Around the middle of December, an even colder blast of air will follow this week’s frigid conditions over the central and eastern U.S. This next major push of arctic air will follow a series of snowstorms over part of the Northern states. Temperatures from the northern and central Plains to much of the Midwest are likely to be 5 to 20 degrees Fahrenheit lower, on average, when compared to levels this week. High temperatures from the plains of Montana to portions of North Dakota and northern Minnesota may be at or slightly below zero for one or more days during the first part of next week. The lower temperatures will follow this week’s highs in the single digits and teens for the same region. In Chicago, highs in the 20s and lower 30s this week will be replaced by highs in the teens by the middle of next week. A substantial temperature dip is likely across the interior South and Appalachians during the latter part of next week.
Bitterly cold air to come in waves across US into next week
