   AREAS AFFECTED...S-CNTRL KS...NWRN THROUGH N-CNTRL OK...AND THE NERN
   TX PANHANDLE
   
   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 
   
   VALID 290459Z - 290600Z
   
   SMALL MCS OVER SWRN KS...NWRN OK AND NERN TX PANHANDLE WILL POSE AT
   LEAST A MODEST THREAT FOR ISOLATED STRONG TO DAMAGING WIND GUSTS AS
   IT DEVELOPS ESEWD NEXT COUPLE HOURS. OVERALL THREAT DOES NOT APPEAR
   PARTICULARLY ROBUST...AND UNLESS TRENDS BEGIN TO SUGGEST A MORE
   SUSTAINED SEVERE RISK...A WW WILL PROBABLY NOT BE NEEDED.
   
   SMALL MCS FROM SWRN KS THROUGH NWRN OK AND THE NERN TX PANHANDLE IS
   MOVING SEWD AT AROUND 30 KT. THE STORMS ARE MOVING INTO A BOUNDARY
   LAYER THAT IS MOIST...BUT HAS BEEN STABILIZED BY NOCTURNAL COOLING
   AND CONTAINS A SIGNIFICANT AMOUNT OF SURFACE BASED CONVECTIVE
   INHIBITION. HOWEVER...INFLOW INTO THE STORMS IS SITUATED ABOVE THE
   SURFACE ALONG A 25-30 KT SLY LLJ. THIS ALONG WITH THE CIRCULATION
   ASSOCIATED WITH THE ATTENDANT MCV WILL LIKELY HELP TO SUSTAIN THE
   ACTIVITY NEXT FEW HOURS. STORMS ARE EMBEDDED WITHIN MODEST
   INSTABILITY AND NWLY FLOW ALOFT AOB 25 KT...AND THE OVERALL
   ENVIRONMENT APPEARS ONLY MARGINALLY SUPPORTIVE OF SEVERE STORMS.
   NEVERTHELESS...THE DRY SUB-CLOUD LAYER COULD PROMOTE ISOLATED STRONG
   WIND GUSTS AS ACTIVITY DEVELOPS SEWD.
