Latest NAM model data suggests  at least 4-7 inches of  snow, starting about noon and continuing into the evening  before a changeover to sleet and freezing rain later Saturday night. Higher amounts possible north and west.  Freezing rain may be extensive.

The trend is for more precipitation and prolonged colder temperatures, even in Philadelphia.  The latest NAM also suggests that the anticipated warmup late Saturday night and Sunday may not get as warm as previously thought.

While there’s been less advance coverage and hype about this storm, tomorrow’s weather  has the potential to be one of the more significant snow and ice ‘events’ of this winter.
