LI forecast and maps for the big storm early next week with a chance for a 2nd storm late next week:
Regarding Thanksgiving tomorrow, the NAM is showing the rain ending by 2 PM in Nassau and 4 PM around Montauk, but the timing could still be a little later than that.
All indications continue to point to a strong storm moving well inland early next week with heavy snow well to the west, but a period of heavy rain and strong wind gusts still looks likely for Long Island and New England with the potential for 40 mph to 55 mph wind gusts Monday night into Tuesday morning with at least 1 to 2 inches of rain with higher amounts possible.
The Euro and Canadian models are showing a 2nd storm for late next week coming up from the south, and this one should be farther east with the potential to bring snow for parts of New England.
