Here's the Euro from Friday morning to Saturday early afternoon and HRRR images for 6 AM tomorrow:

It's showing some brief snow/sleet Friday late morning and then rain for Long Island. There could be some pretty big snow totals in the central to northern areas of NY/New England, especially at elevation, but let's see how this shifts in the next couple of days.

The 2nd and 3rd images show the future radar and snowfall amounts at 6 AM tomorrow.

I will post the updated National Weather Service snow map when it comes out later this afternoon.
