URGENT - IMMEDIATE BROADCAST REQUESTED
TORNADO WATCH NUMBER 370
NWS STORM PREDICTION CENTER NORMAN OK
1110 AM CDT WED MAY 25 2011

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

       SOUTHERN ILLINOIS
       SOUTHERN INDIANA
       WESTERN AND CENTRAL KENTUCKY
       EASTERN MISSOURI

EFFECTIVE THIS WEDNESDAY MORNING AND EVENING FROM 1110 AM UNTIL
900 PM CDT.

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

DESTRUCTIVE TORNADOES...LARGE HAIL TO 3 INCHES IN DIAMETER...
THUNDERSTORM WIND GUSTS TO 70 MPH...AND DANGEROUS LIGHTNING ARE
POSSIBLE IN THESE AREAS.

THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 75 STATUTE
MILES NORTH AND SOUTH OF A LINE FROM 45 MILES WEST OF FARMINGTON
MISSOURI TO 40 MILES SOUTH SOUTHEAST OF LOUISVILLE KENTUCKY.  FOR
A COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH
OUTLINE UPDATE (WOUS64 KWNS WOU0).

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 WARNINGS.

OTHER WATCH INFORMATION...CONTINUE...WW 367...WW 368...WW 369...

DISCUSSION...AN OUTBREAK OF TORNADOES --SOME POTENTIALLY STRONG TO
VIOLENT AND LONG-TRACKED-- IS EXPECTED ACROSS THE WATCH AREA TODAY
IN ASSOCIATION WITH MULTIPLE WAVES OF SUPERCELLS.  THE COMBINATION
OF A VERY MOIST BOUNDARY LAYER AND DAYTIME HEATING WILL CONTRIBUTE
TO A BROAD...MODERATELY TO STRONGLY UNSTABLE WARM SECTOR WITH MLCAPE
VALUES OF 1500-3500 J/KG.  THIS INSTABILITY WILL COINCIDE WITH 50-60
KT OF DEEP SWLY SHEAR AND EFFECTIVE SRH OF 300-500 M2/S2...RESULTING
IN A VOLATILE ENVIRONMENT QUITE FAVORABLE FOR LONG-LIVED SUPERCELLS.

AVIATION...TORNADOES AND A FEW SEVERE THUNDERSTORMS WITH HAIL
SURFACE AND ALOFT TO 3 INCHES. EXTREME TURBULENCE AND SURFACE
WIND GUSTS TO 60 KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO
600. MEAN STORM MOTION VECTOR 24035.
