LITTLE TEMPERATURE CONTRAST ACROSS FRONTAL BOUNDARY. .LONG TERM...(SATURDAY NIGHT THROUGH THURSDAY)...THE WEAK FRONTAL BOUNDARY MOVING INTO THE SOUTHERN TN VALLEY LOSES ITS IDENTITY BY SUNDAY MORNING. CONFIDENCE IS LOW FOR SHOWERS AND THUNDERSTORMS OVERNIGHT GENERALLY FOR SOUTHERN AREAS BUT THIS WOULD BE THE BEST PLACE FOR ANY CONVECTION TO SPARK UP.

BEST CHANCE OCCUR ON TUESDAY WHEN THE RIDGE BREAKS DOWN OVER THE SE AND A SHORTWAVE TRANSLATES ACROSS THE GREAT LAKES REGION.
