Update on the next Arctic blast and uncertainty for the late-week storm as rain to snow is possible:

- This is the obligatory reminder that Daylight Savings Time begins at 2 AM tomorrow as time skips to 3 AM.

- The details for Long Island are in the forecast below, but it will become very windy again tomorrow afternoon with snow squalls in New England as the Arctic blast arrives with gusts up to 45 mph as another Wind Advisory may be issued. Wind chill temperatures as low as 5 degrees on Long Island by early Monday morning.

- The system for Tuesday evening looks very weak, but it could produce some snow showers on Long Island.

- There is still uncertainty regarding the late-week storm as shown by the storm locations from the Euro ensembles at 2 PM Friday in the 3rd image. It could be a rain changing to snow scenario for parts of the northeast, and the Euro and Canadian models even have it changing to snow on Long Island on Friday.
