To be sure, this second wave of storms, which consolidated into a solid line that swept through much of the area, was more intense and widespread than we anticipated or that models predicted. They produced quite a few reports of wind damage, including downed trees in Upper Marlboro, the District, Rosslyn, Chantilly, Loudoun County and Bethesda.
Here’s a map showing the preliminary reports of severe weather today, including both waves:

Original article from 7:05 p.m.
Morning clouds helped keep temperatures from rising quite as high as they could have today. Nonetheless, readings still topped 90 in most spots. The 92 at Dulles tied a record high for the date from 2007. Baltimore also reached 94, tying an old record. That high heat helped fuel scattered severe storms this afternoon. While the earlier line has moved off, there could still be an isolated strong to severe storm this evening. It’s looking a good deal quieter into tomorrow.
Through tonight: With earlier storms moving away to the east, anything else is rather hit-or-miss. A storm or two could be strong or severe this evening, though. Odds dwindle after that, but a shower is possible late. Lows are in the mid-60s to near 70. There could be a touch of fog late as humidity is slow to diminish.

Tomorrow (Thursday): We’ll see a lot of sun, especially early and late. There could be some increase in cloudiness during the day. Highs are in the mid- and upper 80s as humidity falls off compared to today. Winds are out of the northwest around 10 mph with higher gusts.
Pollen update: Tree pollen is moderate at 49.2 gains per cubic meter of air. Grass pollen is moderate/high, as are mold spores. Weed pollen is low.
