After a very cold upcoming weekend in the northeast, all of the models (Euro, GFS, ICON, Canadian, and UKMET) now show some snow for Long Island, but there will be a sharp cutoff to the northeast, so there may not be much snow in southern New England once you go beyond SW CT. The Euro and its ensembles really showed a big change with the sharp cutoff to the northeast (see images below), and the Euro also had a later start of the snow on Long Island. Overall though, there is the potential for 2 to 4 inches in Nassau and 1 to 3 inches in Suffolk from late Monday night into Tuesday afternoon or evening, but let's see how this evolves and what the higher resolution models like the NAM, RGEM, and HRRR show once we are within range.
After that, the next storm should bring some snow to parts of North Carolina and possibly southern Virginia and northern South Carolina as it heads east and intensifies off the coast.
It doesn't really look good for any potential snowstorms on the horizon going forward into early February.
