LATE WEDNESDAY EVENING...A LINE OF SEVERE THUNDERSTORMS WAS RAPIDLY MOVING EAST...IN EXCESS OF 50 MPH...ACROSS CENTRAL TENNESSEE. THE LINE WILL GRADUALLY WEAKEN AS IT MOVES EAST INTO COOLER...MORE STABLE AIR. HOWEVER...AS THE LINE ENTERS THE WESTERN NORTH CAROLINA MOUNTAINS SHORTLY AFTER MIDNIGHT...DAMAGING WINDS WILL STILL BE POSSIBLE. HIGHER ELEVATIONS IN THE SOUTHWEST MOUNTAIN COUNTIES OF GRAHAM...SWAIN AND MACON WILL BE MOST AT RISK. THE FACT THAT ENVIRONMENTAL WINDS WILL ALREADY BE STRONG AHEAD OF A COLD FRONT WILL HELP TO AUGMENT THE STRONG WINDS ASSOCIATED WITH THE LINE OF STORMS. IF THE LINE IS A LITTLE STRONGER THAN ANTICIPATED AS IT ENTERS THE MOUNTAINS...DAMAGING WINDS WOULD EXTEND AS FAR EAST AS ASHEVILLE...AND INTO THE NORTHERN MOUNTAINS. DISPATCHERS SHOULD ENSURE COUNTY EMERGENCY MANAGEMENT OFFICIALS ARE AWARE OF THIS INFORMATION. MCAVOY
