Update (3:45 p.m.): The National Weather Service has reissued a Winter Weather Advisory for all of Long Island, including Nassau and Suffolk Counties, as the storm affecting the area today is expected to redevelop and draw in colder air as the sun goes down.
The new advisory matches the original issued on Friday, expiring on Sunday at 6 a.m.
The new forecast calls for a blast of heavy snowfall as the sun goes down and temperatures along with it, bringing anywhere from 2 to 4 inches of snow across the Island.
The National Weather Service is also forecasting the possibility of hazerdous driving conditions as slick roadways ice over and snowfall picks up. Winds will be between 10 and 20 mph with gusts to 35 mph, causing blowing snow and visibilities to drop to a half mile.
Original Story: A Winter Weather Advisory issued for Nassau County and western Suffolk County yesterday by the National Weather Service has been cancelled.
The initial advisory forecasted a snowfall total of 2 to 5 inches across western portions of Suffolk County, with much less expected due east as the rain-snow line would infringe on the area.
The storm's track today has shifted slightly to the west, bringing more rain than snow to Long Island and above-freezing temperatures. Heavier precipitation should also be with this more eastward side of the storm, so slick roadways will still be a problem as temperatures fall throughout the afternoon.
Snowfall will begin on Long Island late this afternoon into the early evening as the storm draws in colder air from Canada. The snow should stop falling by late this evening.
Final storm totals for areas are expected to be anywhere from 1 to 2 inches, with localized areas at 3 or 4 inches.
Stay tuned to Patch as we continue to monitor the storm!
