Timeline:

Here’s what we can expect this weekend and next week.

Sunday afternoon: A Winter Storm Warning takes effect in the Lower Hudson Valley, interior northern New Jersey and most of interior Connecticut. A Winter Weather Advisory takes effort for the city, nearby New Jersey suburbs, Long Island and coastal Connecticut.

• When does snow-rain mix turn to snow? By 4 p.m.
• How fast will snow fall? Peak snowfall rates will be around a half-inch to 1 inch per hour.

Sunday night: Temperatures in the city are expected to fall into the teens to 20s. Travel conditions are expected to be hazardous due to slippery travel. Snow is expected to continue throughout the night.

Early Monday morning: The Winter Storm Warning and Winter Weather Advisory end at 4 a.m. Wind chills could be as low as 5 degrees.

• When does the snowfall stop? Snow will start to dissipate around 1 a.m.

Monday: Expect sunny skies, with high temperatures in the 20s before dipping into the teens. Expect wind chills as low as -5 to -15 degrees into early Tuesday morning. Due to the Martin Luther King Jr. federal holiday, schools, banks, and other services that would normally be in session on Monday have the day off, which will help keep roads clear for snow removal crews.

Tuesday night wind chills (NWS)

Tuesday and Wednesday: Highs will linger in the teens, maybe reaching 20 degrees. Expect wind chills between 0 and -10° Tuesday night into early Wednesday morning.

New York City and the nearby suburbs can expect between 3 and 5 inches of snow, according to the National Weather Service. Up to 6 inches is possible.

The Lower Hudson Valley, interior New Jersey and most of Connecticut will see totals ranging between 5 and 8 inches. Eastern Long Island should get mostly a rain-snow mix.

If heavier snow banding develops over the region, New York City could see up to 8 inches of snow, with 10 to 12 inches possible for the Lower Hudson Valley.

There is a 90% chance NYC sees at least 3 inches of snow.

Polar vortex and subzero wind chills

This weekend and into next week, a lobe of the polar vortex will descend into the U.S. and bring with it brutally cold temperatures.

The FOX Forecast Center said temperatures will plummet as much as 45 degrees below average in spots, leading to below-zero temperatures across at least 20 states, from the Plains to the Great Lakes and interior Northeast.

Preparations for the cold weather are already underway in New York City. According to New York City Emergency Management, a Cold Weather Alert has been issued and the New York City Department of Public Health declared a Cold Blue.

“Outreach teams will canvass all five boroughs to connect our most vulnerable New Yorkers to shelters,” NYCEM said on X. “No one who is homeless and seeking shelter in New York City during a Code Blue will be denied.”
