   ...MI/OH...
   BROAD UPPER TROUGH WILL REMAIN OVER MUCH OF THE CENTRAL UNITED
   STATES ON FRIDAY...WITH A STRONG SHORTWAVE TROUGH ROTATING EASTWARD
   ACROSS THE MS VALLEY.  MID LEVEL LAPSE RATES AND RESULTANT
   INSTABILITY WILL BE MUCH LESS ON DAY2 THAN PREVIOUS DAYS WITH MLCAPE
   VALUES OF 1000 J/KG OR LESS FROM LOWER MI INTO EASTERN TX. 
   RELATIVELY STRONG WIND FIELDS MAY ALLOW ISOLATED STRONG STORMS TO
   PRODUCE GUSTY/DAMAGING WINDS OVER PARTS OF LOWER MI AND NORTHERN OH
   ON FRIDAY...BUT NO ORGANIZED SEVERE STORMS ARE EXPECTED.
   
   ...SOUTH TX...
   ONE AREA WHERE STRONG INSTABILITY WILL PERSIST ON FRIDAY WILL BE
   OVER SOUTH TX...WHERE VERY WARM/MOIST SURFACE CONDITIONS WILL RESULT
   IN MLCAPE VALUES OVER 3000 J/KG.  SCATTERED THUNDERSTORMS WILL
   LIKELY BE ONGOING ALONG FRONT OVER CENTRAL TX AT THE BEGINNING OF
   THE PERIOD...WITH ACTIVITY SPREADING SOUTHWARD INTO SOUTH TX DURING
   THE AFTERNOON. LOW/MID LEVEL WINDS WILL BE RATHER WEAK...SUGGESTING
   SIGNIFICANT CONVECTIVE ORGANIZATION IS UNLIKELY.  HOWEVER...HOT
   SURFACE TEMPS AND DEGREE OF INSTABILITY COULD POSE A RISK OF
   DAMAGING WINDS IN A FEW CELLS. THIS AREA WILL BE MONITORED IN LATER
   OUTLOOKS FOR POSSIBLE UPGRADE TO SLIGHT RISK IF VERTICAL SHEAR IS
   SLIGHTLY STRONGER THAN CURRENTLY FORECAST.
