   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 198
   CONTINUES.
   
   THREAT FOR ISOLATED LARGE HAIL AND POSSIBLY ISOLATED STRONG WIND
   GUSTS CONTINUE ACROSS N-CNTRL TX. THREAT COULD EVENTUALLY SPREAD
   INTO NERN TX.
   
   QUASI-STATIONARY FRONT EXTENDS FROM CNTRL AR WSWWD ALONG RED RIVER
   AREA INTO WRN TX. WHAT IS LEFT OF STORMS THAT DEVELOPED SUNDAY
   EVENING CONTINUE OVER N-CNTRL TX. HOWEVER...TREND HAS BEEN FOR MOST
   STORMS TO GRADUALLY WEAKEN. ACTIVITY IS MOVING THROUGH WARM SECTOR
   TO THE SOUTH OF BAROCLINIC ZONE LOCATED ALONG THE RED RIVER. IT IS
   NOT CLEAR WHETHER THE STRONG STORM RELATIVE INFLOW AND CONVERGENCE
   ASSOCIATED WITH THE STRONG LLJ INTERACTING WITH THE CONVECTIVE
   OUTFLOW BOUNDARIES WILL BE SUFFICIENT TO MAINTAIN STORMS INTO NERN
   TX GIVEN CINH ASSOCIATED WITH EML ABOVE THE STABLE BOUNDARY LAYER.
   NEVERTHELESS BEHAVIOR OF STORMS NEAR THE RED RIVER AREA SUGGEST AT
   LEAST SOME POTENTIAL EXISTS FOR ACTIVITY TO TRANSITION INTO A
   FORWARD PROPAGATING MCS. IF THIS OCCURS THE THREAT FOR ISOLATED
   DAMAGING WIND WOULD INCREASE.
