AREAS AFFECTED...PARTS OF MO

CONCERNING...TORNADO WATCH 216...

VALID 262156Z - 262330Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 216 CONTINUES.

SUMMARY...GREATEST SEVERE THREAT WITHIN WW 216 EXISTS NEAR AND
SOUTHEAST OF THE KANSAS CITY METRO AREA WHERE ALL HAZARDS REMAIN
POSSIBLE. ADDITIONAL STORMS FORMING DOWNSTREAM OF WW 216 IN CENTRAL
MO SHOULD POSE A RISK FOR ISOLATED LARGE HAIL AND STRONG WINDS...AND
THIS REGION IS BEING MONITORED FOR A POSSIBLE WW.

DISCUSSION...A FEW SUPERCELLS ARE ONGOING NEAR AND SOUTHEAST OF THE
KANSAS CITY METRO AREA. THIS ACTIVITY IS OCCURRING ALONG A REMNANT
LARGE-SCALE OUTFLOW BOUNDARY. EAX VWP DATA SAMPLED A VEERING WIND
PROFILE WITH HEIGHT SUPPORTIVE OF ALL HAZARDS. OVER NORTHEAST
MO...DRIER SURFACE DEW POINTS RESULTING TEMPERATURE/DEW POINT
SPREADS UP TO 30 DEG F SUGGEST THE TORNADO RISK IS LIKELY MAXIMIZED
SHORT-TERM. FARTHER SOUTHEAST...CONVECTION HAS INCREASED OUTSIDE OF
WW 216. SGF VWP DATA SAMPLED MUCH WEAKER 2-5 KM AGL WINDS SUGGESTING
STORMS TO THE SOUTHEAST WILL STRUGGLE TO BECOME ORGANIZED.
STILL...GIVEN MLCAPE OF 3000-3500 J/KG ACROSS SOUTHWEST
MO...ISOLATED LARGE HAIL AND STRONG WIND GUSTS MAY OCCUR.
