   DAY 1 CONVECTIVE OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   1112 AM CDT WED JUL 30 2014

   VALID 301630Z - 311200Z

   ...NO SVR TSTM AREAS FORECAST...

   ...SUMMARY...
   ISOLATED SEVERE STORMS ARE POSSIBLE ACROSS PORTIONS OF OKLAHOMA AND
   NORTH TEXAS THIS AFTERNOON INTO EVENING.

   ...OK/TX...
   WATER VAPOR LOOPS SHOW AN UPPER SHORTWAVE TROUGH TRACKING
   SOUTHEASTWARD ACROSS THE CENTRAL PLAINS.  THIS HAS RESULTED IN
   WIDESPREAD CLOUDS AND PRECIPITATION OVER MUCH OF KS/OK AND PARTS OF
   NORTH TX.  AN OUTFLOW BOUNDARY /EFFECTIVE WARM FRONT/ LIES ALONG THE
   SOUTHERN EDGE OF THE CLOUD SHIELD OVER NORTH TX.  THIS BOUNDARY WILL
   LIKELY BE THE FOCUS FOR SCATTERED THUNDERSTORM DEVELOPMENT THIS
   AFTERNOON AS DAYTIME HEATING OCCURS.  MODEL SOLUTIONS SUGGEST THAT
   STORMS FORM OVER THE EASTERN TX PANHANDLE AND RIDE DOWN THE BOUNDARY
   INTO WESTERN NORTH TX THIS EVENING.  MID LEVEL LAPSE RATES ARE
   WEAK...AND OVERALL THERMODYNAMIC SETUP IS NOT PARTICULARLY FAVORABLE
   FOR SEVERE STORMS.  HOWEVER...VEERING WINDS WITH HEIGHT AND 40-50
   KNOTS OF NORTHWESTERLY UPPER LEVEL WINDS MAY BE ENOUGH FOR AN
   ISOLATED SUPERCELL OR TWO CAPABLE OF HAIL OR GUSTY/DAMAGING WINDS.
