Relative to yesterday’s mid-70s, this afternoon’s low 60s felt a little nippy even if normal for the time of year. Temperatures edge even cooler Friday thanks to a gusty wind from the north. Frost and freeze concerns are limited to northern Maryland and the Shenandoah Valley tonight but extend closer in Friday night.
Through Tonight: Partly cloudy skies turn mostly clear, and temperatures steadily decline. Lows range from the low-to-mid 30s in the coldest suburbs (Loudoun and Frederick county) to 39-42 downtown. Winds are from the north around 5-10 mph. Freeze concerns are primarily in northern Maryland and the Shenandoah Valley.
Friday: It’s one of the cooler days in recent memory albeit partly to mostly sunny. A brisk wind from the north (at 10-15 mph, with some gusts to 20 mph) deals the region a March-like feel, with highs only in the mid-to-upper 50s. This chilly day paves the way for a cold night, with frost and freeze concerns drawing closer, perhaps into Fairfax and Montgomery counties. We expect some additional frost advisories and/or freeze warnings to be issued and will keep you posted.
Pollen: Counts are still way up there, trees are HIGH at 1213 grains per cubic meter - up from 1098 Wednesday.
