49 out of the 50 states currently have snow on the ground –  yes, even Hawaii, where snow falls in Mauna Loa and Mauna Kea all winter.

Here’s how the snow forecast breaks down for some major cities:

Washington DC: 2-4 inches
Philadelphia, Pennsylvania: 4-6 inches
New York, N.Y.: 6-12 inches
Hartford, Connecticut: 15-20 inches
Boston, Massachusetts: 12-16 inches

The snow and cold started early this winter and has been extreme for most of the country.  Usually the Southeast avoids the blast, but not in 2011.  Below you can see maps of snow density and precipitation over the last 24 hours:
