PM Update: Severe storm threat late Friday

Today was just about perfect headlined by a light-to-moderate breeze, low humidity, a few clouds and highs in the low-to-mid 80s. How quickly things will change. A strong, dynamic frontal system charges into the region Friday, triggering thunderstorms - which may be severe - especially into the evening hours.

Refreshingly cool start to June forecast in eastern U.S., Washington, D.C.

After the sweltering 90+ days on Monday and Tuesday, many feared it was a harbinger of a brutal summer. Not so fast. The latest data and projections signal cooler than average weather for the first 10 days or so of June across the eastern U.S.

Severe thunderstorm and tornado potential Friday in Washington, D.C. area, a closer look

An ominous set of ingredients are coming together to produce the potential for a severe thunderstorm outbreak in much of the mid-Atlantic Friday, including the Washington and Baltimore metro areas. These storms may affect the region during the afternoon and evening rush hour.

What a great end to the month! But tomorrow looks like a more trying day with the potential for late day storms that could be severe. Keep close track of the forecasts and be safe. Saturday is promising to make up for it with its finest - 70s for highs. So plan on getting out there to enjoy...

PM Update: An unthinkably nice Thursday

Clouds hung around today near and east of I-95 as a cold front only slowly pressed eastward. The front was held up by post tropical storm Beryl which poured rain in southeast Va and the southern Delmarva. Everyone clears out tonight as the front and Beryl race off to the northeast. Dry air and beautiful sunshine settle in for Thursday.

Manhattanhenge: Sunset and streets aligned in unique spectacle; a D.C. equivalent?

The summer solstice is still three weeks away, but this evening might offer New York City residents an enchanting sunset experience on the streets of Manhattan. Sun-observing enthusiasts call it “Manhattanhenge” – one of only two days of the year when the setting sun aligns perfectly with the city’s east-west street grid.

Oklahoma City pounded by severe weather Tuesday, and more on the way today

Severe weather erupted across Oklahoma yesterday, with considerable damage done to a number of places including Oklahoma City. While the primary issue was hail and high winds, at least one tornado and potentially a few more touched down as well. More severe weather is scheduled to impact the southern and central Plains today.

Forecast: Heat and humidity go on hiatus

We’ve weathered the season’s first heat wave and now it’s back to more typical temperatures for the next several days, though we’re still on the warm side today. Exiting with the heat is that sweaty humidity, which goes super low for a spectacular day tomorrow. Despite drier air moving in, we still face the potential for a lingering shower today and more showers and thunderstorms late Friday.

A Marine Corps sunrise on Memorial Day weekend

In the spirit of Memorial Day, I filmed a sunrise at the Marine Corps Memorial this past weekend. It was one of the more interesting sunrises I’ve seen from a weather perspective. Ground fog and low-level clouds moved rapidly to the north while mid-to-high-level clouds moved to the southeast.

Hot weather continues today. Fortunately, relief is quickly on the way with a cold front tonight bringing more thunderstorm chances (as early as this afternoon), lower dew points (tomorrow), and cooler temperatures (by tomorrow night). Another weather system approaches our area by Friday with an effort to disrupt the first part of our first June weekend with showers and storms.

Forecast: Muggy Memorial Day, drier air moves in mid-week

It’s the unofficial start of summer today and while it’s customarily hot and humid, there are several things to be thankful for: 1) Lower storm chances today compared to Sunday. 2) No air quality alerts. 3) We made it this far without hitting 90. But...90 or so is a good possibility today and Tuesday before cooler, drier air arrives Thursday.

Beaches & pools still look like a great bet through Monday even though we can’t rule out a late-day thunderstorm (20% chance today, 30% chance tomorrow). While outside, please take care to drink water & lather on the sunscreen. Note that air quality may not be great – today it’s Code Orange - until we hopefully get a cold front to clear the air a bit by Wednesday.

Hope you’re ready for some summer, as it’s here the next few days. Though, it seems like the first real heat often coincides with Memorial Day weekend, so perhaps it’s as fun for some as the BBQs and other outings? Feel free to let us know. If you don’t like the heat, well, you might be out of luck as it appears there is no major break anytime soon.

Mother Nature gets the summer season started in style, that is if you like classic hot and humid DC area weather. Slap on the sunscreen, beware of rip currents, and otherwise prepare to enjoy a perfect weekend for the pool. Whatever you do, stay hydrated. Afternoon heat indices into the mid-90s will take their toll if you’re out in it too long.

The unofficial start to summer is here, and Mother Nature will oblige with typical summer conditions — starting fully by Saturday — into next week. Muggy 90s are possible, but with some potential mitigation by periodic breezes, and isolated thundershowers. Are you ready to flee toward the cooler water and/or beaches this weekend?

The warming trend continues into tomorrow with the potential for a few scattered storms ahead of a hot holiday weekend that should feature fewer storms, but even more humidity.

We’re likely to get there this weekend with heat indices even higher. The good news is lower thundershower chances (but still a chance) starting tomorrow. For you beach bums, we’ve got the holiday weekend beach forecast, too , so check it out dude!

Scattered thundershowers have many of us dashing through a downpour or two into this evening. Because the storms are slow moving, localized flash flooding is possible so drive with caution. We continue with a chance of showers and storms tomorrow, before we transition into a hot holiday weekend with temperatures making a run to near 90 or higher.

We have two days (today and Thursday) before low pressure gives way to high pressure at the upper levels of the atmosphere. That change doesn’t necessarily mean an end to shower and thunderstorm chances Friday through Memorial Day. But it should mean more sun and building heat with highs likely near or past 90 degrees.

Given the intensity of the tornado, at the very top of the scale (EF-5), little could’ve been done to avoid the catastrophic economic losses from the Joplin tornado one year ago. But Mike Smith, in his new book, “When the sirens were silent,” makes a compelling argument that the people of Joplin were let down.

One year ago tomorrow, Joplin, Missouri was impacted by a most-feared EF-5 tornado with winds over 200 mph. When the early-evening storm was through, and skies began to clear, the devastation left behind by was brutally apparent. Joplin has recovered significantly, if irregularly, in the year that’s passed since the tornado.

Forecast: An unsettled week ahead

A weakened Alberto continues to churn off the Southeast coast but will have little impact for us except for sending a little extra moisture our way. Most of our weather this week is due to an upper-level area of low pressure and associated cold front approaching from the west, which together bring us an extended dose of warmth, noticeable humidity, and a daily chance of showers and storms.

Ladies and Gentlemen, welcome the first named storm of the 2012 hurricane season, Tropical Storm Alberto. The east-to-west (onshore) circulation around the north side of Alberto means increasing clouds and humidity levels here in the D.C. area over the next couple days. By this evening, the threat for showers arrives, too. Warm, unsettled weather with the potential for some thunderstorms stays through midweek

That said, Sunday should still be a pretty decent day.

Fire up your flux capacitors! It’s time for an annular solar eclipse that’s going back to the future. The moon crosses in front of the sun, handing sky gazers an annular eclipse that starts Monday and ends on the previous Sunday, according to NASA and noted eclipse expert Fred Espenak. This will be the first solar eclipse visible in 18 years in the contiguous 48 states.

Viewpoint: pitting climate change research against weather research is unproductive

Some feel the argument that resources for weather forecasting are more important than for climate change prediction is an affront on the importance of climate change modeling and not helpful in advancing broader goals in advancing atmospheric science

Forecast: Wonderful weather through at least Saturday; uncertain Sunday yet

We have a winning weather pattern for at least next 72 hours with solid sunshine, comfortable daytime temperatures in the 70s, and cool overnight lows. Sunday is still tricky as a low pressure area near the coast could bring in some clouds and maybe even some shower chances late Sunday into Monday. If the low fails to visit, temperatures should go warmer (80s).

PM Update: Here comes some fantastic weather

It’s been a pretty decent day out there, with temperatures reaching highs in the 80s most spots. Perhaps a bit cooler than I expected in the morning forecast, thanks in part to a bit extra cloudiness and a slower shift in winds to the west. But, that wind shift is here, and humidity levels are already dropping. By tomorrow, that taste of summer will be a memory for a while.

Even though we could still use more rain, after a few days of murky conditions, it’s nice to see the sun make a return. We start that process today, and head full steam into it for the next several. Outside a slight shower or thunderstorm risk this afternoon into early evening, the rest of the week features several days in which it might be hard to find much in the way of cloudiness, let alone any more precipitation.

PM Update: Scattered storms this evening; drier air trickles in on a warm Wednesday

After a round of morning downpours, we’ve had a warm, humid day. Enough sun has snuck through the expansive cloud cover to elevate temperatures into the upper 70s. A slow moving cold front brings the potential for showers and storms this evening, then drier air creeps into the region into Wednesday. However, another cold front could set off a stray shower/storm late in the day.

Depending on your location, you’ve seen either periods of showers or a fairly consistently showery day. Some of the most widespread activity so far, including embedded heavier downpours, is now passing through the region. Despite the clouds and rain, high temperatures are ranging from the mid-60s to the west to around or above 70 in the I-95 corridor and east. Additional showers, some potentially intense, continue to move through the area into the night.

Between today and Tuesday night, around 1-4 inches of rain is possible. The clouds and rain hold temperatures down in the 70s but it’s plenty humid. The drying trend starts Wednesday, with highs then close to 80 through the weekend.

Forecast: Some showers possible today, then decreasing rain chances to start new week

Overall, there’s not too much to worry about this weekend weatherwise, but we may run into a few showers and maybe a rumble today. By tomorrow, that threat should wane to a very slight risk, yet we’re still going to have a frontal boundary around, so “totally dry” is not a sure bet. If you weren’t a fan of the 80s we’ve recently seen, at least a return to near normal highs is around the corner.

NatCast: Showers may drop by for a visit

It doesn't look like a washout by any means, but there could be noticeable rain drops at times. Temperatures are quite comfortable though.

PM Update: Scattered showers and storms this evening; gradual weekend drying

The work week has closed on a warm, sticky note. It sure felt like a summer preview with temperatures in the 80s, high humidity, and a few thunderstorms. Some additional scattered showers and storms are likely this evening before a drying trend begins. We can’t totally shake shower chances on Saturday, but Sunday promises to be rain-free.

Some “marginal” severe storms possible this afternoon and evening

NOAA’s Storm Prediction Center sees the potential for some severe thunderstorms this afternoon and evening in the D.C. metro region, but it’s qualified potential. In their latest update, they say there’s a 40 percent chance of a Severe Thunderstorm Watch being issued. In the graphic above, the threat of damaging winds and large hail is “marginal”.

Forecast: Storms possible today, and a pleasant weekend ahead

After we struggle with today’s clouds, mugginess, and increased storm chances, we actually may have a more pleasant weekend ahead. Don’t get me wrong, a few clouds and some showers could pop-up here and there, yet warm temperatures remain — along with less muggy-feeling conditions. That’s when we may be fairly cloudy with increased shower chances again. Enjoy prime days Saturday through Monday, outdoors (with sunscreen), such as the Montpelier Wine Festival!

PM Update: Summer warmth arrives, isolated showers and storms into Friday

The surprising cool, marine layer capped temperatures this morning, but a surging warm front coupled with May sunshine pushed afternoon temperatures to 80 and higher. A couple isolated storms could drift into western parts of the region this evening. Otherwise, it’s mild overnight and summery on Friday, with somewhat better late day storm chances.

Beat the drought with this arsenal of tough garden perennials

We’re back in the fast lane to drought. Since March 1, we’ve received less than half our normal rain. Fear not, for there are plenty of plants that will stand up to just about the worst dryness that the season can offer up. But please Mother Nature, that is not a challenge!

Forecast: Warmer days ahead, some limited thundershower chances

Yesterday’s chilly maritime airmass should have retreated, so let summer roll on in. I’m taking my chances forecasting a warm-up back into the 80s. A smattering of thundershowers is possible today and tomorrow but general rains are a no-go. With a little luck we push the showers south of the area for the weekend, but in return get liberally pollenated.

PM Update: A tale of two air masses today, but summerlike tomorrow

One of the main things I noticed about today was humidity—guess it’s that time of year. Variably cloudy skies, and a front draped across the area, led to a wide range of temperatures. Highs have only hit the 60s to the north and east, while they’re past 80 to the south and west. In the middle, D.C. has reached the 70s. So far, the risk of storms seems subdued compared to potential, and it’s possible we’ll make it through the daylight hours without much of note.

Washington, D.C. summer 2012 weather forecast: Brutally hot again, and dry

Forecast: Summery days with some showers and storms

We had plenty of spring-like weather during the winter, so I guess it’s only appropriate we now see summer weather during spring. The next few days are about as summery as you can get in early May, with highs mainly in the 80s and the chance of an occasional shower or thunderstorm. We’ll even notice a bit of humidity.

How did you like our warmest day since April 16? Today’s high climbed to 84 - the average high on June 15. After a muggy overnight, we’re right back in the same temperature territory Wednesday. Showers and thunderstorms enter the picture late tonight into Wednesday, a couple of which may be strong.

Summer-like warmth and humidity return East, but probably not for too long

Round and around we go; cooler, then warmer, then cooler, and so on. Unlike March, when the global circulation almost uninterruptedly delivered warm conditions nearly everywhere in the country for weeks on end, the weather pattern in April gave us a few different looks. Anticipate lots of weather transitions to continue into the first part of May.

April 2012: 21st warmest on record (tied) - barely warmer than March; 30th driest

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.

Forecast: Morning showers/storms but warm today into the weekend

After our unusual (for this year!) cool spell, a warmer weather pattern is arriving in the area for a visit. Unfortunately, forecast details over the next several days are a bit complicated, but the general view is that we’ll see temperatures into the 70s and 80s with occasional shower and thunderstorm chances. Cooling trends return later this weekend with a cooler pattern favored by next week again.
