Research Affiliate Judah Cohen speaks to USA Today’s Doyle Rice, Dinah Voyles Pulver and Janet Loehrke about the intensity of the polar vortex this year, and his predictions on what sort of weather the upcoming winter season will bring across the country. “The polar vortex is no longer record strong (signaling a milder winter) and it is actually a bit weaker than normal as it is undergoing a polar vortex stretch,” says Cohen. "It looks like that over the next two weeks the PV will be near normal or slightly weaker than normal.”
