Southern parts of Westchester, Rockland and Fairfield should see 1 to 2 inches of snow and sleet accumulation until the changeover to rain overnight into Friday. North of I-287 and the Merritt Parkway, look for 2 to 4 inches of accumulation, with 4 to 6 inches now expected north of I-84. In upstate New York farther north and west, more than a half foot is possible. (See the first image above.)
A Winter Weather Advisory is in effect for Westchester, Putnam, Rockland and Orange counties in the Hudson Valley and Fairfield County in Connecticut from 2 p.m. until 11 p.m. Thursday. A Winter Storm Watch is in effect for Dutchess County from 4 p.m. Thursday until 1 p.m. Friday.
The most treacherous conditions are expected late Thursday afternoon into the evening with slippery travel and reduced visibility as snow and sleet overspread the area starting at around 4 p.m. Thursday.
The wintry mix will continue for the entire region through around 11 p.m. Thursday before changing over to rain. Areas farther north will see freezing rain and some sleet and snow overnight through early morning, meaning school delays and even closures are possible farther north.
The entire region will see rainfall late Friday morning into the early afternoon as the high temperature climbs into the mid-40s.
Saturday will be mostly sunny with a high in the mid-40s.
