   MESOSCALE DISCUSSION 1333
   NWS STORM PREDICTION CENTER NORMAN OK
   0915 PM CDT WED JUL 08 2015

   AREAS AFFECTED...SRN TX PANHANDLE

   CONCERNING...SEVERE THUNDERSTORM WATCH 395...

   VALID 090215Z - 090345Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 395
   CONTINUES.

   SUMMARY...A TRIO OF SUPERCELLS APPEAR TO BE GROWING UPSCALE WITH A
   PROBABLE TRANSITION IN THE PREDOMINANT SEVERE RISK FROM HAIL TO
   WIND. SEVERE RISK APPEARS MINIMAL N OF OLDHAM/POTTER/CARSON
   COUNTIES.

   DISCUSSION...A PAIR SUPERCELLS IN ERN OLDHAM TO POTTER COUNTIES
   APPEAR TO BE IN THE PROCESS OF CONSOLIDATING WITH FLANKING
   CONVECTION THAT RECENTLY FLARED UP OVER CNTRL OLDHAM COUNTY AND
   STORM-SCALE OUTFLOWS SURGING S OF THE ERN UPDRAFTS. LONE DISCRETE
   SUPERCELL ALONG THE DEAF SMITH/RANDALL COUNTY LINE MAY HAVE A LONGER
   DURATION HAIL AND BRIEF TORNADO RISK GIVEN THE MODE AND 0-1 KM SHEAR
   AROUND 20 KT PER AMA VWP DATA. MODIFIED 00Z AMA RAOB SUGGESTS MLCIN
   IS STILL WEAK AS CONVECTION PROGRESSES INTO AN INCREASINGLY MOIST
   BOUNDARY LAYER GIVEN DOWNSTREAM MIDDLE TO UPPER 60S SURFACE DEW
   POINTS AND 00Z MAF RAOB. THIS SUGGESTS THE SEVERE RISK SHOULD
   CONTINUE THROUGH THE REST OF THE EVENING ALONG AND S OF THE I-40
   CORRIDOR.
