The latest NAM data has become available. Following a rainy night tonight, storm intensification as previously predicted occurs as a secondary low pressure system winds up south of Long Island and moves southeastward.

Temperatures at critical levels of the atmosphere will become cold enough for snow as early as 7-10 AM, so the rain will transition to wet snow at that time.  QPF values as high as 0.70 inches water would ordinarily result in 7+ inches of snow, but for all the reasons enumerated in previous posts,  total accumulations will be much less and difficult to estimate.  Preferential grassy surface accumulations will still hold, with even less on paved and asphalt surfaces. Best guess is still 2-4 inches on grassy surfaces.

Strong winds develop during the afternoon on Friday, with highest winds during the afternoon. The HRRR model has  predicted wind gusts to be as high as 60mph! 

Snow ends about 7 pm.
