For South Central & Southeastern Pennsylvania rain will be the primary precipitation type but here too we need to watch weather models cautiously over the next 2 days given the strong upper air dynamics that will be making some cold air overhead.

The map above shows the European cutting off the upper low at 500 mb (18,000 ft). If this happens and it is a big if...then yes you probably will see a change over to snow as cold air collapses with the strong upper air dynamics. This process begins Friday morning as the temperatures at 5000 feet begin to drop to below freezing....READ MORE AT METEOROLOGISTJOECIOFFI.COM
