Philadelphia Area Weather Forecasts

WEEKEND WEATHER FORECAST

#Philadelphia #weather #PAwx #PhillyWx

Posted Saturday 01/31/26 @ 12:16 PM — Currently there’s more sunshine than forecast but some high clouds are making their appearance and based on the latest RRFS, I expect to see more cloudiness by 4 PM. The RRFS is also forecasting more sunshine than clouds on Sunday.

The latest Water Vapor imagery shows the deep upper level cold air trough extending down to Florida and an elongated surface low developing off the South Carolina coast. (our snow storm that will pass us by.)

Current satellite water vapor image with superimposed RAP model 500-1000 mb thickness lines (yellow), Mean Sea Level Pressure isobars (black contours) potential vorticity (fine violet contours) with superimposed MRMS RADAR. Water Vapor Imagery reveals emitted water vapor infrared temperature, NOT reflected light from clouds as is the case with visible satellite imagery. (Click on image for a larger view.)

For those of you who were disappointed with our missing the snow on Sunday, the models are hinting at a light snowfall sometime Wednesday. We will be on the northern fringe of this potential storm. Stay tuned
