Snowfall from Dec 8th, 2013

Here's a snowfall map of reports we received at the NWS for the storm of the 8th of Dec, 2013.

The tight gradient along the Mason-Dixon Line was due to a very intense west-to-east band of snow which set up during the morning and early afternoon, producing 1-2" per hour rates.  Those rates are quite unusual.  As a note, the 7.5 inch report in West York is highly suspect, though, as a meteorologist from West York also sent a report of less than 5 inches.
