A Winter Storm Watch is in effect for the D.C. area late tonight through Tuesday early afternoon.

This Afternoon:
Cloudy and Cool
Highs: Mid-Upper 30s
Wind: S 5
Cloudy with Rain/Snow by Dawn
Lows: Upper 20s to Lower 30s
Precipitation: 30%
Highs: Low 30s
Snow: 90%

Just as we wind down from today' icy start, another batch of winter weather threatens. The National Weather Service has put us under a Winter Storm Watch for the potential of 5" or more of snow on Tuesday. 



I want to emphasize the "potential" part of this.  While I am confident that we will see snow in D.C. tomorrow, just how much is still in question.  Let's start with what is happening now.  The rain and freezing rain has ended and temperatures are very slow to rise. We should get into the mid to upper 30s this afternoon.  Tonight, a cold front and an area of low pressure will be approaching.  We will likely start to see precipitation by dawn.  It may start as a rain/snow mix or sleet before changing over all to snow.  The greatest window of opportunity for snow in D.C. will be from about 8a-2p.  A heavy snow band will likely set up somewhere, we just don't know exactly where.  That heavier band is the most likely place to get higher snowfall totals, but I think 1-3" is more likely for the majority of our area.
