   PUBLIC SEVERE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   1030 AM CST WED FEB 18 2009
   
   ...SIGNIFICANT SEVERE THUNDERSTORMS EXPECTED OVER PARTS OF THE GULF
   COAST STATES THIS AFTERNOON AND TONIGHT...
   
   THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE
   DEVELOPMENT OF DAMAGING WINDS AND PERHAPS A COUPLE STRONG TORNADOES
   OVER PARTS OF THE GULF COAST STATES THIS AFTERNOON AND TONIGHT.
   
   THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE
   
          CENTRAL AND SOUTHERN ALABAMA
          WESTERN FLORIDA PANHANDLE
          SOUTHWEST GEORGIA
          SOUTHEAST LOUISIANA
          SOUTHEAST MISSISSIPPI
   
   ELSEWHERE...SEVERE STORMS ARE ALSO POSSIBLE FROM THE CUMBERLAND
   PLATEAU REGION SWD THROUGH THE GULF COAST STATES...
   
   STRONG SOUTHWESTERLY WINDS ABOVE THE GROUND ARE TRANSPORTING AN
   INCREASINGLY MOIST AIR MASS NEWD ACROSS THE GULF COAST STATES AND TN
   VALLEY TODAY.  THIS MOISTURE WILL COMBINE WITH DAYTIME HEATING TO
   SUPPORT A MODERATELY UNSTABLE AIR MASS IN ADVANCE OF A COLD FRONT
   WHICH WILL PUSH EWD/SEWD ACROSS THE TN VALLEY AND GULF COAST STATES
   THIS AFTERNOON AND TONIGHT.
   
   THE COLD FRONT IN CONJUNCTION WITH A STRONG JET STREAM ALOFT WILL
   RESULT IN THE DEVELOPMENT OF SEVERE THUNDERSTORMS BOTH ALONG THE
   COLD FRONT AS WELL AS FARTHER EAST WITHIN THE DESTABILIZING WARM
   SECTOR.  WIND PROFILES WILL BE SUPPORTIVE OF BOTH SUPERCELL AND BOW
   ECHO STORM STRUCTURES CAPABLE OF DAMAGING WINDS...LARGE HAIL AND
   TORNADOES.  THIS SEVERE WEATHER THREAT APPEARS TO BE GREATEST FROM
   LATE THIS AFTERNOON INTO TONIGHT ACROSS THE MODERATE RISK AREA WHERE
   THE POTENTIAL WILL EXIST FOR MORE WIDESPREAD WIND DAMAGE.
   
   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.
