The upcoming systems with northeast snow potential and the Long Island forecast:
The details for Long Island are in the forecast below, but the snow map for the northeast through 7 PM Thursday is shown in the 1st image with the accumulations for today being mostly north and northwest of Long Island and the accumulations for Thursday being mostly south and southwest of Long Island.
The storm for the weekend looks like it will bring some snow to the northeast, but it doesn't look like a major storm. The timing looks a little later, so it would be mostly later Saturday night into Sunday afternoon/evening, and it could change to some sleet or even rain right along the coast (see maps from the Euro in the 3rd and 4th images).
It then looks like a more significant storm for Tuesday night into Wednesday next week. As of now, it looks like snow changing to rain for Long Island and parts of southern New England with significant accumulations possible inland.
Of course, I will have more updates today with the latest information.
