Despite overcast conditions for the first time in more than a week, with the exception of southern Maryland, rain has mainly held off. And comfortable temperatures in the low 70s have generated few complaints. Rain chances increase as tonight wears on, with the possibility of some steady, heavier rains Wednesday.
Through Tonight: Through 10 p.m. or so, rain chances are fairly low (20-30%) with mainly sprinkles or light showers. After that, rain chances slowly increase to around 70% by dawn with the heaviest activity to the west and southwest. Overnight rain amounts may only total from around just over a trace to a quarter inch. Temperatures are mild, with lows 55-60.
Wednesday: Periods of rain are likely (80-90% chance), possibly moderate to heavy at times, especially west of town. Rainfall totals will probably range from 0.5-1.5” with isolated higher amounts. Some of the highest totals are likely in the western suburbs and especially towards the mountains where 2”+ can’t be ruled out. Clouds and rain hold high temperatures in the mid-to-upper 60s.
Pollen update from Walter Reed: Trees, grasses, and weeds are LOW. Mold spores are MODERATE.
