PM Update: Cold front brings freshly chilled air

It was a beautiful day in its own right, but when you factor in what we’ve seen the past few it’s extra glorious (unless you’re a Nats fan). After some morning low clouds, we’ve seen plentiful sunshine across the area, and that helped temperatures reach the upper 60s to near 70 for highs. A cold front moving in from the west will put an end to our warm-up, but conditions should remain fairly peaceful regardless.

Through Tonight: Clouds increase to partly or mostly cloudy for a time as the cold front passes this evening into early overnight, but they shouldn’t amount to anything, and we’ll trend clearer again as the hours wear on. Fresh cool air promises a chilly one, with temperatures dipping to near 40 in the coldest spots while probably hanging closer to the upper 40s downtown. Northwest winds around 10-15 mph, with higher gusts early, should diminish around and after midnight.

Tomorrow (Thursday): It’s gonna be a bright (bright), bright (bright) sun-shiny day. But, also cooler than today by a noticeable amount. In fact, temperatures may struggle to get to 60 in some spots while perhaps heading into the low 60s in others. At least winds shouldn’t be a huge deal, as they’ll be light from the northwest and west.

Tropics: While the weather is pretty quiet across the U.S. today, a few areas of disturbed weather are wandering around in the Atlantic. One tropical wave east of the windward islands is the most organized of two areas, and the NHC gives it a 30% chance of becoming a tropical cyclone in the next 48 hours. The other wave near the Bahamas is expected to merge with a front moving east in the next few days.

Pollen update: Grass and weed pollen are both low. Mold spores are as well.
