(CNN) — The ice man cometh. And does so early this year, after a former Pacific typhoon flew up toward the arctic and rammed the jet stream.

The stream has whipped south, dragging down frigid air from Canada over the northern Plains and Mountain states and the Upper Midwest, according to the National Weather Service.

It is already plunging temperatures below freezing there and will hammer them into the teens and single digits in many places by mid-week, even lower in others.

Great Falls, Montana, will shiver at -9 degrees on Tuesday night.

It’s the “coldest weather of the season,” the weather service said.

Let it snow

The snap is forecast to lay down the first broad layer of wintry snow, flurries, sleet or ice — long before winter starts — from Montana, down to Nebraska and over to Wisconsin.

It will accumulate in inches in the northern Rockies, northern Plains and Great Lakes.

People further south will also shiver. “Much of the nation east of the Rockies is expected to see a major pattern change by the beginning of the work week,” the weather service said.

Lows will drop to freezing in Kansas City late Monday then into the 20s a night later. The snap will chill Tennessee and Oklahoma but then stop short, leaving the Deep South and South West in a fall-like warm zone.

Residents in the northern United States can thank a whopping tropical cyclone in the Pacific Ocean for the wintry blast.

The remnants of Super Typhoon Nuri rolled up north over Alaska’s Aleutian Islands on Friday kicking off the ripple of arctic air in the other direction.

Earlier in the week, Nuri was tied for strongest typhoon of the season based on wind speed. Its remnants plowed into cold air adding violent energy as it went north, similar to the way Superstorm Sandy did in the Atlantic two years ago.

That gained it the weather moniker “bomb cyclone.”
