Winter Weather Advisory 11 p.m. tonight through 10 a.m. tomorrow
A cold wind from the north has caused temperatures to fall into the low 30s. Overnight, as one area of low pressure passes to our north and west, and another develops to our south, a wintry mix of sleet and freezing rain is likely across large parts of the area.
The impact on travelers will be minimized because 1) most of the precipitation will fall after midnight and before mid-morning tomorrow when few people will be on the roads, and 2) near-freezing overnight temperatures should rise above freezing early-to-mid morning tomorrow, changing any lingering precipitation to plain rain (especially in the District and south and east).

From the National Weather Service's Advisory Statement:
WHILE ICE AND SLEET ACCUMULATIONS ARE EXPECTED TO BE MINOR...THE MIXED PRECIPITATION MAY CAUSE SIGNIFICANT INCONVENIENCES.
PRECIPITATION IS EXPECTED TO CHANGE TO RAIN TOMORROW MORNING... ESPECIALLY NEAR THE CAPITAL BELTWAY. PRECIPITATION WILL MOVE EAST OF THE REGION BY 10 AM.
A WINTER WEATHER ADVISORY MEANS THAT PERIODS OF SNOW...SLEET...OR FREEZING RAIN WILL CAUSE TRAVEL DIFFICULTIES. BE PREPARED FOR SLIPPERY ROADS AND LIMITED VISIBILITIES...AND USE CAUTION WHILE DRIVING.
Be especially careful on ramps, bridges, and overpasses if you're out late tonight or very early tomorrow.
