   ESEWD THROUGH THE NIGHT BEING MAINTAINED BENEATH RIGHT REAR QUADRANT

   WITH MOIST SYMMETRIC INSTABILITY SHOULD CONTINUE TO PROMOTE ELEVATED
   TSTM FORMATION ACROSS THE REGION THROUGH SATURDAY MORNING.
   
   ...SRN PLAINS/OZARKS...
   COLD FRONT WAS CURRENTLY SITUATED FROM NERN MO SWWD INTO CNTRL AND
   SWRN OK. EVENING SOUNDINGS WERE SHOWING PREFRONTAL AIRMASS REMAINED
   WARM AND DRY WITH STRONG CONVECTIVE INHIBITION AND ONLY MARGINAL
   MLCAPE ON THE ORDER OF 250-500 J/KG. MODELS ARE IN GOOD AGREEMENT
   THAT FORCED ASCENT AND MOISTENING WITHIN THE POST FRONTAL
   ENVIRONMENT LATER TONIGHT WILL BE ADEQUATE FOR TSTM DEVELOPMENT WITH
   STORM UPDRAFTS ROOTED ABOVE 850MB. THIS ACTIVITY SHOULD SPREAD INTO
   SRN MO/NRN AR...AND NERN OK THROUGH DAYBREAK. SEVERE WEATHER
   POTENTIAL CONTINUES TO APPEAR QUITE LIMITED BASED ON ELEVATED NATURE
   OF THE CONVECTION AND WEAK INSTABILITY.
