9:40 a.m. update: Rain is exiting the Beltway as the complex of heavy storms sweeps northeastward into Baltimore, which can expect torrential rain and strong winds over the next 30 to 45 minutes.
Even though the worst of the rain has ended in the metro area, standing water remains on some roads from runoff and overflowing streams. Remember not to cross a flooded road in your vehicle. Turn around, don’t drown.

FORECAST IN DETAIL
Lingering rain has some impacts this morning. Let’s consider it a way to work on ending our drought! At least we have a drier, calmer air mass trying to move in as the weekend progresses. It’s also kind of chilly.
Today (Friday): Rain, showers, thunderstorms may dominate our weather through early afternoon. Rain that fell most of last night should taper this morning. We may even see some sunnier times in the midday. Strong breezes from the south could gust between 20-30 mph. Muggy high temperatures should still get into the mid-to-upper 70s. Any storms later in the day may tend to be isolated, but they could be powerful with large hail, damaging wind, and a tornado all possible. Confidence: Medium
Tonight: Showers or storms may linger into the evening, but they dissipate with time. Ahhh — drier air enters the region, despite winds remaining out of the south-southwest — and gusty, around 20 mph at times. Skies should show some clearing so a few stars might be visible. Low temperatures may not dip too much, but 50s to near 60 (downtown) feels pretty good. Confidence: Medium
Tomorrow (Saturday): Southerly winds remain at it, again, blowing around 15-25 mph at times. Sunshine could be around earlier in the morning but clouds and shower chances look possible by late morning and into the afternoon. Don’t be too surprised if you even hear a rumble of thunder. High temperatures hold in the low-to-mid 60s. Confidence: Medium
Tomorrow night: Could be dry and partly cloudy, but let’s keep a small chance of a shower mentioned — especially in the early morning hours. As of now, looks like nothing major. Low temperatures may bottom out around 50 downtown, with 40s outside the Beltway. Confidence: Medium
A LOOK AHEAD
Sunday: Clouds could fight the sun a bit, but at least isolated shower chances stay low (below 20 percent chance). Fresh west-northwesterly breezes around 10-15 mph are possible. High temperatures could stay in the “fresh” range of near 60 to perhaps mid-60s if we see a bit more sunshine than currently expected. Confidence: Low-medium
Sunday night: Could finally be fairly clear, calm AND dry. Maybe get in that delayed stargazing with your telescope! Except bundle up a bit, low temperatures could dip as cold as the mid-30s in coldest spots, to perhaps mid-40s downtown. Check back in on Sunday for any possible frost/freeze watches north and west of town (slight chance). Confidence: Medium
60s and sunshine could dominate both Monday and Tuesday! Enjoy refreshing, slightly below-average temperatures this time of year. You may not even notice much chill, thanks to such a strong sun angle. Speaking of which, wear that sunscreen! Confidence: Medium-high
Expired updates from earlier this morning
8:45 a.m. update: The worst of this present activity is moving through the city over the next half hour or so. Torrential rainfall is occurring with the strongest part of this line, in addition to the risk of isolated wind damage. It’s a good time to wait it out indoors.
8:38 a.m. update: A severe thunderstorm warning is up for most of D.C. and the eastern portion of the area until 9:30 a.m. Damaging wind potential continues to be the main risk.

8:15 a.m. update: Despite the lack of much lightning with the activity moving through, it is packing quite a punch. Wind damage continues to be a risk over the southern suburbs in particular. Elsewhere, heavy rain continues as the back edge of the overnight storminess moves closer.
