Cold Weather is Here, But When Will Long Island Get Snow?
Today is the first day of an extended period of very cold weather on Long Island, where temperatures will probably not get above freezing, even during the afternoon. Some day, especially between Thursday and next Tuesday will only be in the low 20's during the day and between 8 and 13 degrees at night.
The models have been signalling the potential for a snowstorm sometime this weekend for a while now, but there is still not a convergence in the models yet. The GFS is showing the first storm for this Friday into Saturday will stay offshore of Long Island, but it's showing a second storm bringing 6 to 8 inches of snow from around midnight on New Year's Eve until around midnight on New Year's Day.
The Euro has been fairly consistent in showing one storm for Saturday into Sunday morning. The latest run is showing 10 to 20 inches for Suffolk and 6 to 10 inches for Nassau.
So, at this point, we don't know exactly when it will snow, but confidence is increasing in an accumulating snow for Long Island sometime this coming New Year's weekend.
