Low pressure tracked east from Ohio, crossing Pennsylvania during the afternoon on Saturday, March 6th. Heavy snow fell across the northern counties and across the higher elevations of south central PA. Temperatures were critical for this event and, in most cases, some elevation was needed to have heavy snow accumulation. Up to a foot fell at Laurel Summit in Somerset County. Across the northern mountains, 6 to 8 inches was typical from Warren east to Coudersport. Some moisture from Lake Erie may have added a couple of inches to totals across the northern mountains late in the storm.
