A brutal Arctic air mass is about to take over the United States

When is “global cooling” a crisis? When is “global warming” coming back? When will people see “climate change” for what it is, a cop-out?

Temperatures as much as 30 to 50 degrees below normal are entering the Northern Plains as we close out the workweek. Through the weekend, brutal conditions you might expect in a frigid January overtake the central portion of the country, from the Mexican to the Canadian borders.

Heading into the first full week of March, Arctic air takes up residence in the East as well. When it’s all done, most of the contiguous United States will endure a punishing blow of frigid air from this Arctic blast. Records for cold are likely to be most numerous in the north-central United States but will extend from coast to coast.

The setup

By March, many folks are searching for spring. For the time being, it will be hard to find. Some of the coldest air in the Northern Hemisphere is headed into the Lower 48.

“It’s a straight shot from the Arctic!” tweeted Steve Glazier of Weather Nation.

An unusually strong high-pressure area currently near northern Alaska will drift through the Arctic in the days ahead, forcing subzero air that is usually centered in the polar region to move southward.

The coverage and intensity of the cold over the Lower 48 may peak on Monday. The European modeling system is forecasting average temperatures for the day of 20 to 40 degrees below normal over a huge chunk of the Lower 48. The core of the cold will span from the Pacific Northwest to the Great Lakes in the north, and from Texas to the Ohio Valley in the nation’s south and midsection.

Beyond Monday, the coldest temperatures ease slightly as they drift eastward.

Central U.S. faces the heart of this Arctic outbreak

The worst of this cold shot is predicted for the north-central portion of the country, where widespread dangerous conditions are expected.

It was way too cold in Montana even before this cold shot arrived — some spots finished close to 30 degrees below normal for the full month of February. This Arctic blast is still ready to take it to the next level of extreme.

Widespread temperatures 40 to 50 degrees below normal are expected by Saturday night into early Sunday across Montana. That equates to highs below zero, and lows more than 20 degrees below zero.

The NWS in Glasgow, Montana, says that “wind chills may dip into the minus-50s by Sunday morning.” At temperatures like these, frostbite is a major concern.

A similar forecast story is being told to the east across the Dakotas and into the Upper Midwest. In Duluth, Minn., where they’re working on two months of consecutive below freezing conditions, wind chills are expected to fall to the minus-30s. Actual temperatures are only in the minus-10 to zero-degree range for highs on Sunday, after lows in the minus-10 to minus-20 zone.

Subzero temperatures are anticipated as far south as parts of Colorado, Kansas, Iowa, Illinois and, perhaps in isolated fashion, even into Oklahoma, Texas and Missouri on Sunday morning. Wind chills may fall to their lowest level of the winter in Oklahoma, dipping below zero.

Highs on Monday may only be around 20 in Oklahoma City, the 30s in Dallas, and the 40s near the Gulf Coast.

Wait…again? I thought we just dealt with the polar vortex! It’s March - need to start getting ready for spring.

“Last Gasp of Winter” not exactly anything we haven’t seen before.

Of course now it’s due to “Global Warming”.

“Global warming” is also responsible for the ice rings on Saturn melting, 98% of climate scientists said.
