Washington, D.C. – A crisp December chill grips the capital region this morning as a developing winter system pushes toward the Mid-Atlantic, bringing the first measurable snow chance of the season. Forecasters say the D.C. metro will see rain mixing with snow between 7 a.m. and 10 a.m. Tuesday, possibly leaving a light coating to one inch on grassy or elevated surfaces.
According to the National Weather Service in Baltimore/Washington, precipitation will begin as light snow before changing to rain late morning as temperatures edge above freezing. Drivers along I-95, I-66, and the Beltway should prepare for wet, slick conditions and reduced visibility during the morning commute. Though major accumulation isn’t expected, even a slushy mix can make bridges and ramps treacherous.
Winds will stay light, but cold air behind the system will drop Tuesday night lows into the upper 20s, raising the risk of refreezing on untreated roads. By Wednesday, skies clear with highs near 41°F, ushering in a bright but brisk midweek stretch.
The region stays mostly dry through Friday, with another chance of rain or light snow returning late in the week as the next system approaches from the west.
Residents should monitor local alerts and allow extra time for morning travel. This quick-hitting system marks the beginning of true December weather across the capital — a reminder that winter’s pace is picking up.
