Clouds and some light rain through mid-afternoon have limited the severe threat across much of the immediate area, though scattered showers and storms are likely through evening. An isolated severe storm is also possible along with a slight tornado chance, with the greatest odds over east and south portions of the area. One batch of heavier showers approaching from the southwest should arrive during the evening commute. Temperatures that made the low-and-mid 80s won't drop too far overnight thanks to muggy conditions.

Through Tonight: Occasional showers and thunderstorms, some with heavy rain and isolated severe weather, including wind and/or hail and a slight tornado chance, should mostly depart by midnight. An isolated shower is possible after midnight as skies stay cloudy. Temperatures should fall to the upper 60s and low 70s. Watch for some areas of fog by morning.

Tomorrow (Thursday): Heat returns Thursday and it could be quite hot depending on how quickly remaining morning clouds get out of here. We look to run 90 and above everywhere, perhaps low-to-mid 90s with a wind from the west and afternoon sunshine helping out the cause. Can't rule out an isolated late-day shower or storm.

Tornado Alley Germ Center: The Department of Homeland Security has come under fire for quickly choosing a Kansas location to house highly infections pathogens. As (or more) concerning than the tornado risk is the fact that it's close to farmland and animals, both of which could be contaminated should a major problem occur. The new lab is meant to replace an isolated one on a remote island near the eastern tip of Long Island.

Tornado warning in Spotsylvania County with that stronger cell to the southwest. Worst stuff is isolated but lots of it showing some rotatoin here and there.

If you're talking about the batch coming from the southwest, looks more like the 5:45 p.m. to 7 p.m. range that it'll pass through the immediate metro area from southwest to northeast

Are we expecting severe weather to be hitting DC itself? I don't see a watch for the area...

Looks like this severe, with suspected tornado, should be southeast of DC itself -- then more general off to the east. There is a smaller little storm heading toward DC though that bears some watching. about 45 minutes to an hour out.

Compared to the original billing, today's rain has been less than anticipated. Here in the Bailey's Crossroads area we had two showers around 2:15 PM and after 7 PM; none of the heavy rain forecast by TV mets across the board.

If you are wondering what's going on @ WUSA9, DCRTV says that Tony Pann will be leaving when his contract's up late in September...for WBAL 11 up the road in Charm City! Near-term, Kim Martucci's wedding is this weekend,or so I believe, & Howard Bernstein et al have been filling in for her. Kim will likely be out for two or so weeks, while I don't know if a replacement for Pann will be forthcoming this fall.

Saw a gorgeous double rainbow just south of LaPlata this evening. One was starting to fade and the other was remarkably brilliant. Too cool!
