"Incredibly Harsh Arctic Airmass" Set To Plunge Half Of US Into Record Cold

"Incredibly Harsh Arctic Airmass" Set To Plunge Half Of US Into Record Cold

Earlier this week,

head meteorologist at , said several blasts of Arctic air would roll into the Mid-Atlantic and Northeast regions this week and early next week. 

The first round of cold air has arrived, and it's absolutely freezing in the Northeast. 

Vallee said the first round of cold air is an appetizer for what's to come early next week. He noted in his forecast below that, temperatures across the Midwest and Northeast could be on "average 20-30°F below normal." 

"A very cold air mass will penetrate the Midwest and Northeast U.S. into early next week. As a strong cold front moves through the Plains and Midwest Monday into Tuesday, temperatures will average 20-30°F below normal, leading to potential record cold high temperatures only in the 10s and 20s.

The cold will move into the eastern U.S., including the major cities in the Northeast by Wednesday and Thursday. High temperatures in New York City may fail to escape the 30s Wednesday. Temperatures into the 8-14 day continue to favor colder than normal temperatures in the eastern U.S," Vallee stated.

An incredibly harsh airmass is on the way next week with temperatures 20-30 degrees below normal for mid-November. Sunday-Thursday temperatures versus normal tell the story...

The second wave of Arctic air is expected to move through the northern Plains and upper Midwest Sunday, into the southern Plains and Ohio Valley Monday, then into the East Coast by Tuesday. 

Just a little 25 degree (!) departure next Tuesday, 11/12.

Hope you guys like cold!

High temperatures on Monday could be in the teens for much of the Midwest and areas around the Great Lakes. 

Vallee said daily high temperatures for some regions in the Midwest to the East Coast could set cold records on Monday through Wednesday.

By Tuesday, Arctic air will reach the Northeast, and could send temperatures plunging in the Deep South to the 30s. 

Arctic blast is courtesy of strong Canadian high pressure (1048 mb). By Monday, the brutal cold front reaches Texas with a good portion of the central Lower 48 experiencing freezing, record cold temperatures.

Vallee warned that a winter storm could develop across the central Plains early next week, which would likely paralyze major highways and disrupt trucking routes. He added that eastern and even southern regions of the country could see some form of wintery precipitation by next Wednesday.
