FORECAST IN DETAIL

The unofficial start of summer is here and the heat and humidity have arrived right on schedule. Most spots soar above 90 today and it remains warm to hot for the duration of the work week. The best chance of showers and storms in the next five days comes tomorrow and Friday, with isolated opportunities today and Thursday.


Radar: Latest regional radar shows movement of precipitation over past three hours. Powered by HAMweather. Refresh page to update. Click here or on image to enlarge. Or see radar bigger on our Weather Wall.

Today (Monday): This may be the hottest day of 2010 so far as the mercury sets it sights on the low 90s (we hit 93 last Thursday). Noticeable, but not oppressive humidity will make it feel like the mid-90s at times. A few isolated thunderstorms may (20%) fire up late this afternoon and this evening, but mostly around the mountains. Still keep an eye to the sky and weather radar. Confidence: Medium-High

Tonight: The flow coming in from the south means a muggy overnight period. Lows only fall to the upper 60s in the cooler suburbs with mid-70s downtown. Confidence: Medium-High

Keep reading for the forecast through the work week...

Tomorrow (Tuesday): A weak cold front bumps into this sticky air, so showers and thunderstorms -- some with heavy rain -- are likely (60% chance) in the afternoon and evening. Before the showers and storms start to pop, we'll have some sunshine -- elevating temps well into 80s. Confidence: Medium-High

Tomorrow Night: The passage of the storms and the cool front provides some relief from the muggy air. Lows finally drop back below 70 in town and close to 60 in the cooler suburbs. Confidence: Medium-High

A LOOK AHEAD

Wednesday is not as humid but still on the warm side. Under mostly sunny skies, we warm into the mid-80s. Mostly clear and mild Wednesday night, with lows 60-68 (suburbs-city). Confidence: Medium-High

Thursday's potentially hot as winds from the southwest bring back warmer than average air. Highs probably reach the low 90s. By late afternoon and overnight, we may see a few storms (30%). Confidence: Medium

We'll have a better chance of showers and storms Friday as another cold front sweeps through the region. More clouds means it probably not as hot, with highs in the upper 80s. Confidence: Medium

We have mostly sunny thunder here SW of Front Royal. There's a storm to the SE with thunder every 10 seconds or so, but clear skies everywhere else.

No posts yet??? Interesting...

Basically, May has earned a B-minus [bit on the cool side & dry; too much long-sleeve weather], while meteorological spring 2010 gets a B. There's been a bit too much whining by the "much-needed-rain" crowd, who have also been trying to mess up my dance evenings with rainy spells [though about half of those have failed to materialize as predicted! When in drought, leave it out.]

Wondering whether Tom Skilling will do a weather segment today or whether WGN's general proclivity towards Memorial Day baseball will bump the "news at noon" today...or worse yet, some rerun of "Scrubs", etc. There has been a bit too much pre-emption of the WGN newscasts lately. And they never give us their "5;30 pm news" on the "national" channel.

Speaking of TV meteorology, Kim Martucci has been her usual active self on the News 4 weekend beat. Haven't seen too much of Bob ryan yet, as I've been tending to stick with Fox5 and Sue Palka in the 11 pm slot...may switch to News 7 more often. And I hope News 7 doesn't do too much with News Channel 8...DCRTV keeps saying they plan to scrap the present format for mostly or all Politico at some point. I think some Politico programming would be welcome, but not a full replacement of local news. My take on NC8 is that they tend to keep re-running the same taped half-hour newscast with few or no live updates.

Hearing the same thunder Eric reported and it's raining on the Blue Ridge in Warren Co... I'm going to go take down the flag...

BTW, the National Memorial Day Parade is on the Military Channel [Comcast 112 for those of us with digital in Arlington], 2-4 pm. Gottaswing has their swing dance team in the parade, and also a dance tonight at Chevy chase Ballroom, 8:30--my attendance depends on Metro and weather conditions--MNR crowd should refrain from evening thunderstorms.

BUMMER!!!... WGN is bumping news & Tom Skilling for Cubs @ Pittsburgh--but might be better than bumping it for some stale movie or "Bewitched" reruns...they are supposed to have news at 10 PM tonight. I'm not sure if they ever do noon news on weekday holidays, anyway.

Just enough of a breeze out there that it's not too uncomfortable out walking around.

Bombo: I think everybody was waiting for something to happen. Now the storm clouds are smeared to the east, very little thunder, and still mostly sunny elsewhere. But the storm seems to have kicked up some 15 mph wind gusts here.

Radar is beginning to look pretty impressive, chiefly in the West Virginia eastern panhandle. But it's mainly warm-sector airmass activity...closest outflow boundary to us is way out in Arkansas. The frontal boundary is even farther west, and seems to be stationary over much of its extent. [The storms in West Virginia and Western Va. could set up new outflow boundaries later in the afternoon.]

Temp has dropped to 76.1 after an earlier high of 84... sun now making a comeback though...

Dew point hovering near 70 = ugh.

Lots of action to the southwest but I see a gap developing.

I hope Think Spring is happy with today's weather. As for me, I'm ready for snow and cold again. One day like this is too many!

Just ran from a gorgeous storm up in Loudoun County. A large, well-shaped anvil was clearly visible in Leesburg at 5:00pm. The storm remained visible as I drove down toward Fairfax City, but was still largely north of me when I got home to Merrifield. Not sure from looking at the radar if that one will make it far enough south and east to catch me.

Yes, ThinkSpring did like this day (and this weekend) very much. Thanks for asking. :)

And sorry, maymay1, but we have to go thru many more of these kind of days to make up for the winter we had.

A major texas heat wave is building. And it will overspread the dc area at some point! Happy Meterological summer!
