Low temperatures are expected across the continental US as arctic blasts are expected to arrive in the coming weeks after being stuck in Canada.
Due to current wind conditions and Sudden Stratospheric Warmings, the polar vortex is slowly coming down and will arrive during Superbowl weekend.
Chicago, Nashville, the Midwest, and the South with temperatures abruptly falling 25 degrees or more would be the first places to get hit as early as Friday.
The National Weather Service (NWS) predicted that temperatures could drop by as much as 20 to 30 degrees below normal in the Upper Midwest while Minneapolis and Chicago could get below zero temperatures over the weekend.
“Bitterly cold to extreme cold air mass arriving over the weekend and continuing into next week, with low temps in some spots 10 below or colder and wind chills of -20F to -30F or even colder possible on Sunday night into Monday,” said NWS Chicago.
The NWS said that almost all of the US except parts of the desert Southwest, South Texas, and central and southern parts of the Florida Peninsula will experience chillier temperatures.
Forecast models have shown that the cold air will continue southward unit early next week but the NWS is unsure how far it will reach.
