A sharp southward plunge from the polar jet stream in Northern Canada is bringing cold to the U.S. Northeast, with the area expecting to see the coldest air of the winter season this weekend, and dropping the Midwest into subzero cold, according to The Weather Channel.
After averaging temperatures about 5 to 10 degrees above normal for a month, this weekend will bring temperatures that are 10 to 20 degrees lower than is normally expected this time of year, with Saturday, Feb. 13 seeing the coldest lows.
The mid-Atlantic region from southern New York to northern New Jersey and eastern Pennsylvania is expecting to see temperature lows of 0 to -10 degrees, and the Great Lakes area should mimic that. South of the mid-Atlantic and Ohio Vally (down to northern Tennessee and southern Indiana) should see temperatures in the 10 degrees and lower range, reported AccuWeather.
