          WESTERN KENTUCKY
          SOUTHEAST MISSOURI INCLUDING THE BOOTHEEL
          NORTHWEST MISSISSIPPI
          WEST TENNESSEE
   
   EFFECTIVE THIS TUESDAY AFTERNOON AND EVENING FROM 305 PM UNTIL
   1000 PM CDT.
   
   ...THIS IS A PARTICULARLY DANGEROUS SITUATION...
   
   DESTRUCTIVE TORNADOES...LARGE HAIL TO 2.5 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 70 STATUTE
   MILES EAST AND WEST OF A LINE FROM 75 MILES NORTH OF FORT
   CAMPBELL KENTUCKY TO 35 MILES EAST OF EL DORADO ARKANSAS.  FOR A
   COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH OUTLINE
   UPDATE (WOUS64 KWNS WOU7).
   
   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.

   215...WW 216...
   
   DISCUSSION...THUNDERSTORMS ARE INTENSIFYING ALONG A WEAK SURFACE
   BOUNDARY EXTENDING FROM CENTRAL AR INTO WESTERN KY.  A FEW OF THESE
   INITIAL STORMS WILL LIKELY BECOME SUPERCELLS WITH A RISK OF LARGE
   HAIL...DAMAGING WINDS...AND ISOLATED TORNADOES.  THE RISK OF
   SIGNIFICANT SEVERE WEATHER WILL INCREASE THROUGH THE EVENING AS
   STORMS FORM TO THE SOUTHWEST AND MOVE INTO THE WATCH AREA.  VERY
   STRONG SHEAR PROFILES DURING THE LATTER HALF OF THE WATCH PERIOD
   SUGGEST THAT PDS WORDING IS APPROPRIATE...WITH STRONG TORNADOES
   POSSIBLE.
