Arctic Temperatures, 20 Degrees Lower Than Normal, to Grip U.S. This Week


The coldest and most far-reaching arctic blast so far this season will spread across the majority of the contiguous United States this week.

Frigid air from the depths of the Arctic will plunge into the United States as the jet stream (a fast-river of air along which storms travel) drops southward.

The coldest days of next week will yield highs and lows of generally 10-20 degrees Fahrenheit below normal from the Northwest and Rockies to the Gulf and East coasts.

Departures from normal highs will even approach 30 degrees in Billings, Montana, and Denver, Colorado.

The arctic blast will first chill the Northwest this weekend before spreading to the south and east as the week progresses.

The northern Rockies and northern Plains will face multiple days of highs in the single digits and teens. Subfreezing highs will then spread to the central Plains, Great Lakes and interior Northeast.

“Afternoon high temperatures in cities like Kansas City and St. Louis will only be in the 20s late in the week, while some places in the Dakotas may have a day or two where the temperature does not even get above zero,” AccuWeather Meteorologist Brian Thompson said.

“For many places in the East, temperatures on Friday will be lower than at any point during last year’s unusually warm December.”

Temperatures soared to a high of 69 F in Philadelphia on Dec. 12, 2015, for last year’s Army-Navy football game.

Fans and players will endure dramatically colder conditions for Saturday’s game in Baltimore. Temperatures will struggle to reach 40 F as biting winds blow.
