The latest NAM and GFS model data from this morning has become available. The NAM maintains a QPF of about 0.24 inches water. The GFS, as it often does, has a lower QPF of 0.16 inches water, falling between 1 and 6 PM.
The higher resolution (but not necessarily more accurate) NAM has 0.16 QPF.
So we’re looking at 2 inches, possibly 3 inches of snow by the time it ends at around 6 PM. Ground surface temperatures are much lower than previous snowfalls, so expect some slippery conditions despite the low snow totals.
Earlier this week, the statistical models suggested a coastal storm brushing our area. That forecast fell apart over the past few days, but the latest model runs have the storm affecting NJ and the snow shield has expanded westward into Phladelphia . The latest NAM just available has a QPF over 0.24 inches water for PHL.
This afternoon’s GFS had somewhat less, but the trend has been towards higher QPF. So it looks like another light snow of 2-3 inches for Friday afternoon, ending early Friday evening .
Thurs 11 pm- Latest GFS model has a QPF of 0.26 inches water. Snow totals 3-4 inches ending early Friday evening.
