A frontal system will move through our area Friday night into Saturday morning and slowly through NJ on Saturday afternoon.  Several days ago, it looked like there might be showers on Saturday in Philadelphia, but right now, it appears that skies will partly sunny  during the day.  Highs near 90 and humid.   Showers possible in PHL during the afternoon,  but most likely in NJ, especially eastward, at the shore.

Sunday will be mostly sunny and very warm.  High 90.  Much less humid.
