WEEKEND WEATHER FORECAST

High pressure builds in for the weekend.

Saturday will be mostly sunny with periods of fair weather cumulus clouds at times.  It will be comfortably non-humid and cool with highs around 77.

Ordinarily, this would be a straightforward forecast, but this high pressure center will remain to our north and a northeasterly flow of air around the high can bring in some unexpected cloudiness, especially for Sunday. The GFS keeps the immediate PHL area relatively cloud-free for Sunday, but the NAM has cloudiness developing in the afternoon here.  High temps around 75.

So there’s uncertainty with the Sunday forecast.

Additionally, both models pull in clouds and light drizzle for the immediate Jersey shore late afternoon Sunday.  Not sure about that either.
