Models show less snow for Long Island and there is intrigue with the big Thursday storm:

Overall, the models are showing less snow on the northeast fringe of the storm for late Monday night into Tuesday night. There are still differences in the models though, and we are now within range of the 12km NAM, which has very little snow for Long Island, and the Euro ensemble mean is only around 2 inches. The GFS also has even less snow for Long Island.


However, the Canadian and GFS (5th and 6th images) are farther north initially with the potential big storm on Thursday; they both have Long Island getting some snow, although they do both generally have the storm move east offshore, but starting from a more northerly position. The Euro (7th image) is much weaker with the storm and has no snow for Long Island; however, a handful of Euro ensemble members do show an accumulating snow on Long Island.
