Overview: A line of strong to severe thunderstorms, with a history of hail and damaging wind, is fast approaching the metro region, and should pass through between 7:45 and 10 p.m. from west to east. A Severe Thunderstorm Watch is in effect through 11 p.m. has been cancelled.

9:25 p.m.: The strongest storms are now racing away from the immediate metro area to the southeast through Charles County and into Calvert and St. Mary’s counties. Moderate to heavy showers with some lightning mixed in remain behind those stronger storms, but shower and storm activity should diminish over the next hour or so (maybe lingering longer south of D.C.) and the potential for storng storms is dwindling.

9:00 p.m.: The line of strong storms from D.C. southward, which has produced several reports of small hail, has made it east of I-95 and is moving into central to southern P.G. County and Charles County. While there are no warnings issued for these storms (b/c they don’t meet the severe wind criteria), they are still impressive with strong winds near or over 50 mph along with small hail and dangerous lightning. Sit these ones out inside.

8:40 p.m.: The Severe Thunderstorm Warning for Fauquier County was allowed to expire and no other warnings are currently in effect. Still, the storms set to move from west to east through D.C. and points south over the next 45 minutes or so look quite potent with the potential for wind gusts near or over 50 mph, small hail and dangerous lightning.

8:25 p.m.: The strongest storm with the most lightning, and the only one triggering a warning for the moment, remains the one moving east through the southern two-thirds of Fauqier County (described in previous update) and into Prince William County. The northern part of that storm is trying to extend eastward, straddling I-66 at the moment and could work its way into D.C. and points south over the next half-hour. Northeast of there, weaker showers and storms are now touching the northwest branch of the Beltway and will push east and southeast across southern Montgomery County, Fairfax County and then D.C. over the next hour. Meanwhile, another area of storms has popped up southeast of the Beltway and is moving northward through P.G. County.

7:55 p.m.: A severe thunderstorm warning is in effect for the southern two thirds of Fauquier county through 8:30 p.m. Marble sized hail and winds to 60 mph are possible. Storms extend northeast and southwest of there, and may also produce lightning, small hail and strong winds. The storms are racing east at 50 mph and will move into eastern Loudoun county and western Montgomery county in the next half hour.
