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.

 

An Alberta clipper will move through before daybreak Thursday.  QPF values range from 0.08 to 0.13 inches water.  High snow/water ratio could give us as much as 1.5 inches snow before ending about 7am.  But  accumulation could also be as low as a dusting, as Alberta clippers are notoriously difficult to predict.

The possible snow for Friday evening is no longer being forecast.
