That massive, nasty storm that's been pounding the North is supposed to swing southeast.
Arctic air floods Chicago to New York City
Arctic air bottled up over Alaska is being unleashed over the Midwest and will soon follow into the East. The cold air will spread southeastward in two waves this week. The second surge threatens to be the harshest and farthest reaching.
The first shot of arctic air is already plunging into the northern Plains behind a clipper system bringing blizzard conditions to many locations. The bitterly cold air will spread across the Great Lakes, Ohio Valley and the Deep South on Tuesday and the Northeast on Wednesday.
The second blast of cold will originate farther north in the arctic. It will follow close behind the first, spreading into the northern Plains on Wednesday. On Thursday and Friday, the coldest air of the season will spread across the Midwest and then the East.
Gusty, northwest winds will create dangerously cold temperatures with both arctic blasts. Residents of the central and northern Plains got a taste of those winds early Monday, when gusts climbed as high as hurricane force.
RealFeel temperatures by tonight will plummet to below minus 30° in the northern Plains, including in Fargo, International Falls and Duluth. This extreme cold poses a serious danger to people and pets. On top of the threat of hypothermia, frostbite could set in in only a matter of minutes.
How cold the air will feel on Monday may pale in comparison to Wednesday's RealFeel temperatures in the northern Plains, when the second surge of arctic air arrives.
By Thursday, Chicago will have a high within a few degrees of zero and a low temperature below zero.
That second blast of arctic air will hit the East late in the week and could hold the high temperature in the teens in New York City. Temperatures may dip below zero at night, a feat not achieved in the city since Jan. 19, 1994.
