Though it’s been anything but a sunny day around here, showers have largely been stuck to the northwest of the immediate D.C. area. A cold front approaching the region will finally start to push showers across the whole region as we head into evening. By the time they end late tonight, cooler air will be taking up residence.
Through Tonight: The main body of showers (maybe a rumble?) begins to move east this evening. You may see a brief raindrop or two prior, but the brunt should hold off till around and after dark. In D.C., it might be more like late evening when the main shield moves in, and a little longer for places to the east. Showers then remain possible for a good portion of the night, but they should be gone by sunrise most spots. After the front passes near midnight, a period of strong northwest winds is likely, sustained around 15-20 mph with gusts past 30 mph. With that cooler air filtering in, morning lows make the low 40s in the colder spots to the mid-or-upper 40s downtown. Overall, rainfall isn’t terribly heavy, but some spots end up with about one to two tenths of an inch.
Tomorrow (Tuesday): This is one of those days where temperatures don’t rise much, and many spots may end up with highs around midnight (tonight) rather than during the day. Good news: Sunshine should make a strong appearance after any morning clouds and slight shower risk move off to the east. Despite plenty of sun in the midday and afternoon, highs only rise to around 50. Northwest winds also blow around 10 mph sustained, with higher gusts.
Midwest and Plains snow: A number of Midwest cities have neared or surpassed snowless streak records: including Chicago, Il. (where flakes were in the air today), Des Moines, Ia., Milwaukee, Wi., and Omaha, Ne. Further south, light snow fell across parts of Oklahoma and Texas last night, like around Dallas, Tx. where a dusting or a little more was reported.
