A bitter blast of arctic air will result in dangerously cold conditions this week across the Northern Rockies, central and northern Plains and the Upper Midwest, with temperatures dropping well below zero and wind chills reaching -50 to -60 degrees in some spots by the tip of the week, in line with the FOX Forecast Center.
Subfreezing temperatures will eventually reach as far south because the Gulf Coast as thousands and thousands across the region will feel their coldest winter-time temperatures in several years. Dangerously cold temperatures will then spread into the Great Lakes and Northeast by the weekend, freezing areas within the wake of what’s expected to be a crippling winter storm with blizzard conditions and the potential for widespread power outages.
“High pressure parked over the Northwest Territories of Canada at once scoops up that cold air form the poles within the Arctic after which pushes all of it the way in which down and into the Northern Rockies, Dakotas and Upper Midwest,” said FOX Weather Meteorologist Steve Bender. “A developing low pressure center over the Great Lakes will then tap into that arctic air and speed up it down into the Southern Plains.”
Northern Plains may remain below zero for days
The arctic air began its week-long journey by surging south out of Canada over the weekend, and already low temperatures Monday morning were no less than -20 or colder across northern Montana – Glasgow had a forecasted low temperature of -24 while -16 was expected in Great Falls. With the winds, wind chills were already around -35 to -40 degrees.
It’s an indication of the depth of the cold air about to spread across much of the remaining of America’s heartland. Wind Chill Warnings and Watches already stretch across much of the Upper Midwest:
Forecast highs for Monday across the Northern Plains were barely in single digits across Montana, North Dakota and South Dakota – Bismarck fell below zero Saturday night and remains to be not expected to succeed in zero on Monday – or any day this week.
Bitterly cold temperatures will move south and east over the following few days. On Tuesday, some morning low temperature readings could approach -30 degrees across portions of Montana and North Dakota, with Bismarck hitting a low of -15, Pierre, South Dakota dropping to -10 – and even Minneapolis dropping below zero.
Denver will “only” drop into the mid-20s, however it’ll feel warm in comparison with what’s coming later within the week.
Wednesday morning will see temperatures drop below freezing across much of the Midwest, even stretching as far south as Texas. Within the Northern Plains, freezing temperatures shall be so far as 50 degrees away with temperatures approaching -20 or colder. With temperatures that low, frostbite could emerge in as little as 10 minutes.
It’s not only the cold that comes with the arctic front, but a period of snow and gusty wind will spread across the Northern Plains Wednesday afternoon, reaching as far south as Oklahoma and as far east as Michigan by early Thursday. Winds will gust from 30-55 mph, making travel hazardous from Kansas to Wisconsin.
Wind chills drop as little as -60 on Thursday
By Thursday morning, much of the heartland is throughout the full icy grips of the arctic blast while heavy snows will begin to bury the Great Lakes region.
Morning temperatures shall be as cold as -30 in Casper, Wyoming, with -22 likely in Billings, Montana. But sub-zero temperatures will spread far to the south, with a morning low of -12 forecast for Denver, -10 in Omaha, Nebraska, and even -3 in Salina, Kansas.
Even the inland Pacific Northwest will feel the sting of the arctic blast, with lows in Boise dropping to around 5 degrees and morning temperatures around -10 degrees in Spokane, Washington.
But as cold as those temperatures seem, the wind chills will border on the absurd for much of the Northern Plains and Upper Midwest.
Widespread wind chill readings of -40 to even -60 degrees are likely across the Dakotas, Montana and Wyoming, with -30 readings in parts of Iowa, Nebraska, Kansas and even Denver. Nearly 3 million individuals are forecast to experience wind chill readings of -40 or colder on Thursday, in line with FOX Forecast Center, with nearly 90 million experiencing wind chills below zero.
South goes into the Deep Freeze
After spending days freezing the Midwest, the bitter blast of cold air will surge south and east Thursday into Friday. That may send temperatures tumbling from the southern Plains to the Southeast.
Morning low temperatures Friday morning are expected in the kids and single digits as far south as Oklahoma, Arkansas and Tennessee, in line with the FOX Forecast Center, while temperatures will remain in the kids from central Texas to Georgia. Dallas-Fort Value Airport may dip below 10 degrees Friday.
“Areas like Oklahoma, Arkansas, northern Texas and northern Louisiana, and the Mississippi Delta, you’ve gotten to prepared for the cold in addition to potential power outages because the wind gusts shall be quite strong together with the potential for a freeze,” Bender said.

The nippiness will likely be a few of the coldest readings in no less than five years for a lot of areas east of the Mississippi River, and Wind Chill Advisories could also be needed all of the strategy to the Gulf Coast.
Several locations across the South may not get out of the kids or 20s on Friday, setting records for lowest maximum temperatures.
