When does the D.C. area typically see it's first snow?
Areas of snow fell across the northern portions of our viewing area today but the D.C. Metro has seen nothing but rain. When can residents closer in to the city be able to get in on the action? No worries, it's already November 27th, so the region is only a couple weeks away from it's average first snowfall.
Checking the National Weather Service's NOWData page, you can get all kinds of information about the first and last dates as far as snowfall and temperatures. I narrowed it down to information about the first date the Washington Area sees it's first 0.1" of snow and first 1" of snow.
For the D.C. area:
The first 0.1" or greater amount of snow from the 1981-2010 period usually came around December 18th.
The first 1" of snow usually fell around December 29th.
For areas closer to Dulles:
The first 0.1" of snow comes a little earlier, around December 14th.
The first 1" of snow usually occurs a couple of days earlier around December 26th.
