Philadelphia Weather Outlook

ANOTHER BRIEF RETURN TO WINTER

A low pressure system will move in Wednesday afternoon with moderate rain (~1 “) and a  strong cold front will move through later Wednesday night with the jet stream plunging southward from a push of cold air—

Canadian GEM Regional model forecast 10 PM Thursday.  Red line is the 1000-500mb thickness line,  a rough approximation for the jet position and often considered the ‘rain-snow line’.  (Click on image for a larger view.)

 

This very strong cold front may bring some ‘interesting weather’ as it moves through and I’ll be keeping an eye on it.

Much colder temperatures later Thursday through early Saturday.  We may even see some snow flurries Thursday night.  Cold, windy conditions Thursday through Friday!   High temperatures in the low to mid 40s Friday and temps may fall into the upper 20s Friday night.   Still chilly on Saturday, although the afternoon should warm up a bit more.

Things  moderate further on Easter Sunday and next week looks milder and more tranquil.
