8:25 p.m. - Strong to severe storms lingering south and southeast of the Beltway
While much of the region is now in the clear, strong storms are still sweeping south and east through lower Southern Maryland. Meanwhile another cluster of storms has triggered a severe thunderstorm warning until 9 p.m. well south of the Beltway, in southern Prince William and northern Stafford counties, including I-95 from Dale City to Aquia Harbour.
6:55 p.m. - Severe storms moving into D.C.'s northeastern and eastern suburbs
Severe storms have reached I-95 between D.C. and Baltimore as they continue to track steadily to the east. A new severe thunderstorm warning has been issued for a large portion of the area from the District east to the Chesapeake Bay until 7:45 p.m. These storms are capable of damaging wind gusts to 60 mph and quarter-size hail, along with torrential rain and dangerous lightning.
6:25 p.m. - Storm warning added for southern Montgomery, northern Prince George’s counties, includes northern part of District
Storms continue pressing through areas mainly north of the District, hitting Montgomery County hardest where there have been reports of small hail and some downed trees from strong winds.
The National Weather Service add a severe thunderstorm warning for southern Montgomery County, the northern part of the District and northern Prince George’s County through 7 p.m.
In addition to pockets of hail and strong winds, these storms are producing very heavy rain.
6:10 p.m - Storms marching through D.C.'s northern suburbs
Radar shows several individual storm cells have consolidated into a line from near Leesburg to Germantown and into southern Carroll County. This line will pass through much of Montgomery and Howard counties over the next hour.
The storms are likely to produce very heavy rain, gusty winds and some areas of small hail and will be most intense in northern Montgomery and Howard counties, under a severe thunderstorm warning until 7 p.m.
Likely reaching the Interstate 95 corridor between D.C. and Baltimore around 7p.m., it’s possible these storms expand south and clip northern Fairfax County and the District as well as northern Prince George’s County.
As we get closer to sunset, we do gradually expect these storms to gradually weaken.
5:35 p.m. - Intense storms converging on northern Montgomery County
Two thunderstorm cells, both which have produced hail, are descending on northern Montgomery County, where they may merge. A severe thunderstorm warning is in effect for northern Loudoun, southern Frederick (Md.) and northern Montgomery counties until 6:15 p.m. Earlier these storms passed through Charles Town, W. Va., and Frederick (Md.).
In addition to very heavy rain and lightning, these storms are likely to produce hail and possibly damaging wind gusts.
Original forecast posted at 4 p.m.
Highs mainly reached the mid-80s across the area. Coupled with humidity that’s still on the lower side for the date, plus a lot of clouds, the day ended up rather bearable as far as late June goes. However, with a frontal zone draped across the broader region and a disturbance passing by, some showers and storms that dotted the landscape this afternoon will continue to do so this evening. Most of these storms will remain below severe limits, but small hail and a few damaging wind gusts might be possible.
Through tonight: Widely scattered showers or storms will roam through the area until about an hour after sunset, when they will dissipate. Most spots will stay dry, but those that get hit might see a quick punch of heavy rain and lightning, plus perhaps some strong winds or hail. Otherwise, it will be mostly clear through the night with lows in the 60s.
