Philly Weekend Weather Forecast

The cold upper level trough retreats to the north as high pressure builds in, allowing winds to shift from northwest to southwest by Sunday.

Saturday remains cold.  Some mid level clouds early, then mostly sunny, the some clouds late afternoon.  High 42.

A strong southwesterly wind brings mild temperatures and sunny skies Sunday.  It will be breezy.  High about 55.

As mentioned earlier this week, model continuity remains poor, so forecast specifics remain uncertain beyond a few days out.  One forecast aspect seems to have consistency — expect large swings in temperatures every few days. 

Winter Weather Outlook

The models had some trouble with today’s forecast and the general impression has been that the specifics of the coming week’s forecast details are somwhat low confidence.

That said, a deep low pressure is expected to move up the Appalachians giving us heavy rains and warm temperatures on Wednesday.  A cold front moves through Thursday and another very cold Arctic outbreak is in store for next weekend.

With the Arctic airmass in place, an Alberta clipper and another low pressure system brings another chance of snow  late next weekend into next week.
