Gov. Bill Haslam's office says all state offices across Tennessee will be closed on Friday. A previous statement said offices in Middle and East Tennessee would be open for a half-day, but Haslam spokeswoman Jennifer Donnals said conditions deteriorated earlier than was forecast. Snow was falling across many areas in Tennessee before sunrise. The Tennessee Department of Transportation warned motorists to drive with caution due to slick conditions. Forecasters say snow and sleet accumulations could reach 4 to 6 inches in West Tennessee while 3 to 6 inches is predicted in Middle and East Tennessee.
