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.
First PDS of the day?
ISOLATED SUPERCELL THREAT MAY TRANSITION RAPIDLY TO EVOLUTION OF SQUALL LINE...BUT THREAT OF ISOLATED STRONG TORNADOES EXISTS.
Can you decipher?
