The trend Monday night was for a track farther offshore with the European and the American GFS forecast models. This would mean the Delaware Valley would be on the very western edge of the precipitation shield; very little rainfall from Philadelphia on westward as dry air would be in place, but it would be colder. That would mean a chance for some wet snow, especially in the northern suburbs. Temperatures 5,000 feet aloft could be cold enough to support snow, but near the surface may be just too warm. The best shot for any accumulating snow would be in the higher elevations on Pennsylvania and New Jersey.
