental problem with the way weather information is shared among the Weather Service, the Federal Aviation Administration and airline personnel, and then disseminated

On the night of April 22nd, over at Concourse A at Lambert-St. Louis International Airport, Carla Hall, a former contestant on Bravo’s “Top Chef”, was waiting for her return flight to DC after a week of shooting webisodes for Fancy Feast and Purina. Unbeknownst to Hall, most others in the airport, and even airline pilots, a violent tornado was heading straight for the airport.The St. Louis tornado revealed important gaps about aviation safety, including how airport authorities, airline pilots, and passengers receive severe weather information.

As beautiful as the last work week was, this week is ugly. Sunshine is difficult to come by and rain is in the forecast almost every day. Tuesday holds the potential to be the wettest day of the bunch, but Wednesday through Friday are no picnic with afternoon/evening showers in the picture. Even Saturday holds onto shower chances, with Sunday showing the best potential for some drying.

It’s not just tornado numbers mounting at a feverish pace in 2011. Through Thursday, 22 major league baseball games have been rained out so far in 2011 (or in Denver’s case Wednesday, snowed out). That number already exceeds 2010’s season total of 21 rainouts less than one quarter of the way into this season.

On Saturn’s moon Titan, spring rains but no spring flowers

At last, spring has sprung. Heavy, persistent rains have arrived sometimes overflowing riverbeds and gullies. River and lake ice have thawed. Tropical weather systems are migrating north. And at northern latitudes, average temperatures have finally risen above the freezing point of -297 degrees F. 297 degres F below zero? Did you catch that? There is no error. I’m not talking about freezing/melting point of water, but rather methane. And the coming of spring is occurring not on Earth but on Titan, the largest moon of the planet Saturn.

Our big beautiful block

What’s the cause of this lovely stretch of San Diego-like weather in Washington, D.C.? We can thank a atmospheric pattern known as an omega block. In this regime, a big fat area of tranquil high pressure - currently influencing much of the East - sits between two areas of stormy low pressure. The resulting signature of such a feature on the weather map resembles the Greek letter omega, hence the name.

Mississippi River: Record rains drive record flooding

Early this morning, the Mississippi River crested at 47.79 feet in Memphis, Tennessee, 13.79 feet above flood stage and the second highest level on record. Last week, record high crest levels were reached in Caruthersivlle, Mo. and Pocahontas, Ar. Over the next several days, high waters head for the lower Mississippi river through Louisiana. So what’s behind these historic river levels? It is the extreme rainfall that inundated the central U.S. and Ohio Valley during the month of April

Memphis flood: Mississippi river about to crest

In Memphis, Tennessee, the Mississippi River continues to rise. At 10 a.m. central time, the river stood at 47.7 feet or 13.7 feet above flood stage. According the U.S. Army Corps of Engineers (USACE), the amount of water passing through Memphis right now would fill up a football field 44 feet deep in one second. As soon as this evening, the river is forecast to crest at 48 feet (14 feet above flood stage), the second highest level on record. The record level of 48.7 feet occurred in 1937. Downstream in Louisiana, preparations are underway for the incoming flood waters.

Killing killer tornadoes before they strike: Is it possible?

With the number of destructive and killer tornadoes this year already reaching historic levels thoughts often dwell to the question whether we can subdue the beast through varying approaches for weather control. The same occurred the same occurred following the exceptional onslaught of disastrous hurricanes, including Katrina that struck the U.S. in 2005. In following years a number of proposals emerged (or reemerged) for subduing the threat of hurricanes by reducing their strength and/or steering them away from where they would do the most harm. Aside from extreme events, weather modification has been a subject of considerable interest, for example in regard to rain making to alleviate droughts, keeping rain off the Beijing Olympics and snow outside the Moscow city limits. None of these efforts have been convincingly demonstrated to be effective and probably never will (personal opinion). So what do we know about the much more difficult problem of the subduing tornadoes?

Storm warning expert: Power outages a principal cause of high Alabama tornado death toll

On Wednesday, we explored some possible reasons for the high number of fatalities from last week’s horrible tornado outbreak in Alabama and other parts of the South. These included the intensity of the tornadoes and their fast forward motion, the high mobile home density, the abundance of trees (which made the storms hard to see), complacency (i.e. “this won’t happen here” mentality) and power failures from storms earlier in the day which knocked out essential communications. Meteorologist Mike Smith, CEO of WeatherData and author of “Warnings: The True Story of How Science Tamed the Weather” believes the power outages were indeed the primary cause of the high death toll.

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.

So how did you like April 2011? I personally couldn’t complain. It wasn’t that hot and only occasionally chilly. In fact, the quick summary is slightly warm and slightly wet.

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.

Forecast: Cool showers today, sunny tomorrow

We come to expect better and better weather as we get into May. But today’s cool showers remind us that Mother Nature doesn’t always meet our expectations. Payback is a beauty of an afternoon tomorrow, but then the trend of alternating nice and unsettled days continues. What does that mean for Mother’s Day?..

PM Update: Strong storms possible this evening

Tuesday delivered for warm weather fans, with partly sunny skies, a little mugginess, and high temps in the low 80s. The heat and humidity will fuel a line of storms developing along a cold front in West Virginia headed toward the metro region. On the plus side, the rain should hold off until after the evening commute.

Alabama tornado outbreak: why did so many people die?

Almost a week has passed since last Wednesday’s historic tornado outbreak in the South. Tragically, the death toll has reached around 350. In Tuscaloosa, Al, more than 200 people remain missing. It is still difficult to fathom how this catastrophic weather event could have happened, but several excellent blog posts have provided insight into the extreme environmental conditions that gave rise to such a violent outbreak and the societal factors that led to the large loss of life.

Forecast: Warm today with thunderstorms tonight

Our spring weather continues to bounce around and it is difficult to get two days in a row of the same weather. Today we hit the 80s, tomorrow cool 60s, and we could even repeat the 60s on Thursday before 70s Friday and maybe consistent 70s for the weekend too. Temperatures aside, the main weather concern we are monitoring is a slight risk for severe storms tonight as a cold front swings through the area.

PM Update: A Tuesday taste of warmth

It’s been hard to shed the clouds today, but the warm air flow from the south has restored a summery airmass. With only partial sunshine, much of the region has climbed into the mid-to-upper 70s. We do about five degrees higher tomorrow, before Tuesday night’s rain and storms.

The problematic confusion about difference between tornado watches and warnings

During the tornado outbreak last Wednesday and Thursday that spun up 19 twisters in the region, my colleague and Metro section columnist John Kelly tweeted out: “Am I the only person who can’t tell a tornado WATCH from a tornado WARNING? Hard to remember the difference. They need better names.”

Forecast: Turning warmer to start week

The upcoming week presents a wide range of spring weather. Today transitions from cloudy and cool to cloudy and mild. Tomorrow’s very warm before turning very wet late. Then Wednesday we transition to a cool and dry pattern - at least for a couple days - before gradually warming back up. In other words, this week gives everyone something to like and complain about

Forecast: Sun subsides, chance of showers

Yesterday’s perfect spring weather may well put today to shame, but our weather today shouldn’t be taken for granted. Sure, we’ll see a lot more clouds move in along with a shower or two but just appreciate how green your lawn is this time of year and all will be forgiven. Besides, as a cold front and area of low pressure approach as we head into the work week, our rain chances increase and we’ll look longingly back at this weekend and hope for its return.

NatCast: Any showers should wait until late

Intermittent light rain showers are possible...not enough to for a rain out, but dress for rainy conditions. Temperatures are comfortable - in the mid-to-uper 60s.
