This weekend may not live up to recent standards but it could certainly be worse. A nearby front means generally cloudy skies, with the best chance of showers tonight, and Sunday afternoon and evening.
Through Tonight: Rain focuses mostly east and southeast of I-95 this evening and may spread west over the immediate D.C. area, mainly after midnight. There’s likely to be a sharp western cutoff to the rain, so from around Warrenton to Frederick and points west, rain chances diminish. Overnight lows are mostly in the mid-60s with light winds. Rainfall potential ranges from around 0.5-1″ east of I-95, to 0.25-0.5″ in the immediate metro area, to 0.25″ or less in our far western suburbs.
Tomorrow (Saturday and Saturday night): Steady rain should be exiting to the northeast by dawn. The balance of Saturday should be dry though mostly cloudy. I’d say shower (with perhaps a rumble of thunder) chances – in the afternoon and evening – are only around 30 percent. Clouds keep temperatures cooler than average, with highs 76-81. Winds are from the northeast at 5-10 mph. It remains mostly cloudy Saturday night, with a 20 percent chance of showers/thundershowers, and lows 65-70.
Sunday: Remaining mostly cloudy but it wouldn’t shock me to see some intervals of sun in the morning into the afternoon hours. There’s a 50 percent chance of showers and thunderstorms in the afternoon into evening. It’s slightly warmer than Saturday, with highs into the low 80s and light winds from the south around 5 mph.
Pollen: Tree/grass/weed counts are LOW. Mold spores are LOW-MODERATE.
