The snow mystery continues as models diverge:

  • Firstly, there will be some systems moving through the northeast today and tomorrow with some snow for NY state and New England (see 6th image). Long Island should stay dry today, but there is a chance of some sprinkles or flurries as the cold front comes through tomorrow mid to late afternoon. It will be a very cold weekend as it will be windy, especially Saturday.

  • The models have diverged with the storm for Monday night into Tuesday afternoon as the GFS, GFS-Parallel, and Canadian all now keep the snow south of Long Island. However, the Euro and UKMET still have snow for Long Island. In general though, it looks like a system mostly for PA and NJ, although I do think Long Island will get some snow. This will not be a big snowstorm though; I am generally thinking 2 to 4 inch potential for Long Island. Almost every Euro ensemble member has some snow for Long Island, with an ensemble mean of 4 inches. The ensemble mean for Boston is only 2 inches, as it should stay mostly south of there.

  • The models also diverge for late next week, but in general, it looks like there is slight potential for a Mid-Atlantic snowstorm sometime late next week or next weekend. According to the Euro ensembles, while still a low chance, the best chance for Long Island might be around next Sunday (1/31).

  • In general, it looks like slightly milder temperatures for the first week of February.
