7:30 p.m. — Strong to severe storms entering southern Md., western parts of area
Our next round of showers and thunderstorms is on the doorstep, with the greatest short-term risk of bad weather over southern Maryland.
Several rotating thunderstorms have been roaming north of Richmond the past few hours. This activity is the main threat for severe weather from this batch. It will approach the La Plata area over the next hour and continue to shift northeast from there. These storms have produced at least one tornado, near Hanover, Va., and another quick tornado or two remain possible.
To the west of the isolated storms. a line of showers and storms from Winchester to Charlottesville marches eastward. A severe storm warning was in effect for Winchester and surrounds until 8:15 p.m. While the immediate area may see some showers the next hour or two, this stuff is still several hours away from the I-95 corridor. Isolated damaging wind is possible with this activity in the short term.
5:55 p.m. — Severe thunderstorm watch until 10 p.m. from the District south
Storms are developing in west central Virginia and, as they are expected to head northeastward, much of central, eastern and northern Virginia as well as the District and southern Maryland, have been placed under a severe thunderstorm watch.

Storms that move through this area have the potential to produce damaging winds, hail and perhaps a tornado or two. Model projections suggest storms will reach Washington’s southwest suburbs between 7 and 9 p.m., and the Beltway area and locations to the east between 8 and 11 p.m.
Storms may weaken some, especially as they push north and northeast of the District. The watch includes the District and Fairfax, Prince George’s and Anne Arundel counties, but not areas to their north.
Remember that a severe thunderstorm watch means conditions may support severe storms but are not a guarantee. Stay alert. If a severe thunderstorm warning, on the other hand, is issued for your location, seek shelter.
It was a rather tranquil day, as long as you ignore the midday storms and tornado warnings. That batch of rain brought the region about a quarter of an inch, with some spots receiving a bit more. Thus far, there have been a number of wind damage reports in the area, but no confirmations of tornadoes. While what’s left to come shouldn’t be too crazy, we’ve still got some weather hazards ahead into evening.
Through Tonight: Additional showers and storms are possible this evening, perhaps through about midnight. If you come across flooding, remember to “turn around, don’t drown.” The big storm risk has waned, but an isolated severe storm isn’t impossible. Otherwise, skies are tending to clear. Temperatures fall to a 60-to-65-degree range for lows in most spots. There could be some patchy fog, although light west winds should help keep it minimal.
Tomorrow (Saturday): Bad weather is out of here in time for the holiday weekend. Skies are mostly sunny, with clouds most numerous through the midday and afternoon. We may see a few showers or a quick storm pop late, but they should be hit-or-miss if so. High temperatures are around 80. Winds are out of the northwest around 10 mph, with gusts past 20 mph.
Sunday: This one’s looking like a winner. We’re on the warm end with the “Nice Day” declaration (temperatures 65 to 85), but I’d imagine it’s coming if the forecast holds. Readings rise to around 85 for highs. Winds are light from the west and southwest.
Memorial Day: A pretty classic Memorial Day is on tap. At least when it comes to the unofficial-start-of-summer thing. Highs are near 90. With winds out of the south, humidity is on the moderate but sticky side.
