Research Scientist Judah Cohen speaks with USA Today reporter Doyle Rice about how changes in the polar vortex will impact March weather across the United States. “I would expect a milder period in the eastern US until close to the spring equinox," says Cohen. "Then I think eventually colder weather arrives to the eastern U.S. related to the polar vortex split in late March or early April that could hang around for a while."
