Until the middle of the afternoon, the region enjoyed clear skies, which boosted temperatures into the mid-50s. Some high clouds are starting to filter in, and they will gradually increase tonight. For Wednesday, both a warm front and cold front come through the area, bringing rain and cool temperatures.
Through Tonight: Clouds gradually lower and thicken, and it’s a bit chilly. We should have enough breaks in the cloud cover to see the International Space Station fly over the region between 7:27 and 7:30 p.m. tonight. Lows range from the mid-30s in the cooler suburbs to the upper 30s downtown. Winds are light from the southeast.
Wednesday: Rain is guaranteed, developing between 7 and 10 a.m. from southwest to northeast. It may be heavy at times between late morning and early afternoon, before a possible late afternoon lull. A cool wind from the east holds highs in the mid-to-upper 40s, although locations south of D.C. could spike a bit warmer into the 50s if the warm front moves through early enough. Rainfall amounts of a half inch or so are possible (with locally higher/lower amounts).
More showers are likely into Wednesday evening, and even a rumble of thunder.
Pollen update: Tree pollen is in the HIGH range at 445.05 grains/cubic meter and mold spores are LOW at 682.60 spores/cubic meter. (U.S. Army Allergen Extract Lab)
