   VALID 260327Z - 260530Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 377 CONTINUES.
   
   RADAR TRENDS SUGGEST CONVECTIVE INHIBITION IS RESULTING IN A
   THINNING OUT OF STORM COVERAGE OVER LA INTO WRN MS. A FEW ISOLATED
   CELLS REMAIN...AND WILL HAVE THE POTENTIAL FOR LARGE HAIL AND GUSTY
   WINDS...AND PERHAPS A TORNADO BUT 00Z SOUNDINGS SHOW MARGINAL
   BOUNDARY LAYER RH.
   
   THE GREATEST THREAT FOR SEVERE WILL BE OVER NRN SECTIONS OF THE
   WATCH...IN CLOSER PROXIMITY TO THE LOW LEVEL JET CORE AND WHERE AN
   ORGANIZED LINE PERSISTS. HOWEVER...WITH TIME... OUTFLOW WITH THESE
   STORMS MAY UNDERCUT THEM AND COMBINE WITH CAPPING TO REDUCE
   COVERAGE. UNTIL THAT TIME...DAMAGING WINDS AND LARGE HAIL SHOULD BE
   THE MAIN THREATS...BUT WITH STRONG SHEAR PROFILES...TORNADOES WILL
   REMAIN POSSIBLE ESPECIALLY WITH ANY ISOLATED CELLS AWAY FROM
   OUTFLOW.
