Severe weather shifted west on Monday, with a polar vortex set to ensnare the Rockies and northern Plains after winter storms battered the eastern U.S. during the weekend, claiming at least 10 lives. Nine people, including a child and a mother, perished in Kentucky as a result of flooding due to heavy rain.
The National Weather Service posted a warning for ‘life-threatening cold’ through Tuesday, with temperatures in northeastern Montana dropping as low as 45 below zero (-42.7°C), with wind chills of 60 below (-51°C). Meteorologists forecast this would be the 10th and lowest polar vortex event of the season, caused by Arctic weather patterns forcing cold air into the U.S. and Europe.
