Philly Weekend Weather- Late Afternoon Edition

An amplification in the jet stream will drop a cold front through our area late on Saturday.

Saturday starts with bright skies and possibly some sun very early, but clouds quickly move in by mid morning. By noon, it will be cloudy.  Both the NAM and GFS currently hold off the rain until 2-4PM (although some light spits possible before then.)   High temperatures about 54.   Moderate rain by evening and through the night.

Some showers still possible very early Sunday morning, then skies attempt to clear.  However, cold air aloft with the upper cyclonic flow will result in considerable broken stratocumulus cloudiness for much of Sunday.  It will be very windy and gusty on Sunday.  High 55 before the cold air moves in at the surface Sunday night.

(For Thanksgiving, the outlook is for below average temperatures – highs in the upper 40s. Looks mostly dry at this time, however, the statistical models are hinting at some light showers.)

I hope to be posting my Winter Outlook by the first week in December.
