URGENT - IMMEDIATE BROADCAST REQUESTED
TORNADO WATCH NUMBER 251 
NWS STORM PREDICTION CENTER NORMAN OK 
935 AM CDT MON MAY 5 2003

THE NWS STORM PREDICTION CENTER HAS ISSUED A
TORNADO WATCH FOR PORTIONS OF 

       EASTERN AND NORTH CENTRAL ALABAMA
       NORTHERN MISSISSIPPI
       WESTERN AND MIDDLE TENNESSEE

EFFECTIVE THIS MONDAY MORNING AND AFTERNOON FROM 935 AM UNTIL 300
PM CDT.

...THIS IS A PARTICULARLY DANGEROUS SITUATION...

DESTRUCTIVE TORNADOES...LARGE HAIL TO 2 INCHES IN DIAMETER...
THUNDERSTORM WIND GUSTS TO 70 MPH...AND DANGEROUS LIGHTNING ARE
POSSIBLE IN THESE AREAS.

THE TORNADO WATCH AREA IS ALONG AND 115 STATUTE MILES EAST AND
WEST OF A LINE FROM 50 MILES NORTHWEST OF NASHVILLE TENNESSEE TO
65 MILES SOUTHEAST OF GREENWOOD MISSISSIPPI.

REMEMBER...A TORNADO WATCH MEANS CONDITIONS ARE FAVORABLE FOR
TORNADOES AND SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH AREA.
PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR THREATENING
WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS AND POSSIBLE

AM CDT. CONTINUE...WW 246...WW 249...WW 250...


DISCUSSION...THOUGH SHORTWAVE RIDGING WILL BUILD ACROSS WW THIS
AFTERNOON...WARM SECTOR AIR MASS WILL BECOME VERY UNSTABLE AND
WEAKLY CAPPED.	IN ADDITION...SHEAR PROFILES ARE RATHER STRONG AND
MORE THAN SUFFICIENT FOR TORNADIC SUPERCELLS ONCE STORMS BECOME MORE
SURFACE-BASED.	ANY TORNADO WHICH CAN OCCUR WILL HAVE
STRONG/DAMAGING POTENTIAL GIVEN THE POTENT COMBINATION OF
SHEAR...INSTABILITY AND LOW LCLS OVER THE REGION.

AVIATION...TORNADOES AND A FEW SEVERE THUNDERSTORMS WITH HAIL
SURFACE AND ALOFT TO 2 INCHES. EXTREME TURBULENCE AND SURFACE WIND
GUSTS TO 60 KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO 500.
