   PUBLIC SEVERE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   1226 PM CDT WED APR 27 2011
   
   ...OUTBREAK OF TORNADOES AND SEVERE THUNDERSTORMS EXPECTED OVER
   PARTS OF THE TENNESSEE VALLEY...SOUTHERN APPALACHIAN MOUNTAINS AND
   SOUTHERN OHIO VALLEY THIS AFTERNOON THROUGH TONIGHT...
   
   THE NATIONAL WEATHER SERVICE STORM PREDICTION CENTER IN NORMAN
   OKLAHOMA IS FORECASTING THE DEVELOPMENT OF NUMEROUS TORNADIC STORMS
   WITH A FEW STRONG TO VIOLENT...LONG-TRACK TORNADOES OVER PARTS OF
   THE TENNESSEE VALLEY AND SOUTHERN APPALACHIAN MOUNTAINS. THE THREAT
   FOR TORNADIC STORMS SHOULD ALSO EXTEND NORTHWARD INTO THE SOUTHERN
   OHIO VALLEY THIS AFTERNOON THROUGH TONIGHT.
   
   THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE
   
          NORTHERN AND CENTRAL ALABAMA
          FAR NORTHWESTERN GEORGIA
          EASTERN MISSISSIPPI
          SOUTHERN TENNESSEE
   
   ELSEWHERE...SEVERE THUNDERSTORMS ARE ALSO POSSIBLE FROM THE CENTRAL
   AND EASTERN GULF COAST STATES NORTHEASTWARD ACROSS THE OHIO
   VALLEY...CAROLINAS...CENTRAL TO NORTHERN APPALACHIAN MOUNTAINS AND
   MIDDLE-ATLANTIC.
   
   STRONG THUNDERSTORMS WILL CONTINUE TO DEVELOP OVER PARTS OF THE
   LOWER MISSISSIPPI VALLEY AND TENNESSEE VALLEY THIS AFTERNOON AHEAD
   OF A POWERFUL STORM SYSTEM CURRENTLY ENTERING THE REGION FROM THE
   WEST. THE STORMS WILL QUICKLY MOVE EAST TO  NORTHEASTWARD OVER THE
   TENNESSEE AND OHIO VALLEYS INTO THE SOUTHERN APPALACHIAN MOUNTAINS
   THIS AFTERNOON AND EVENING. AS THE THUNDERSTORMS ENCOUNTER A VERY
   MOIST UNSTABLE AIR MASS AND INTERACT WITH STRONG WIND SHEAR...THE
   RAPID DEVELOPMENT OF SEVERE STORMS WILL OCCUR. A POTENTIAL FOR
   STRONG TO VIOLENT...LONG-TRACK TORNADOES WILL EXIST IN THE TENNESSEE
   VALLEY AND SOUTHERN APPALACHIAN MOUNTAINS. NUMEROUS TORNADIC STORMS
   WITH LARGE HAIL...AND WIDESPREAD DAMAGING WINDS WILL ALSO BE
   POSSIBLE ACROSS THE REMAINDER OF THE OHIO VALLEY AND CENTRAL GULF
   COAST STATES. ADDITIONAL STRONG TO SEVERE THUNDERSTORMS ARE FORECAST
   TO DEVELOP FROM THE OHIO VALLEY AND CAROLINAS NORTHEASTWARD INTO THE
   CENTRAL TO NORTHERN APPALACHIAN MOUNTAINS BY THE OVERNIGHT PERIOD. 
   
   THE MOST INTENSE STORMS ARE EXPECTED ACROSS NORTHERN ALABAMA...FAR
   NORTHWESTERN GEORGIA...NORTHEASTERN MISSISSIPPI...AND SOUTHERN
   TENNESSEE. A HIGH RISK FOR DAMAGING TORNADIC THUNDERSTORMS IS IN
   EFFECT FOR THESE AREAS. FUTURE FORECASTS MAY EXPAND THIS AREA TO
   INCLUDE PORTIONS OF EASTERN TENNESSEE...AS WELL AS AREAS FARTHER
   SOUTH INTO EASTERN MISSISSIPPI AND WESTERN ALABAMA.
   
   STATE AND LOCAL EMERGENCY MANAGERS ARE MONITORING THIS POTENTIALLY
   VERY DANGEROUS SITUATION. THOSE IN THE THREATENED AREA ARE URGED TO
   REVIEW SEVERE WEATHER SAFETY RULES AND TO LISTEN TO
   RADIO...TELEVISION...AND NOAA WEATHER RADIO FOR POSSIBLE
   WATCHES...WARNINGS...AND STATEMENTS LATER TODAY.
