   URGENT - IMMEDIATE BROADCAST REQUESTED
   SEVERE THUNDERSTORM WATCH NUMBER 450
   NWS STORM PREDICTION CENTER NORMAN OK
   1010 AM CDT SUN JUL 11 2010
   
   THE NWS STORM PREDICTION CENTER HAS ISSUED A
   SEVERE THUNDERSTORM WATCH FOR PORTIONS OF 
   
          PART OF EASTERN KANSAS
          MUCH OF CENTRAL AND SOUTHERN MISSOURI
   
   EFFECTIVE THIS SUNDAY MORNING AND AFTERNOON FROM 1010 AM UNTIL
   400 PM CDT.
   
   HAIL TO 2 INCHES IN DIAMETER...THUNDERSTORM WIND GUSTS TO 70
   MPH...AND DANGEROUS LIGHTNING ARE POSSIBLE IN THESE AREAS.
   
   THE SEVERE THUNDERSTORM WATCH AREA IS APPROXIMATELY ALONG AND 65
   STATUTE MILES NORTH AND SOUTH OF A LINE FROM 40 MILES NORTHWEST
   OF CHANUTE KANSAS TO 40 MILES SOUTHEAST OF FARMINGTON MISSOURI. 
   FOR A COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH
   OUTLINE UPDATE (WOUS64 KWNS WOU0).
   
   REMEMBER...A SEVERE THUNDERSTORM WATCH MEANS CONDITIONS ARE
   FAVORABLE FOR 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. SEVERE THUNDERSTORMS CAN AND OCCASIONALLY
   DO PRODUCE TORNADOES.
   
   DISCUSSION...INITIAL MCS DEVELOPMENT APPEARS TO BE UNDERWAY THIS
   MORNING SE OF MKC IN CONJUNCTION WITH A PROGRESSIVE SHORT WAVE
   TROUGH AND SEASONABLY STRONG MID AND HIGH-LEVEL WIND FIELD.  THIS
   CONVECTIVE SYSTEM IS EXPECTED TO MOVE/DEVELOP SEWD ALONG THE
   IMMEDIATE COOL SIDE OF A QUASI-STATIONARY BOUNDARY EXTENDING FROM
   THE INTERSECTION WITH THE MCS INTO THE MO BOOTHEEL AND NWRN TN.  THE
   COMBINATION OF STEEP LAPSE RATES...RICH BOUNDARY LAYER MOISTURE AND
   40-45 KT OF DEEP-LAYER SHEAR SHOULD SUPPORT THE DEVELOPMENT OF A
   WELL-ORGANIZED BOWING COMPLEX WITH THE THREAT FOR DAMAGING WINDS AND
   LARGE HAIL.
   ADDITIONAL STORMS ARE ALSO EXPECTED TO FORM ALONG THE WRN FLANK OF
   MCS THIS AFTERNOON ACROSS ERN KS WITHIN A SIMILAR THERMODYNAMIC AND
   KINEMATIC ENVIRONMENT WHERE AN ASSOCIATED RISK FOR LARGE HAIL AND
   DAMAGING WIND GUSTS WILL EXIST.
   
   AVIATION...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. MEAN STORM
   MOTION VECTOR 29040.
