A Winter Weather Advisory was issued for NYC, Long Island, parts of New Jersey and Westchester County for tomorrow as snow and frigid cold temperatures will create hazardous travel conditions, especially during the evening commute. Some local school districts have already announced closings and early dismissals in anticipation.


Here's when the New York City area can expect snow, when conditions will be the worst, and how many inches we'll see by Saturday.

Thursday night: Skies will remain cloudy and temperatures will dip down to a chilly 28 degrees in the city. 

Friday morning: A light, dry snow develops southwest to northeast between 6 a.m. and 10 a.m., initially falling at a rate of 0.25 inches per hour. New Jersey and the western Lower Hudson Valley will see the snow first, around 7 a.m., while flurries will start to pile up in NYC and Long Island around 10 a.m. Temperatures will remain in the low- to mid- 20s, perfect conditions for snow to stick and accumulate. 

Friday afternoon: Between noon and 7 p.m., the snowfall begins to accelerate, at about 0.5 inches per hour, according to the National Weather Service. Temperatures may reach 30 at its highest. The snowfall will create low visibility for the evening commute.

Temperatures will sink into the bitterly cold low teens, with wind chills in the lower single digits.

According to the long-range temperature outlook from NOAA's Climate Prediction Center, next week will likely feature above-average temperatures for late January across much of the U.S.

"We are going to have our own natural heater come next week, thankfully. Across the country, the entire Lower 48 expects to be above average in spots that were well below," said FOX Weather Meteorologist Jane Minar.
