Winter Storm Warning through 12 p.m. tomorrow for Loudoun and Montgomery counties and N&W (until 6 p.m. Wed for Frederick County)
Winter Weather Advisory through 12 p.m. tomorrow for the rest of the metro area
Except in our northern suburbs, snow is now mixing with or has changed to sleet and freezing rain. In areas where it is no longer snowing, little additional snow accumulation is expected. However, icing will be a significant hazard overnight. Temperatures are presently in the upper 20s and will remain steady for the next several hours as steady sleet and freezing rain accumulate on tree limbs, power lines and untreated surfaces. Be extremely cautious driving on untreated surfaces as well as bridges, overpasses, and ramps. Pedestrians should also be very careful.
This Evening: Light to moderate freezing rain and sleet is likely across most of the area. Snow may mix in with the ice, but little additional snow accumulation is expected except in northern Montgomery County and to the north and west, where an inch or so of snow may accumulate before precipitation changes to ice.
After Midnight: Ice will remain the story -- as surface temperature only slowly rise toward freezing -- though areas south and east of D.C. may switch to plain rain. For D.C. and points north and west, the change to plain rain may not happen until morning. Some significant icing is possible in these areas -- perhaps bringing about a treacherous morning commute.
Tomorrow (Wednesday): Some morning ice -- which could make for a troublesome commute -- should give way to plain rain as temperatures rise above freezing between approximately 6 a.m. and 9 a.m. Much of the day may be characterized by light and spotty showers as temperatures rise to near 40. But a cold front will sweep through during the afternoon or evening, bringing with it possibly intense rain showers.
Behind the front, temperatures will once again drop below freezing late Wednesday night, so any water left on roadways may become icy again.
