This morning’s models still show the upper air clipper low moving through our area Saturday morning.   The GFS has the system weakening as it approaches Philadelphia, with a QPF that is now about 0.06 inches water.   The NAM doesn’t weaken the system and maintains a QPF of about 0.11 inches water.

The light snow starts about daybreak and ends about noon.  Depending upon your model of choice and the expected high snow-water ratio of 15:1 or 20:1, we could get about 1-2 inches, but a mere coating is also possible.

I’ll update with tonight’s models.   The early NAM data becomes available as early as 9:15 PM

Fri 5 PM: This afternoon’s models have the very light snow starting a bit later and ending early afternoon.  The trend has been towards less QPF.   The experimental NBM (National Blend of Models) has a QPF of 0.06 for our area, or about about a coating to 1 inch of snow.
