9:25 p.m. update: Tonight’s batch of storms is moving off to the east. So far, we haven’t seen much in the way of damage reports, but this activity did roll by after dark. The risk of severe weather should be done for the night. A new round of showers and sub-severe storms may begin to develop as soon as early morning, but more recent models have pushed the start time of that back a bit into the day. See forecast details below.

From 4:55 p.m... See bottom for earlier storm updates.

In our summer of never-ending 90s, today’s — the 51st such instance — might be the last for a while (fingers crossed!). As with most changes from hot and muggy to cooler, a chance of showers and storms is around through the evening. Then there’s a better chance of rain across the area tomorrow as the front passes the region. It’s all setting up what looks like a delightful weekend.

Through tonight: We’ll keep an eye out for storm development the next few hours. For now, it seems the worst may stay south of the area, but a storm risk continues through the evening. In the hours past sunset, the risk wanes and skies become partly to mostly cloudy but probably trend cloudier with time. Showers become increasingly likely as we get toward sunrise. Lows range from near-70 to the mid-70s. Winds are from the northeast around 5 to 10 mph.

Tomorrow (Friday): It’s gray and increasingly damp to start. Off-and-on showers a good chunk of the day help get a real change underway. It might be a bit of a shock as temperatures struggle to rise out of the 70s under mostly cloudy skies. If there’s enough rain around, we probably do get stuck in the 70s. If not, perhaps upper 70s and lower 80s for highs. Humidity remains moderate, but it’s dropping over time. Some clearing is possible by the evening.

...EARLIER STORM UPDATES...

8:57 p.m. update: The storm moving by to the north of the Beltway has been consistently producing a strong wind signature on radar. It seems likely that some wind damage is occurring with it.

8:27 p.m. update: A severe thunderstorm warning has been issued for parts of Montgomery, Howard, Anne Arundel, and Prince Georges counties until 9:15 p.m. This is mainly for the potential of winds to around 60 mph, which could cause damage.

7:44 p.m. update: Storms continue to march slowly east across west and northwest parts of the area. A new warning includes Leesburg and surrounding parts of Loudoun County until 8:15 p.m., due to the potential of damaging winds. For now this batch seems to want to focus on the northern half of the area as it shifts eastward.

7:10 p.m. update: We can’t seem to get through a day without storms. As such, we’re watching a broken line move in this evening. Several severe thunderstorm warnings have been issued, mainly to our northwest so far. In addition to heavy rain and lightning, these storms may produce isolated damaging winds.

Right now the worst of the storms nearby are to the north of Leesburg and east of Frederick. These line will continue to move east across the area over the next several hours.
