Muggy & mostly cloudy with rain showers ending this evening. Forecast turns warmer with plenty of sunshine through Memorial Day. Flash flood watch for the Eastern Panhandle has been set to expire this evening.

Surface front extending across the east will gradually pivot eastward today, weakening as it exits the area. Despite the limited sunshine today we can expect a generally dry forecast for much of this morning & into the afternoon. Few leftover rain showers & and isolated storm are still possible this evening before skies really dry out tonight into Saturday.

Temperatures will stay modest today. Lots of cloud cover will keep sunshine at a minimum. Highs will be in the upper 70s. Showers come to an end tonight, winds die down & allow for some patchy fog to develop into early Saturday. Expect lows in the low 60s overnight.

Upper level ridging will be just beginning to take hold over the Mid-Atlantic states Saturday morning. Plenty of sunshine will be on tap from Saturday, right through the first part of next week! Southerly air stream will start bringing much warmer, subtropical air into the area from the Gulf of Mexico. Highs will be in the upper 80s Saturday, then in the 90s Sunday. So we'll keep a slim chance of a few isolated thunder cells over the long weekend. Any storms would most likely fire up in the late afternoon/evening when daytime heating peaks. Otherwise, nights will be mild with lows in the mid 60s. Patchy river valley fog will settle in during the wee morning hours but will burn off very quickly.

Forecast will stay hot and dry for Memorial Day and into midweek next week. Cannot rule out an isolated storm, given that plenty of daytime heating would fuel convective thunderstorms. Still, chances for rain remain slim until perhaps Wednesday night/Thursday. Still too early to try to get fancy with forecast for late next week. So enjoy the holiday weekend!!
