AREAS AFFECTED...SWRN MO...NWRN  AR...NERN OK

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 211823Z - 211930Z

...SEVERE THUNDERSTORM WATCH WILL BE ISSUED SOON FOR PORTIONS OF
SWRN/CNTRL MO...NWRN AR...NERN OK...

LOW LEVEL WARM ADVECTION APPEARS RESPONSIBLE FOR RECENT INCREASE IN
SHOWERS-ISOLATED THUNDERSTORMS ACROSS NERN OK. THIS ACTIVITY SHOULD
CONTINUE TO INCREASE IN INTENSITY AS BOUNDARY LAYER
WARMS/DESTABILIZED DOWNSTREAM ACROSS SWRN MO/NWRN AR.  ALTHOUGH
VERTICAL SHEAR IS NOT PARTICULARLY STRONG...SUFFICIENT VEERING
THROUGH A DEEP LAYER ON 18Z SGF SOUNDING DOES SUGGEST SOME
ORGANIZATIONAL POTENTIAL...ESPECIALLY GIVEN THE MODERATE
INSTABILITY.  SEVERE THUNDERSTORM WATCH WILL BE ISSUED SOON TO
ADDRESS THIS DEVELOPING SCENARIO.
