0417 AM CST MON FEB 28 2011

...SIGNIFICANT SEVERE THUNDERSTORMS EXPECTED OVER PARTS OF THE
TENNESSEE VALLEY INTO SOUTHERN APPALACHIANS TODAY...

THE NWS STORM PREDICTION CENTER IN NORMAN OKLAHOMA IS FORECASTING
THE DEVELOPMENT OF POTENTIALLY WIDESPREAD DAMAGING WINDS AND A FEW
STRONG TORNADOES OVER PARTS OF THE TENNESSEE VALLEY AND SOUTHERN
APPALACHIANS TODAY.

THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE

       NORTHERN ALABAMA
       NORTHWEST GEORGIA
       MIDDLE AND EASTERN TENNESSEE

ELSEWHERE...SEVERE STORMS ARE ALSO POSSIBLE FROM THE LOWER
MISSISSIPPI VALLEY AND LOWER OHIO VALLEY TO THE THE MIDDLE AND
SOUTHEAST ATLANTIC COASTS.

AN UPPER-LEVEL STORM SYSTEM OVER THE CENTRAL AND SOUTHERN PLAINS
EARLY THIS MORNING WILL ACCELERATE RAPIDLY EAST THROUGH THE MID AND
LOWER MISSISSIPPI AND TENNESSEE VALLEYS TODAY AND EVENTUALLY OFF THE
ATLANTIC COAST BY TUESDAY MORNING.  A COLD FRONT WILL ACCOMPANY THIS
STORM SYSTEM EAST WITH THIS BOUNDARY SERVING AS THE FOCUS FOR SEVERE
THUNDERSTORM DEVELOPMENT TODAY INTO TONIGHT.

STRONG SOUTHWEST WINDS JUST ABOVE THE GROUND HAVE ALLOWED A WARM AND
HUMID AIR MASS TO PROGRESS NORTH FROM THE GULF OF MEXICO INTO THE
OHIO VALLEY IN ADVANCE OF THIS STORM SYSTEM.  AS A RESULT...
CONDITIONS OVER A LARGE AREA HAVE BECOME FAVORABLE FOR THE
DEVELOPMENT OF STRONG TO SEVERE THUNDERSTORMS.  THE GREATEST RISK
FOR POTENTIALLY WIDESPREAD DAMAGING WINDS AND A FEW STRONG TORNADOES
IS EXPECTED TO DEVELOP ACROSS THE TENNESSEE VALLEY AND THE SOUTHERN
APPALACHIANS TODAY AS THE UPPER-LEVEL STORM SYSTEM AND SURFACE COLD
FRONT INTERACT WITH THE UNSTABLE ATMOSPHERE.

A RISK FOR SEVERE THUNDERSTORMS CAPABLE OF MAINLY DAMAGING WINDS
WILL CONTINUE LATER TODAY INTO TONIGHT EAST OF THE APPALACHIANS AS
WELL AS ACROSS PORTIONS OF THE CENTRAL AND EASTERN GULF STATES.

STATE AND LOCAL EMERGENCY MANAGERS ARE MONITORING THIS DEVELOPING
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
