While modelling shows less snow on Friday for the Northeast and Mid-Atlantic compared to a few days ago, one must consider the level of cold throughout the East and potential increase in ratios which could produce greater accumulations, especially nearer relatively warm water.

The mountains of West Virginia and Virginia look to take the prize according to the models at perhaps 3-6 inches while there is a large area of a coating to 2 inches extending from North Georgia to New England. Nearer the coast where there is more moisture thanks to frigid air and relatively warm waters, don’t be surprised to see 3-6 inches nearer the Atlantic as well as perhaps Chesapeake Bay.

In the latest run of the GFS (below), notice the rain-snow line extends all the way into North Georgia. Atlanta may either get a rain to snow or ice event out of this,

Here’s the latest GFS snow amounts by Saturday AM.

Below are forecast low temperatures ahead and after Friday’s system. You’ll not see cold to any great degree on your local tv weather forecast for Friday morning or Saturday night into Sunday but don’t understand either the cold of this air mass or the role the fresh snow can play.

You only have to see what’s diving into the Upper Midwest tonight to realise how cold the air may get after is passes over fresh snow cover Saturday night.

New York City may see single digits Friday morning (ahead of the system) or Sunday morning (after).

Friday AM

Note the southward extend of teens, possibly all the way through Atlanta and the below zero readings covering much of Pennsylvania and down the spine of the Appalachians. This suggests even the mountains of North Georgia getting down to near zero.

Sunday AM
