10:15 p.m. - Flash flood watch in effect through Friday afternoon

Despite a break in the showers and storms currently, more are expected later this evening and at times tomorrow. As a result, a flash flood watch is in effect for the D.C.-Baltimore region through Friday afternoon. Rain amounts of 1 to 3 inches in a short period of time are possible, which could lead to localized flash flooding.

8 p.m. - Severe thunderstorm warning east of D.C.

As showers and storms advance from the southwest across the District and into the northern and eastern suburbs, a severe thunderstorm warning is effect until 8:30 p.m. for a large area east of D.C. including Bowie, Upper Marlboro and Crofton. As with the earlier warning area, damaging wind gusts to near 60 mph are possible along with heavy rain and lightning.

7:25 p.m. - Severe thunderstorm warning from D.C. to the south

Showers and storms moving in from the south and west have prompted a severe thunderstorm warning from D.C. to the south until 8 p.m. If you are in the warning area, stay indoors if you can until then. Be careful if you must drive, as winds could gust to near 60 mph, potentially bringing down trees and branches.

With highs in the low and mid-90s, increased humidity today certainly made itself felt. Heat indexes were pushing near and past 100 in spots this afternoon ― lest we forget it was a record-smashing 28th day at or above 90 in D.C. this month, and fortunately probably the last. Baltimore reached its 25th day, now alone in the top spot all time for any month, like us here in the District. Clouds that quickly shrouded the sky this afternoon are the first sign of some real change to come in our weather, a big part of which is the widespread chance of rain.

Through tonight: A lot of rain is lined up to our west. How much it will make it here is still up for some debate. Isolated showers or storms early this evening will turn to a more widespread rain risk tonight. It could still end up a bit hit-or-miss, with the heaviest totals (perhaps past one inch) in any storms, especially if an area gets hit multiple times. A few storms could be strong to severe this evening, with damaging wind the main risk. Low to mid-70s should do it for lows in most spots.

Tomorrow (Friday): It will be cloudy and downright chilly — if you count chilly as temperatures not racing toward 90. A good chunk of the day we may be dealing with rain, although we’ll have to watch where the frontal boundary sets up. If it’s far enough south, we might not see a lot, as the heavy activity focuses south. In other scenarios, we could end up with enough for some flood risk, with another inch or more possible in spots. Believe it or not, highs might get stuck somewhere close to 80.

See ya, 90s: Our pattern is finally legitimately changing, at least for a while. With upper-level low pressure increasingly anchored to our west, we’ll likely see multiple rounds of rain ahead. The first is on our doorstep, and more seems a decent bet tomorrow. Though a good chunk of central Virginia in particular ranks from very dry to drought, the immediate area has seen a fair amount of rain in recent weeks. If the heavier rain does indeed target the local area, flooding may become an issue as soon as tonight or tomorrow.
