   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 350
   CONTINUES.
   
   SEVERE TSTM WATCH 350 CONTINUES UNTIL 09Z. IN ADDITION TO LOCALLY
   HEAVY RAINFALL...SEVERE HAIL REMAINS A POSSIBILITY...WITH DAMAGING
   WINDS ALSO POSSIBLE AS WELL ON AN ISOLATED BASIS MAINLY ACROSS
   EASTERN/SOUTHERN AR.
   
   AIDED BY AN EXISTING COLD POOL/ASSOCIATED BUBBLE HIGH...ONGOING
   QUASI-LINEAR CONVECTIVE COMPLEX ACROSS SOUTHERN AR IS EXPECTED TO
   CONTINUE A SOUTHEASTWARD PROPAGATION ACROSS EASTERN/SOUTHERN AR OVER
   THE NEXT SEVERAL HOURS. LOCALLY HEAVY RAINFALL WILL LIKELY BE THE
   DOMINANT CONCERN...ALTHOUGH AN ISOLATED DAMAGING WIND POTENTIAL
   REMAINS. FARTHER WEST-NORTHWEST...OTHER STRONG/POTENTIALLY SEVERE
   TSTMS CAPABLE OF HAIL WILL LIKELY CONTINUE TO DEVELOP AS A
   SOUTH-SOUTHWESTERLY LOW LEVEL JET INTERACTS WITH A CONVECTIVELY
   INDUCED COLD POOL THAT EXTENDS NORTHWEST TO SOUTHEAST FROM
   NORTH-CENTRAL OK INTO CENTRAL AR. GIVEN THE PROXIMITY OF STEEP LAPSE
   RATES/STRONG ELEVATED INSTABILITY /AS PER THE 00Z NORMAN OBSERVED
   RAOB/...SEVERE HAIL REMAINS POSSIBLE OVERNIGHT.
