The National Weather Service has issued Winter Storm Warnings and Winter Weather Advisories throughout the New York City Tri-State Area. Updated ice accumulation forecasts have indicated a much more significant level of ice accretion for locations to the north and west of the city, making for potentially dangerous roadway conditions Tuesday afternoon as well as setting up the possibility for isolated to potentially widespread power outages going into Tuesday night.
Plan on steady snow developing by mid-morning Tuesday, with the potential for snowfall rates exceeding 1 to 2 inches per hour in the first couple hours of the storm. While the exact timing of the transition from snow to wintry mix (sleet, freezing rain, and snow) depends heavily on specific location, most areas – excluding Long Island, where the transition could occur more rapidly and sooner than elsewhere – will see this changeover around the early to mid-afternoon.
Roadways will become dangerous by early afternoon due to periods of heavy precipitation and ice accretion. Please avoid unnecessary travel during the worst of the storm, with extreme caution on both treated and untreated roadways due to ice, snow, and reduced visibility. Most locations should see conditions rapidly improve Wednesday as temperatures are expected to go above freezing.
A significant snowstorm expected to bring blizzard conditions and up to a foot of snow to portions of Virginia and the Southeast may bring up to several inches across the Mid Atlantic and the Northeast, prompting winter storm warnings and winter weather advisories for portions of Long Island and eastern Connecticut. The National Weather Service also forecasts light snow accumulation for much of the Metro Area, with areas of Long Island receiving as much as 6 to 8 inches of snow by tomorrow night.
Weather 360 forecasts up to 4 inches of snow for much of southwestern Connecticut, and a half foot or more of snow for much of Long Island. As the snow will start around midday, travel in the afternoon may become slick and at times there may be periods of low visibility.

A low pressure system currently located over the Southeast is on its way northeastward, and is expected to impact large swaths of the East Coast tonight into early tomorrow morning, prompting winter weather advisories for locations across southern Connecticut and New York, as well as in parts of New Jersey. Expect the snow to create slick conditions for the morning commute, as it will quickly stick to the ground and pavement.
Weather 360 is forecasting a maximum snow accumulation of about 3 inches in locations close to the coast, with a trace to an inch of snow further inland.
