Since I’ve lived in both DC and New York City, I followed the evolution of the big snowstorm this weekend with much interest. Here are a few posts with fantastic images and a great description of the weather behind the storm.
The Huffington Post has a stunning collection of photos of the blizzard taken from space here.
The Weather Channel has a series of photos from around the area here.
The Capital Weather Gang from the Washington Post has a detailed description of the evolution of the storm here.

And finally, a satellite view of the snow cover across the Northeast. Note the sharp edges of the snow line, which is one of the reasons why snow forecasting can be so difficult.
