Temperatures Plummet Across Midwest

CHICAGO —  Millions across the Midwest are feeling record cold this morning.  A polar blast of freezing air from Canada is plunging into the U.S. today, potentially breaking dozens of daily record low temperatures from the Plains to the Northeast.  Cities like Pittsburgh and Des Moines could break record lows this morning, and some areas could see temperatures below zero. Cold temperatures can lead to the use of fireplaces or space heaters, which can lead to house fires. Homes with plumbing on exterior walls may need to leave water running slowly to keep pipes from bursting, and cabinet doors should be left open to help prevent frozen utilities. The freezing weather is expected to continue into tomorrow.
