High pressure will again dominate Philly weather for this weekend, giving us fair skies and closer to average temperatures.
While much has been made of the chilly temperatures for Saturday, the actual expected high of 51 isn’t that far off from historical averages.
The dip in the jet stream giving us this cooler weather will relax by Sunday and temperatures will rebound to above average (60) by Sunday afternoon.
Truly cold weather has been conspicuously absent so far this Fall and the long range model forecasts don’t show much in the way of typical large latitude jet stream dips. So the general feeling is that truly cold weather may wait to make its appearance until late December or early January, just as it has over the past few years.
A large, sprawling area of high pressure will dominate this weekend and provide beautiful weather. A north to northwesterly flow will bring blue skies but temperatures will average above the average high of 57.
High temperatures on Saturday 60 and high 62 on Sunday.
The small dip in the jet stream that brought us the chilly weather today will relax and a return of a southwesterly flow at the surface and aloft on Saturday will bring mild temperatures and some cloudiness.
Saturday will start cloudy but clouds will break for a mix of sun and clouds later in the morning. A mix of sun and clouds is expected in the afternoon with a high of 66.
The mix of sun and clouds on Sunday. Very mild with a high of 72. Cloudiness increases late afternoon as a weak cold front moves through. Light showers after 5 pm.
