The unofficial end of summer – Labor Day weekend – concludes in summer-like style with toasty conditions and daily storm opportunities. The best chance of storms is on Labor Day itself.
Through Tonight: No weather concerns whatsoever. It’s partly cloudy to mostly clear, and a bit humid. Overnight lows range from the low 70s downtown to the upper 60s in the cooler suburbs. Light winds from the south at 5-10 mph.
Saturday through Sunday: Both days are partly to mostly cloudy, very warm and humid, with a 30-40 percent chance of afternoon and evening showers and storms. On Saturday, the highest rain chances are north and west of the District. On Sunday, the chances are pretty uniform throughout the region.
To be sure, it’s dry most of the time for outdoor activities, but with dew points in the sticky upper 60s and 70s (Sunday), you’ll want to take it easy. High both weekend days are in the mid-to-upper 80s. Sunday morning’s low temperatures range from 70-75 (suburbs-city). Winds tend to be from the south around 10 mph.
Labor Day (Monday): Very warm and humid with a 50 percent chance of afternoon and evening showers/storms thanks to an approaching fall-like front. Highs are again in the mid-to-upper 80s.
Pollen: Tree counts are LOW, grasses are MODERATE, weeds are MODERATE-HIGH, mold spores are LOW-MODERATE.
