Cross-country cold: Blast of arctic air puts smackdown on temps

A southward progressing cold front will bring a reinforcing shot of arctic air into nearly the entirety of the U.S. this weekend. Highs behind the front will dip even colder than earlier this week, nearly 15-25 degrees below average. This blast of arctic air could prevent high temperatures from going above freezing as far south as Texas.
