PUBLIC SEVERE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0330 AM CST THU FEB 24 2011

...SEVERE THUNDERSTORMS EXPECTED OVER PARTS OF THE LOWER
MISSISSIPPI...LOWER TENNESSEE...AND LOWER OHIO VALLEYS LATER TODAY
INTO TONIGHT...

THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE
DEVELOPMENT OF TORNADOES...DAMAGING WINDS...AND HAIL OVER PARTS OF
THE LOWER MISSISSIPPI AND LOWER TENNESSEE VALLEYS LATER TODAY INTO
TONIGHT.

THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE

       MUCH OF ARKANSAS
       WESTERN KENTUCKY
       NORTHERN MISSISSIPPI
       WESTERN AND MIDDLE TENNESSEE

SURROUNDING THE AREA OF GREATEST RISK...SEVERE STORMS ALSO MAY OCCUR
FROM NORTHERN AND EASTERN TEXAS...AND CENTRAL AND EASTERN
OKLAHOMA...INTO ALABAMA AND THE WESTERN SLOPES OF THE SOUTHERN AND
CENTRAL APPALACHIANS

A POTENT JET STREAM DISTURBANCE NOW IN NEW MEXICO WILL SWEEP
EAST-NORTHEAST ACROSS THE SOUTHERN PLAINS TODAY...AND INTO THE LOWER
MISSISSIPPI AND OHIO VALLEYS TONIGHT AND EARLY FRIDAY.

AS THIS OCCURS...A SURFACE LOW NOW FORMING IN OKLAHOMA WILL
STRENGTHEN AND ACCELERATE EAST-NORTHEAST INTO NORTHWEST ARKANSAS
THIS AFTERNOON...BEFORE CONTINUING NORTHEAST ACROSS KENTUCKY AND
SOUTHERN OHIO EARLY FRIDAY.

A BROAD CURRENT OF MOIST AND INCREASINGLY UNSTABLE AIR WILL SURGE
NORTHWARD AHEAD OF THE LOW INTO MUCH OF SOUTH-CENTRAL AND
SOUTHEASTERN UNITED STATES.

THE COMBINATION OF INCREASING MOISTURE AND INSTABILITY WITH THE
STRENGTHENING WINDS OF THE JET STREAM WILL CREATE AN ENVIRONMENT
FAVORABLE FOR STRONG ROTATING THUNDERSTORMS AS DAYTIME HEATING
FURTHER DESTABILIZES THE REGION FROM THE ARKLATEX TO THE LOWER
TENNESSEE VALLEY.

THE STORMS WILL HAVE THE POTENTIAL TO GROW INTO ONE OR MORE
LONG-LIVED BANDS THAT COULD PRODUCE A FEW STRONG TORNADOES...IN
ADDITION TO SWATHS OF DAMAGING WIND AND HAIL.

THE THUNDERSTORMS SHOULD BE THE MOST NUMEROUS LATER THIS AFTERNOON
THROUGH EARLY TONIGHT OVER PARTS OF ARKANSAS...MISSISSIPPI AND
TENNESSEE...BUT MORE ISOLATED SEVERE WEATHER MAY PERSIST THROUGH
EARLY FRIDAY OVER PARTS OF THE TENNESSEE AND OHIO VALLEYS.

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
TODAY.
