Continued snow updates with heavy snow this evening for Long Island and possible thunder:

See previous post for the complete update. It's possible that the snow could start as early as 3:00 this afternoon in Nassau, but there is dry air to overcome first. Snowfall rates this evening though will be 1 to 2 inches per hour for several hours, especially from around 8 PM to midnight before any sleet starts to mix in along the south shore. The HRRR model is showing 7 inches of snow already for northern Nassau by midnight with 4 to 6 inches by then for most of the rest of Long Island. There may also be thundersnow or thundersleet. It's going to be a wild scene, especially from around 10 PM to 1 AM as the winds also increase to over 40 mph with gusts over 50 mph along the shore in southern and eastern Suffolk, creating blizzard conditions.
