8:25 p.m. update: Showers and thunderstorms that produced frequent lightning and impacted mostly the southern part of the area have moved off to the south and east. A few additional showers and thundershowers linger to the west and northwest of the area and a few spots may see a shower in the next few hours. Anything additional should be isolated and less intense than earlier activity. Thus far, no reports of damage have trickled in.
7:45 p.m. update: A severe thunderstorm warning has been issued for southern PG, western Calvert, and southeastern Fairfax counties, in addition to surrounding areas. These storms moving across the southern postion of the area may contain hail and wind gusts to around 60 mph.
From 3:30 p.m.: A warm front pushing through the area has produced fairly cloudy skies, with some sunny breaks, following this morning’s showers and thunderstorms. Highs across the region are largely reaching the mid-60s to near 70, the coolest spots generally right near the water. A cold front now working toward us from the northwest gets hung up close by, providing more potential inclement weather tomorrow and beyond.
Through Tonight: Clouds stick around heading into the evening, and there could be a few showers (perhaps a rumble) around, mainly after dark into the overnight. Rainfall coverage should not be that widespread or intense, and many locations may stay dry. Otherwise, it’s mostly cloudy with lows reaching the mid-40s to near 50.
Tomorrow (Tuesday): Partly cloudy skies of the morning turn cloudier in the afternoon and evening as a front in the area tries to nudge back north. Much of the day should be pretty dry, though a few showers are possible by evening. Highs rise to near 60 or a bit above. Winds are light, mainly from the northwest around 5-10 mph, with some higher gusts.
West Coast storm: While we were treated to some thunder this morning to mark the beginning of spring, folks out west are dealing with the aftermath of record rainfall. The big winner as far as records go was Santa Barbara Airport where 5.23” of rain was recorded on Sunday -- a new daily and all-time daily record. Many other locations broke daily records, including Los Angeles, Burbank and Oxnard. Higher elevations, including the relatively low Grapevine pass have seen as much as 1-2’ of snow.
7:10 p.m. update: In addition to the big cluster of storms in Prince William and southern Fauquier counties, a small storm has developed from Fairfax city to near Burke and could produce some downpours and lightning in parts of central and southern Fairfax county over next 30 minutes or so before probably heading toward southern Prince George’s county.
6:50 p.m. update: A severe thunderstorm warning is in effect for extreme southern Fairfax county, southern Fauquier, Prince William & northen Stafford County until 7:45pm. Dangerous lightning, quarter sized hail and wind gusts to 60 mph possible with these storms - which should remain south of the beltway and the District. Storm should track toward Charles county by around 7:30-7:45 p.m.
5:45 p.m. update: A cluster of thunderstorms over northern West Virginia is entering western Virginia. Some of the activity may impact the outer west and southwest suburbs in another hour, including Loudoun (especially southern) and Fauquier counties. Heavy downpours, lightning, gusty winds and some small hail (not unlike the storms this morning) is possible with these storms. By between 7:30-8:00 p.m., these storms could clip the closer-in suburbs, with southern Fairfax county, the southern half of the District, southern Prince George’s county and points south most likely to be affected.
