The National Weather Service’s forecast discussion has the story:
Snow should change to rain at the coast around 8 am and by 10 am across the interior. Along the coast, there could be an hour or two of freezing rain due to the cold ground temperatures, while the interior could see up to a tenth of an inch of ice, possibly as much as quarter inch, before changeover to all light rain/drizzle late morning/early afternoon. Snow accumulations will range from 1-2 inches at the coast, to as much as 4 to 6 inches across northern portions of the Lower Hudson Valley and SW interior CT. Thus, winter weather advisories remain in place. Mid levels dry out tomorrow afternoon with light rain and drizzle through Saturday night. . . .Looking for about a 1/2" of [rain on Sunday] QPF. Temps Sunday running nearly +15 F despite the rain, but fall short of records (perhaps KISP - but that has a short POR). PCPN ends before temps support any frozen. Windy on Sunday as well with gusts up to 30 mph - especially in the afternoon just after the FROPA.
