WEEKEND WEATHER FORECAST

The beautiful weather will continue through early Sunday. High pressure maintains its hold through Saturday, but a southeasterly flow from a newly formed weak coastal low and a front to our northwest that loses its upper air support will bring a bit more humidity and some cloudiness for Sunday afternoon and evening. (The shore stays sunny, according to the RRFS.)

18z RRFS clouds/precip at 3 PM Sunday. Approaching front falls apart due to wide, diffuse and split jet streak aloft. (Click on image for a larger view.)

Showers originally expected for Sunday afternoon will likely fall apart as they approach Philadelphia due to a diffuse, broken jet streak.
