I don't know about actual satellite pictures, but here are snow cover maps drawn by NOAA since 2003 if you are looking to compare just recently: http://www.nohrsc.noaa.gov/nsa/

It's even cold in Key West. Key West is at 43 degrees right now (4AM). Its all time record low is 41.
It has so much more than meets the eye with layers and you can add all stations, just like the Weather Underground. It's even better in a lot of ways. Cold all over the place. Freezing all the way down to Homestead, FL, though still warmer in Miami.
