Philadelphia Winter Weather - Wed 12PM
The latest NAM model cranks out over 1 inch of precipitation as snow for Philadelphia. IF the NAM is correct, and if surface temps get as low as forecast, there's the potential for as much as 6-10 inches. Difficult to tell how much melting will occur on streets vs grassy surfaces or when temps will fall to freezing, but a significant snowfall of 6-10 inches is possible, not likely. More likely is considerable melting and about 2-5 inches.
Meanwhile, the GFS has backed off precipitation considerably, to only 0.3 inches water resulting in only an inch or two accumulation. With such large model differences, the confidence in this forecast is below average. Interesting differences-- will watch and we'll find out! :-)
