Temperatures warmed a bit more than expected today, to highs near normal for this time of year. Plentiful sunshine along with light winds also came together to produce a pretty nice one as well. But when we factor in cold morning lows, today still finishes a bit below average. Conditions deteriorate heading through the evening and into the overnight, first with an increase in clouds, and then with light rain as well as some snow well to the north and west of D.C.

Through Tonight: Clouds are still a few hours off, but they’re on the increase as we head through the evening. By the time we get toward midnight and beyond, shower odds trend to likely across the area. For most of us, this should be a rain event, yet places well north and west of the city, particularly those with elevation could see a bit of snow as well. Some snow or sleet may even mix in closer to the city, but with temperatures above freezing, it won’t be an issue. Lows fall to near freezing in a few of the coldest locations, with most of the area making it to between the mid-30s and near 40.

Tomorrow (Tuesday): Light rain, with some moderate bursts, should continue during the morning, with rain tending to taper after noon. Any snow to the north and west, mainly in elevated areas west of Leesburg and Frederick or north near the Pa. state line, could also persist or change over to rain before ending. Grassy areas in higher spots might end up with a small dose of accumulation, but major worries are not expected. Showers may persist a few hours past lunch, particularly east of D.C. Everyone finishes with about .20-.40” of liquid, give or take a tenth of an inch or so. Highs should range from the upper 30s to mid-40s.
