   MESOSCALE DISCUSSION 1334
   NWS STORM PREDICTION CENTER NORMAN OK
   1107 PM CDT WED JUL 08 2015

   AREAS AFFECTED...SRN TX PANHANDLE

   CONCERNING...SEVERE THUNDERSTORM WATCH 395...

   VALID 090407Z - 090500Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 395
   CONTINUES.

   SUMMARY...WW 395 IS SCHEDULED TO EXPIRE AT 05Z. BASED ON RECENT
   OBSERVATIONAL TRENDS...AN ADDITIONAL WW OR LOCAL TEMPORAL EXTENSION
   APPEARS UNLIKELY.

   DISCUSSION...EARLIER SUPERCELLS HAVE WEAKENED SUBSTANTIALLY DURING
   THE PAST HOUR WITHIN A GENERAL CLUSTER MODE AND INCREASINGLY ELY
   COMPONENT TO OVERALL MOVEMENT. PER ENLARGED GROUND CLUTTER PATTERNS
   IN LBB/FDR RADARS...IT APPEARS THAT INCREASING MLCIN HAS
   SUFFICIENTLY DISRUPTED SUSTENANCE OF LOW-LEVEL MESOCYCLONES AMID
   BOUNDARY-LAYER DECOUPLING. ELEVATED CONVECTION MAY PERSIST FOR THE
   NEXT SEVERAL HOURS WITH LOW-LEVEL WAA ATOP REMNANT CONVECTIVE
   OUTFLOW. ISOLATED SEVERE HAIL MIGHT ACCOMPANY THE WRN FRINGE OF THIS
   DEVELOPMENT OWING TO CLOSER PROXIMITY TO STEEPER MID-LEVEL LAPSE
   RATES. BUT THE OVERALL SEVERE RISK APPEARS UNLIKELY TO GREATLY
   INTENSIFY BEYOND MIDNIGHT.
