Another arctic front Thursday

Minnesota is riding the edge of bitterly cold arctic air across central and eastern Canada. We enjoy briefly milder air overnight into early Thursday. Then the next arctic front drives subzero air south once again Thursday night into Friday morning. Temperatures then quickly moderate again into the 20s above zero as we head into the weekend.
