   MESOSCALE DISCUSSION 0562
   NWS STORM PREDICTION CENTER NORMAN OK
   0941 AM CDT SAT MAY 09 2015

   AREAS AFFECTED...NORTH TX/SOUTHEAST OK TO WESTERN AR/NORTHWEST LA

   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 

   VALID 091441Z - 091645Z

   PROBABILITY OF WATCH ISSUANCE...60 PERCENT

   SUMMARY...SEVERE POTENTIAL IS EXPECTED TO GRADUALLY INCREASE BY
   AFTERNOON WITH AN INCREASING RISK FOR DAMAGING WINDS/SEVERE HAIL AND
   POTENTIALLY SOME TORNADO RISK FROM PARTS OF NORTH TX/SOUTHEAST OK
   TOWARD WESTERN AR/NORTHWEST LA.

   DISCUSSION...MULTIPLE STORM CLUSTERS PERSIST EAST-NORTHEASTWARD
   ACROSS NORTH-CENTRAL TX/SOUTH-CENTRAL OK AT MID-MORNING...WITH THE
   STRONGEST CLUSTER ONGOING JUST NORTH-NORTHWEST OF THE DFW METROPLEX.
   RELATIVELY THICK CLOUD COVER STILL PERSISTS TO THE EAST...BUT SOME
   CLOUD BREAKS AND A VERY MOIST AIR MASS...PARTICULARLY NEAR/SOUTH OF
   A WEST-EAST ARCING OUTFLOW BOUNDARY ACROSS NORTHEAST TX...SHOULD
   ALLOW FOR ADDITIONAL STORM DEVELOPMENT/INTENSIFICATION AS THE
   BOUNDARY LAYER HEATS. WHILE DEEP-LAYER SHEAR APPEARS TO WEAKEN WITH
   EASTWARD EXTENT...MOIST EASTERLY LOWER-LEVEL INFLOW WILL SUPPORT
   RELATIVELY ORGANIZED STORM MODES POTENTIALLY INCLUDING BOWING
   CLUSTERS WITH SOME EMBEDDED SUPERCELLS.
