Cold Weather- Philly Weekend Weather Forecast

GFS Forecast Map Saturday morning
GFS Forecast Map Saturday morning

An anomalously sharp jet stream dip for late March will bring cold weather to our area again this weekend, especially noticeable on Saturday.  Low pressure developing off the coast, will be too far east to affect us.

For Saturday, the high pressure system moving in with this upper trough will bring dry, breezy conditions, but instability clouds will result in partly/cloudy partly sunny skies.   MOS  are predicting temps to be about 45, but I’m thinking it will be colder,  in the lower 40s.  (Average high is about 57 degrees.)

Update Fri PM: Temps will be colder, about 40, and it will be windy on Saturday.

Sunny skies for Sunday, less wind and a bit milder, but still below average.  Winds swing around to the SW late in the day.  Highs will still be about 46.
