Other than some wave clouds forming off the mountains and caused by daytime heating, it was a spectacular looking day. Of course, the strong winds and cool temperatures made it feel a little less perfect outside. Those gusts were indeed gusty, peaking at 37 mph in D.C. and 35 mph at Dulles. Grab a coat this evening and tonight, as we fall off highs in the mid-50s to near 60 and ultimately down into the 30s many spots.

Through Tonight: Much like today, it’s a pleasant but slightly chilly evening. Those gusty winds begin to wane, especially after sunset, yet we should still see 10-15 mph sustained and higher gusts into the night. Lows are mainly in the 33-40 zone, but a few spots could kiss freezing. Winds should minimize any frost concerns.

Tomorrow (Thursday): After a crisp morning, it’s a fairly nice day. Skies are partly to mostly sunny, and highs end up in the mid-to-upper 60s. Winds are considerably lighter than today as well, but still blow around 10 mph from the northwest. Gusts past 25 mph are possible.

Pollen update: Tree pollen came down a bit after yesterday’s shower activity, now at 622.04 grains/cubic meter, but still HIGH. We should be headed into peak anytime now. Grass pollen and mold spore counts are low.

Late April? It was another chilly day across the region behind yesterday’s cold front. Chilly enough that parts of Pennsylvania have reported snow today, along with midday temperatures in the mid-30s.
