   VALID 130825Z - 130930Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 396
   CONTINUES.
   
   AN ISOLATED SEVERE THREAT ONGOING IN THE SERN PART OF WW 395 WILL
   LIKELY CONTINUE SEWD INTO THE SRN PART OF WW 396 TOWARD DAYBREAK.
   LARGE HAIL AND ISOLATED WIND DAMAGE WILL LIKELY BE THE PRIMARY
   THREATS WITH THE ACTIVITY.
   
   A SMALL CONVECTIVE CLUSTER IS ONGOING JUST SOUTH OF A
   QUASI-STATIONARY FRONTAL BOUNDARY EXTENDING SEWD ACROSS ERN OK INTO
   CNTRL AR. OBJECTIVE ANALYSIS SHOWS MODERATE INSTABILITY ALONG AND
   SOUTH OF THE BOUNDARY WITH MLCAPE VALUES RANGING FROM 1500 TO 3000
   J/KG. THIS SHOULD FUEL THE CLUSTER SEWD INTO SRN AR OVER THE NEXT
   FEW HOURS. THE EXIT REGION OF A MID-LEVEL JET OVER WRN AR WILL
   CREATE ENOUGH VERTICAL SHEAR TO MAINTAIN STORM ORGANIZATION WITH A
   THREAT FOR LARGE HAIL. ALTHOUGH THE STORMS SHOULD BE SLIGHTLY
   ELEVATED...A FEW STRONG WIND GUSTS MAY ALSO OCCUR.
