A winter weather advisory was issued for New York City ahead of Sunday's snow storm, which could drop anywhere from 3 to 5 inches across the five boroughs.
Further inland, a winter storm warning was also issued for a risk of heavier snow that could see parts of the tri-state accumulating 5 to 8 inches of snow. These alerts take effect midday Sunday.
In New Jersey, Gov. Phil Murphy declared a state of emergency on Saturday.

“As always, I urge all New Jerseyans to use caution, follow all safety protocols, and remain off the roads unless absolutely necessary," Murphy said in a statement.
Snow will move in before noon on Sunday, as temperatures drop below freezing. With colder air moving into the region and timing favoring the latter half of the day, temperatures for most of us are back below freezing, meaning this is largely an all-snow event. Expect snow to move in by early afternoon, continuing through the evening, tapering off just after midnight.

Along the Jersey Coast and the eastern end of Long Island, where temperatures start off a bit milder, initial rain and snow mixing is expected before snow fully takes over, resulting in relatively lower accumulations at the coasts.

Otherwise, we expect a general 3 to 5 inches in the New York City metro area. Further inland parts of northern New Jersey, upper Hudson Valley and into Connecticut, 5 to 8 inches are likely. And some higher elevation areas of northwest New Jersey and the Hudson Valley could get as much as a foot of snow.
Any shift in the storm track will change the location of the highest snow accumulations, but the general outlook remains the same: We are expecting plowable snow across the tri-state on Sunday. Be ready for shoveling and sledding on Monday, just be sure to dress for the cold.

The snow that falls on Sunday is not melting any time soon. Temperatures next week plummet into the teens and 20s for several days; morning lows fall to the single digits in the city.
We’ll experience the coldest blast of air of the season, with Tuesday, Wednesday and Thursday being the worst. Morning wind chills on those days could be sub-zero, making for downright dangerous conditions.
The end of January is climatologically the coldest time of year for Central Park. And this year is certainly delivering in that regard.
