After lows dipping below zero in parts of the region early this morning, temperatures bounced back into the 20s this afternoon as a few snow flurries zipped across the region. A reinforcing shot of bitter cold air streams into the region tonight, bringing a new round of subzero wind chills by morning. Temperatures struggle to reach 20 on Friday.

Through Tonight: Scattered snow flurries early on, mainly north of the District. Then it becomes mostly clear and extremely cold. Lows range from the mid-single digits in the colder suburbs to the low teens downtown. Winds are from the north at 10-15 mph. The combination of wind and cold drops wind chills below zero this evening (between 9 p.m. and midnight) in our colder suburbs and around dawn downtown.  Some of our colder suburbs could see wind chills bottom out in the -5 to -10 range.

Tomorrow (Friday): The sunshine is brilliant, but the temperatures are brutal. Highs range from 16 to 21 (northwest to southeast), with wind chills near or below zero in the morning, “warming” into the single digits during the afternoon. Winds are from the north around 10 mph.
