PM Update: Untreated roads could refreeze overnight, Arctic chill on Wednesday

After a long, hectic, and sometimes treacherous morning commute with up to 4 inches of snow in some northern suburbs, the sun is shining bright on Tuesday afternoon. Light, fluffy snow that accumulated this morning has turned to wet slush on many secondary roads and sidewalks this afternoon. Our concern is now the potential for slush and water to refreeze on untreated roads tonight. Given the risk for refreezing, slow speeds and plenty of room is advised for the morning commute on Wednesday.

Through Tonight: After clear skies in the evening hours, clouds build back in. Between the sub-freezing temperatures and gusty winds, untreated pavement has a good chance of icing over, which could lead to another slippery commute on Wednesday. Lows bottom out around 20 degrees in the city, and the mid-to-upper teens in the cooler suburbs. A west wind starts to crank this evening, gusting to 25 mph and leading to brutal wind chills.

Tomorrow (Wednesday): Some untreated roadways will have frozen again the overnight hours, which could make the morning commute tricky in places. Temperatures will climb into the mid-20s in the early afternoon, but will begin to fall back into the low 20s soon after that. Clouds decrease through the day, and theres a chance of some flurries in the afternoon, with the highest chance north and northwest of D.C. Northwest winds whip at 20 to 30 mph, with gusts up to 40 mph, making the air temperature feel much colder than it actually is.
