Once again, a winter blast chilled much of the country Tuesday, with temperatures hitting record lows from Maryland to Michigan, forecasters said. The newest cold weather system set or tied record March lows in Baltimore, Scranton, Pa., Morgantown, W.Va., Zanesville, Ohio, and Flint, Mich. Thousands of motorists in Arkansas were stranded on interstates and slept in their vehicles overnight. In Louisiana, some Mardi Gras events were canceled while others saw low attendance. But the latest storm clouds have a silver lining: "This will be the last of the super-cold days, and over the next week much of the country will be back to average," a meteorologist at The Weather Channel said.
