   VALID 082055Z - 082330Z
   
   STORMS WILL INCREASE WITHIN A LOW PRESSURE TROUGH WITH A FEW
   DAMAGING WIND GUSTS AND PERHAPS SOME SMALL HAIL POSSIBLE.
   
   SURFACE ANALYSIS SHOWS LOW PRESSURE TROUGH FROM NEAR SLN TO PYX WITH
   VERY HOT TEMPERATURES WITHIN. MODIFIED FORECAST SOUNDINGS INDICATE
   CIN WILL BE ERASED SOON WITH DEEP MIXING/STEEP LOW LEVEL LAPSE
   RATES. VISIBLE IMAGERY CONFIRMS THIS IS OCCURRING WITH EXPANSION OF
   CU FIELD. CONTINUED HEATING AND PERSISTENT CONVERGENCE ON NOSE OF
   SWLY 25 KT LOW LEVEL JET WILL LIKELY YIELD SCATTERED STORMS. VEERING
   LOW LEVEL FLOW BUT WEAK FLOW ALOFT SUGGESTS MIXED STORM MODE WITH A
   FEW LONGER LIVED CELLS...SOME SEVERE WITH DAMAGING WIND GUSTS AND
   LOW END SVR HAIL.
