FORECAST THROUGH THE WEEKEND

Through Tonight: Early this evening (before 6 p.m.), the passage of a pre-frontal trough brings some thunderstorms mainly to southern Maryland and the northern neck of Virginia. That starts the arrival of cooler and drier air. Then, the actual cold front comes through between 5 p.m. and 11 p.m. (from west to east), triggering some more scattered showers and storms (40-50 percent chance) with heavy rain and lightning. A few of these storms may contain damaging winds. After midnight, slow clearing begins. Overnight lows range from 63-70 (suburbs-city).

Saturday’s a great pool or beach day. While it’s very warm, with highs climbing into the upper 80s, humidity levels gradually drop to comfortable levels (dew points into the mid-to-upper 50s). We have a nice breeze from the north at around 10 mph to boot. Saturday night is mostly clear and pleasant, with lows 58-67 (suburbs-city).

Sunday’s not too shabby either. It’s partly to mostly sunny (some high clouds increase in the afternoon) and warm, with moderate humidity (dew points 60-65). Highs range from 85-90, with winds becoming from the south at 5-10 mph.
