Forecast in detail Most of this winter has been relatively mild for the D.C. area and most of the Eastern U.S., but we're about to get our second significant cold blast of the season. We're just seasonably cold today and tomorrow before a cold blast lowers wind chills to the teens and single digits Friday and Saturday. No snow with this cold air, though, as temperatures moderate by Sunday afternoon. Today (Wednesday): Snow showers exit to the southeast early this morning. Temperatures could be cold enough north and west of the Beltway, in the upper 20s and low 30s, for some slick spots during the morning commute. Otherwise we should see skies turning partly to mostly sunny later this morning into the afternoon with highs only in the upper 30s to low 40s, plus a bit of a breeze at times from the northwest. Confidence: Medium-High Tonight: Evening temperatures drop off quickly through the 30s. With mostly clear skies and light winds, lows should bottom in the 20s area-wide, ranging from the low to mid-20s outside the Beltway to the upper 20s downtown. Confidence: High Follow us on Facebook, Twitter, and Instagram for the latest weather updates. Keep reading for the forecast through the weekend... Tomorrow (Thursday): Looks like a storm system stays mostly to our south, leaving us partly to mostly cloudy with only the chance of a light rain or snow shower south of town. Highs remain on the cool side, in the low to mid-40s with light winds. Confidence: Medium Tomorrow night: Still that chance of a light snow shower, mainly south of town, during the evening. The colder air is on its way, but hasn't arrived quite yet with lows in the upper 20s to low 30s. Confidence: Medium A look ahead Temperatures are headed nowhere fast on Friday despite partly to mostly sunny skies, remaining mostly steady through the day in the upper 20s to mid-30s with gusty winds. That means wind chills in the mid-teens to mid-20s as winds come from the northwest around 15-25 mph with gusts over 30 mph. Mostly clear and very cold Friday night with lows in the teens and a lingering breeze lowering wind chills to the single digits. Confidence: High  Forecast for Friday night shows wind chills dropping to the single digits. Some spots could see wind chills near zero. (National Weather Service) | Plenty of sunshine Saturday but cold, with highs only in the upper 20s to low 30s. Winds ease up a bit, but they're still breezy enough to keep wind chills from rising past the teens to low 20s. Partly to mostly cloudy Saturday night with lighter winds and lows in the upper teens to mid-20s. Confidence: Medium-High After a frigid start on Sunday, we'll take the edge off the chill with afternoon highs in the 40s as a light wind comes from the south. Can't rule out a light rain or snow shower under mostly cloudy skies. Confidence: Medium Snow potential index A daily assessment of the potential for at least 1 inch of snow in the next week, on a 0-10 scale. 1/10 (→): Plenty of cold air the next several days, but not a lot of moisture to work with. |
