A Winter Storm Watch is in effect along and west of the I-81 corridor, while residents of the D.C. area should keep an eye on temperatures to see what kind of snow and slush is headed our way.

Today: Partly cloudy and cold.

Temperatures: 35°-39° | Wind: NEN 5-10

Tonight: Snow, sleet, freezing rain around 10 pm to all rain Saturday morning

Lows: 27°-34° | Accumulation: up to 1" slushy mix ( 1"-3" watch area)

Tomorrow: Mix to all rain except far N and W

Highs: Upper 30s| Accumulation: Slush will melt

Today will be partly cloudy and pleasant...just a bit on the cold side. Tonight will not be pleasant, however.

A storm system will bring a wintry mix a snow, sleet and freezing rain beginning around 10 p.m. The area with the highest risk of enough snow, sleet and freezing rain to cause widespread hazardous driving will be far north and west of Washington.

In the metropolitan area, surface temperatures will be critical. While a slushy accumulation of 1/2 to 1 inch is possible, temperatures will determine the actual accumulation and most importantly, determine the extent of any hazards to drivers. Stay in close touch with our updated forecasts on air, online and on WTOP radio.

During the day tomorrow, most of the region will see plain, old-fashioned rain as temperatures will be safely above freezing. In the watch area,  enough cold air could linger at ground level to prolong the icy mix.

Sunday will be damp, chilly and drizzly. Monday will be much warmer but more rain is forecast across the area.
