Snow follwed by dangerously cold temperatures this weekend

Another weekend will bring snow and bitter cold to parts of the country—this time across the Ohio River Valley, Mid-Atlantic and Northeast. Wind chills could plunge to 35 degrees below zero.

Snow chances

A cold front will bring snow to New York and New England from tonight through tomorrow. Totals will generally be light—around 1 to 3 inches—but a unique phenomenon known as ocean-effect snow could enhance accumulations in eastern Massachusetts and southern Maine (including York County).

A heavy band may develop there, with localized totals exceeding 6 inches. If this occurs, the most likely timing is early Saturday afternoon.

Here’s one model’s timing on the snow.

Cold Weather Alerts

Arctic air will move in behind the snow starting Saturday night. Area-wide temperatures will dip near zero, and gusty winds could drive wind chills down to 30 below.

Cold Weather Advisories are in place for the Lakes and Mountains region of Maine, Ohio and eastern Michigan, with Extreme Cold Warnings set to go into effect for New York State and western Massachusetts.

Cold weather alerts will remain in effect through Sunday afternoon.

A Cold Weather Advisory is issued when dangerously cold wind chills can cause frostbite on exposed skin in as little as 15 minutes. An Extreme Cold Warning is issued when frostbite and hypothermia are likely if skin is left unprotected.

Frigid wind chills

The cold will settle in Saturday night and remain locked in the Northeast and New England through Sunday. A gradual warmup will begin on Monday. 

Several of these areas were hit with heavy snow two weeks ago, and much of it remains. Additional snow this weekend will only build bigger piles.
