Forecasters Decrease Mid-Week Snowfall Estimate for Long Island

Snow remains likely late Wednesday into Thursday, but the National Weather Service has decreased its snowfall total prediction for the island.

The latest forecast calls for less than an inch of snow to fall across most of the region. The South Shore “may see around an inch,” the NWS says. Earlier estimates had predicted up to 3 inches of the white stuff.

Low pressure moving south of the area will result in increasing chances of snow Wednesday afternoon, with snow becoming likely Wednesday night before tapering off Thursday as the low exits well offshore, the NWS says.

A ”slight northward shift” by the low pressure system could result in a “worst case” 2 inches of snow across the island, the NWS says.
