Accumulating snow possible in the mountains of north-central and northeastern Pennsylvania and highly likely in western, central and northern New York and New England during Saturday night and Sunday.
AccuWeather Global Weather Center – January 3, 2020 – A storm system will soak the northeastern United States and bring another dose of winter weather that will bring accumulating snow to parts of the region.
The first half and last half of this dynamic storm will be like night and day in terms of weather and precipitation type for many locations.
Aside from a brief period of freezing rain in portions of northeastern New York state and central New England at the storm's onset, precipitation will begin as rainfall with mild conditions entrenched across much of the Northeast.
The second half of the storm will be the colder and wintry part and responsible for some snow away from the coastal mid-Atlantic and southeastern New England.
It's possible that precipitation may hold off until the storm is ready to bring all snow to northern New England later this weekend, according to AccuWeather meteorologists. There is likely to be little if any accumulating snowfall from Washington, D.C., to New York City and Boston, but the northern part of this swath is likely to at least have some snow mixing in at the end of the storm during Saturday night and Sunday.
Because the storm is now expected to remain weak and move at a rapid pace, there is less of a chance that accumulating snow occurs on non-paved surfaces in the northern suburbs of New York City. However, that potential still exists to the north and west of Boston.
