Confidence increasing in the heavy snow being for inland areas with snow to rain for Long Island:

- Firstly, we have the huge offshore storm on Friday, which will clip eastern MA and DownEast Maine and be a huge blizzard for Nova Scotia. There is even a slight chance of showers from it for eastern Long Island Friday morning.

- The big story for Friday night into Sunday morning will be the frigid temperatures with wind chill temperatures below zero on Long Island late Friday night through Saturday morning (the 2nd image is for 7 AM Saturday).

- The models continue to show the inland track with the strong storm Sunday night into Monday, and the ensembles have shifted west as well. Of course, it's not set in stone yet and there will be more shifts. With the current scenario, the early thinking is that it would be snow starting on Long Island Sunday evening/night with possibly an inch or so before changing to heavy rain with wind gusts over 40 mph.

- I will continue to update today into tonight with the latest info.
