MESOSCALE DISCUSSION 0786
   NWS STORM PREDICTION CENTER NORMAN OK
   0322 PM CDT TUE MAY 26 2015

   AREAS AFFECTED...N-CNTRL AND NERN OK...FAR SERN KS

   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 

   VALID 262022Z - 262115Z

   PROBABILITY OF WATCH ISSUANCE...20 PERCENT

   SUMMARY...A THREAT FOR ISOLATED LARGE HAIL AND STRONG WIND GUSTS
   WILL EXIST THIS AFTERNOON FROM N-CNTRL/NERN OK INTO SERN KS OVER THE
   NEXT COUPLE HOURS. A WW IS NOT CURRENTLY ANTICIPATED.

   DISCUSSION...ISOLATED TSTMS HAVE DEVELOPED ACROSS N-CNTRL OK AHEAD
   OF A WEAK UPPER IMPULSE MOVING INTO WRN OK...WITH THE STRONGEST
   STORM /AS OF 2015Z/ ENTERING LINCOLN/PAYNE COUNTIES OK WITH A
   HISTORY OF PRODUCING LARGE HAIL. VISIBLE SATELLITE/RADAR TRENDS
   SUGGEST THIS ACTIVITY MAY BE SLIGHTLY ELEVATED...BUT 30 KTS OF
   CLOUD-LAYER SHEAR COMBINED WITH STEEP MIDLEVEL LAPSE RATES /7.5 C
   PER KM/ WILL BE SUFFICIENT FOR AN ISOLATED THREAT FOR LARGE HAIL AND
   STRONG WIND GUSTS. A WW IS NOT CURRENTLY ANTICIPATED AS CINH MAY
   PRECLUDE SFC-BASED TSTM DEVELOPMENT AND COVERAGE SHOULD REMAIN
   ISOLATED.
