Only a day after posting that the deterministic GFS and NAM models have the snow well to our east missing us, today’s models GFS and NAM have jumped onto the snow bandwagon with the statistical models with the light snow occurring before daybreak on Saturday and  continuing during the daytime hours.  Currently the NAM is showing 2-3 inches in PHL!

The statistical models have been consistently predicting light snow in NJ and extreme SE Pennsylvania for several days.  Interestingly, the statistical models have reduce the probability just as the GFS and NAM show increased amounts of snow.

It now appears that the  coastal low pressure system will intensify enough to throw snow back into our area through the day Saturday; the snow will be light in PHL with somewhat heavier accumulations in NJ.    The NAM now shows 2-3 inches in PHL.   The GFS shows 3-4 inches with heavier amounts in NJ!  I expect the predicted amounts to change by Saturday.
