New update from NWS for Long Island snow:
With their late afternoon update, they continue the Winter Storm Warnings with snowfall amounts of 8 to 14 inches for all of Nassau and western to central Suffolk with 3 to 9 inches for southeastern Suffolk and 5 to 9 inches for northeastern Suffolk.
I will post the new map when they update it. This is the latest map for now. The 2nd image shows the radar at 3:55 PM, and you can see the heavy snow off to the southwest.
