Discussion and Forecast.
A Series of weak Clipper systems will be moving through the region during today and once again on Saturday. This first system will bring a period of Light snow and Flurries, mainly during this afternoon and into the early evening hours tonight. It looks like areas near and south of PHL, into Northern DE and Southern NJ, will have the best chance for periods of Light snow today. A coating to near 1" of snow accumulation can be expected for near PHL including much of Northern DE and Southern NJ.
Areas to the north and west of PHL will see mainly flurries with some spots seeing a light coating there. The timing: Periods of light snow should be moving in between 11:00 AM and 2:00 PM this afternoon and ending by 7:00 PM this evening.
A second Clipper will track further north tomorrow, across PA and to near NYC. This clipper will bring a few periods of light snow and flurries, mainly to our northern section, or from PHL and points north into the Lehigh Valley and Pocono's. Areas south of PHL will just see a few flurries during Saturday afternoon with little or no accumulations, while areas north of PHL could see a coating to near 1". High temperatures both today and Saturday will be in the mid 30's and lows in the lower to mid 20's.
Both Sunday and Monday should be dry with P.Sunny days and fair cold nights. Continued cold with Highs in the Mid 30's and lows near 20.
Next week things get very interesting once again for a possible significant winter storm. A storm system will develop over the southern Rockies and Southern Plains on Monday, then move East to the lower TN Valley by Tuesday night. Well ahead of this system, some accumulating snow will spread into the Delaware Valley later Tuesday and Tuesday night.
The track of this storm is still uncertain, but it appears a more northern track into the lower OH Valley then off the Northern M/A coast on Wednesday looks most likely. With this storm track being further north, some milder air aloft will likely change the snow to Sleet/Freezing rain, and possibly some rain on Wednesday. If the storm should track further south to the VA coast, We would remain mostly snow and some sleet into Wednesday, so stay tuned for a more detailed update on Sunday or Monday with this midweek storm threat.
