Just in! 18 to 24 inches for me now in northwest Nassau!
The following is from NWS NY: "New snow forecast: 18"- 24" for NYC, NE NJ, Lower Hudson Valley, much of Nassau, & portions of SW CT. Lesser amounts as you head E due to warm air aloft & at the surface, changing snow to wintry mix of rain, snow, & sleet. A changeover to all rain is likely for Twin Forks of LI."
Wind gusts will also be up to 60 mph in eastern Suffolk and 50 mph for the rest of Long Island. It looks like they decided against Blizzard Warnings, surprisingly. They are saying 12 to 20 inches for western Suffolk and Nassau and 5 to 13 inches for eastern Suffolk.
