Tornadoes tore across the nation's midsection for a second night Saturday, 24 hours after a storm leveled Greensburg, Kansas. A tornado struck Sweetwater, Oklahoma, about 8:15 p.m. Saturday, causing major damage to a high school and other buildings. "The tornado came through and just dead-center punched Sweetwater," Roger Mills County Sheriff Joe Hay told KOCO-TV in Oklahoma City. He said there was extensive damage but just one minor injury in the small town. The storm continued to grind north through northwestern Oklahoma toward Kansas for more than 45 minutes. More than 60 tornado touchdowns were reported on Saturday -- 40 of them between 6 and 9 p.m., the National Weather Service's Storm Prediction Center said. KOCO's Matt Leinbauer reported seeing damage from another confirmed tornado just east of Arnett, Oklahoma.
