Just made this map of snow depths from last night/this morning around western PA from the responses I got. Wish I knew more about GIS because I think this would be cool to do with Facebook, Twitter, etc. I’m sure someone is already doing it, though. The “hours ago” is calculated from about 1:30PM Tuesday afternoon. Obviously if this became an operational application, there would be certain issues with people lying, inaccuracies, etc. But the idea is cool to give a general idea of how much snow certain regions have outside of actual weather stations, COCORAHS, Co-Op Observers, trained spotters, department of highways, etc. That is all
