ATLANTA – Temperatures plummeted late Monday, turning slushy streets into sheets of ice across Southern states that are more accustomed to sunshine than snow. The wintry blast has grounded flights, cut power to thousands of homes and even forced Auburn University to cancel viewing parties for the national championship bowl game. Snow ranging from several inches to more than a foot blanketed states from Louisiana to the Carolinas – a region where many cities have only a handful of snowplows, if any. In many areas, the snow began turning to freezing rain, making roads even more treacherous.
