12:15 a.m.: The storm threat has ended for the night. Earlier storms brought a few scattered instances of downed trees and power outages in mainly northern parts of the area, including around Reston and Olney.
11:15 p.m.: Northern Montgomery, southern Frederick, Howard, and southern Carroll counties are getting the heaviest rain now. No warnings at the moment but those areas continue under a flood watch until 1 a.m.
10:25 p.m.: Like the first round of storms, the next round moving in from the west looks to focus on northern parts of the area. No warnings at the moment, but the storms are dumping heavy rain in Loudoun, Frederick, and western Montgomery counties as they advance east. Lots of lightning too.
9:40 p.m.: Radar is pretty quiet now right around the DMV. But more storms starting to approach from the west, now moving east into western Fauquier and Loudoun counties.
8:45 p.m.: The storms north and northeast of the Beltway have moved farther north, largely now out of Montgomery and Prince George‘s counties. These have been heavy rainers, including a report of 1.10 inches in 20 minutes according to the Maryland Mesonet.
8:15 pm: Here are some of the damage images we've seen go by. It seems parts of Reston got particularly hard it.
Storms are now mostly focused in Maryland, with at least a short break for much of northern Virginia and still dry in DC after being brushed earlier.
Lots of branches down. Fire dept. working with residents clearing some of the bigger ones. #vawx @capitalweather @WashingtonianWx https://t.co/wspJre77Jw pic.twitter.com/2drjoslKSr

7:40 pm: The biggest storm in the area continues to focus over northern and soon moving into northeastern suburbs. This storm has now produced a number of damage reports in northeast Montgomery County, including power lines downed recently near Brookeville. Laurel and Simpsonville are among those in line next.
Additional storms are developing along wind shift boundaries in and near DC, and more activity will cross the Blue Ridge into western parts of the area over the next hour.
