Wednesday brings season's first chance of light snow to D.C. region.
The chance of meaningful accumulation is low.
On Monday, temperatures in Washington are set to soar well into the 60s. But two days later, the region could see its first snowfall of the season (not counting the flurries last week).
A strong cold front will pass through the area late Monday, knocking temperatures back about 25 degrees by Tuesday. Then, on Wednesday, a weak storm system is expected to move in from the south with enough cold air in place for the chance of snow.
Computer models vary on the intensity of any potential snowfall, and temperatures (near to a little above freezing) will be only marginally cold enough to support frozen precipitation. In other words, the chance of accumulating snow is rather low but will increase some toward the mountains, especially along and west of Interstate 81.
