Update on the storm early next week as uncertainty remains:
Firstly, light snow is moving through Long Island now with a coating by me already in northern Nassau, but it's moving through quickly. Also, precipitation will be hanging around eastern MA for a while, including even a little trough extending to the big offshore storm later on Friday, which could bring some snow there. As for the Arctic blast, it's going to be intense, especially from late tomorrow night into Saturday, although it will still be very cold early Sunday morning, but the wind will have died down. Wind chill temperatures will drop below zero on Long Island Friday night into early Saturday morning.
Ok, now for the storm, and well, it's complicated. It looks like a long duration event from late Sunday night into Tuesday night or Wednesday morning in the northeast. For Long Island, as of now, and this will change, it looks like snow, possibly mixing with and changing to rain for a while on Monday, and then possibly going back to snow on Tuesday. Also, if you look at the images below, you will see the uncertainty based on the spread in the location and track of the storm as shown by the Euro ensemble members. That is why some ensemble members show less than an inch of snow for Long Island, and some show around 9 to 12 inches. It's just too soon to be confident in any given solution, which is to be expected at this range.
Later next week into next weekend it will turn milder with some rain for most of the northeast, but then there should be more snow chances towards mid-February.
