   MESOSCALE DISCUSSION 0278
   NWS STORM PREDICTION CENTER NORMAN OK
   0305 PM CDT FRI APR 10 2015

   AREAS AFFECTED...SWRN TX

   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 

   VALID 102005Z - 102200Z

   PROBABILITY OF WATCH ISSUANCE...40 PERCENT

   SUMMARY...CONTINUED INCREASE IN THUNDERSTORM ACTIVITY IS EXPECTED IN
   SWRN TX THROUGH THE AFTERNOON.  TRENDS ARE BEING MONITORED FOR A
   POSSIBLE WW.

   DISCUSSION...ISOLATED THUNDERSTORMS HAVE DEVELOPED ALONG THE HIGHER
   TERRAIN OF SWRN TEXAS IN VICINITY OF MRF. ALTHOUGH STORMS ARE
   FORMING IN AN ENVIRONMENT OF MODEST MID-LEVEL FLOW...LOW-LEVEL SELY
   FLOW IS CONTRIBUTING TO DEEP LAYER SHEAR APPROACHING 40-45
   KNOTS...SUPPORTING STORM ORGANIZATION.  CURRENT STORMS ARE
   STRUGGLING TO REMAIN ORGANIZED ATTM...BUT GRADUALLY INCREASING
   INSTABILITY DUE TO SOLAR HEATING AND CONTINUED ADVECTION OF
   WARM/MOIST BOUNDARY LAYER AIR WILL CONTRIBUTE TO INCREASING
   THUNDERSTORM ACTIVITY THROUGHOUT THE AFTERNOON HOURS.  HAIL IS THE
   PRIMARY THREAT WITH THE STRONGEST STORMS...ALTHOUGH A BRIEF TORNADO
   CANNOT BE RULED OUT GIVEN SUBSTANTIAL VEERING OF WIND WITH HEIGHT
   NOTED ON MODEL FORECAST SOUNDINGS.  TRENDS WILL BE MONITORED FOR
   POSSIBLE WW ISSUANCE LATER THIS AFTERNOON.
