NWS STORM PREDICTION CENTER NORMAN OK
1050 AM CDT SUN MAY 30 2004

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

       NORTHERN AND WESTERN ARKANSAS
       EXTREME EASTERN KANSAS
       A LARGE PART OF MISSOURI
       EASTERN OKLAHOMA

EFFECTIVE THIS SUNDAY MORNING AND EVENING FROM 1050 AM UNTIL 700
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 ALONG AND 95 STATUTE MILES EAST AND WEST
OF A LINE FROM 35 MILES NORTH NORTHEAST OF KIRKSVILLE MISSOURI TO
40 MILES SOUTH OF FORT SMITH ARKANSAS.

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 329...

DISCUSSION...SUPERCELLS EXPECTED TO DEVELOP IN THE NEXT 1-2 HOURS
ALONG COLD FRONT/DRY LINE BOUNDARY IN EXTREME ERN KS/WRN MO...WITH
SWD DEVELOPMENT ALONG THE BOUNDARIES INTO ERN OK.  OTHER STORMS MAY
FORM INVOF RETREATING W/E OUTFLOW BOUNDARY IN NRN MO.  COMBINATION
OF SURFACE HEATING...WEAK MID LEVEL COLD ADVECTION AND LARGE SCALE
ASCENT ASSOCIATED WITH LEADING EDGE OF WRN KS UPPER IMPULSE LIKELY
TO ALLOW CAP TO BE BROKEN WHERE LOW LEVEL UPLIFT IS STRONGEST. 
WHILE STORMS MAY TEND TO EVOLVE INTO NNE/SSW ORIENTED BANDS...
STRENGTH OF SHEAR AND INSTABILITY SUGGEST GOOD CHANCE FOR LONG-LIVED
SUPERCELLS WITH TORNADOES/LARGE HAIL AND HIGH WIND.
