Snow Advisory Tomorrow
Steve Scolnik @ 5:50 PM
**Snow Advisory in effect from 7 AM to 7 PM Wednesday**
Now
Sunny, windy, cold. Sunny skies, brisk northwesterly winds, and temperatures barely reaching freezing are setting the stage today for another whirl of the wonderful Washington winter weather wheel. The air is also extremely dry, with dewpoints generally below 0° (relative humidity around 20%). A "clipper" weather system now over the Great Lakes will be diving southeastward, bringing some snow to the Mid Atlantic area tomorrow. The latest model runs this afternoon continue to show that temperatures will be cold enough for snow, but that precipitation amounts are likely to be fairly light. For the metro area, that translates into 1-2" being the most probable amount, although one model does push slightly heavier amounts closer to the area.
Today's highs were 33° at National, 32° at Dulles, 31° at BWI.

Tonight and Tomorrow
Increasing clouds, cold, light snow developing. Clouds will increase overnight with lows in the low 20s in town to the upper teens in the 'burbs. Some light snow is likely to develop by dawn with some periods of moderate snow possible during the day and highs around 28-32°. Accumulations in the immediate metro area are likely to be 1-2".For the details of the Snow Lover's Crystal Ball, scroll down to Matt's post below.
