   ...WRN U.S...
   
   DIFFLUENT UPPER FLOW WILL CONTINUE ACROSS THE NWRN U.S. TODAY AS
   SPEED MAX APPROACHES THE CENTRAL CA COAST LATE IN THE PERIOD. 
   PERSISTENT LARGE SCALE ASCENT ALONG BAROCLINIC ZONE FROM CENTRAL
   CA...NEWD INTO WRN MT WILL SERVE TO MOISTEN/SATURATE PORTIONS OF
   MID-UPPER LEVELS ALONG THIS ZONE.  IT APPEARS ISOLATED
   THUNDERSTORMS SHOULD DEVELOP ACROSS THIS REGION...ESPECIALLY AS
   DAYTIME HEATING ENHANCES MARGINALLY UNSTABLE SOUNDINGS.  ALTHOUGH
   THUNDERSTORMS MAY BE CONCENTRATED OVER HIGHER TERRAIN DURING THE
   AFTERNOON/EVENING HOURS...APPROACHING COLD FRONT WILL MAINTAIN
   CONVECTIVE THREAT ALONG THE CALIFORNIA COAST DURING THE OVERNIGHT
   HOURS.
   
   ...CENTRAL TX...
   
   UPPER RIDGE WILL GRADUALLY SHIFT ACROSS WRN INTO CNTRL TX DURING
   THE PERIOD.  OTHERWISE BENIGN LARGE SCALE PATTERN MAY ACTUALLY
   SUPPORT ISOLATED THUNDERSTORM DEVELOPMENT BY LATE AFTERNOON OVER
   PORTIONS OF TX...PARTIALLY DUE TO WEAK WARM ADVECTION BUT MORE
   LIKELY DUE TO STRONG DIURNAL HEATING.  LATEST FORECAST SOUNDINGS
   SUGGEST INHIBITION WILL BE INSIGNIFICANT AS SFC TEMPERATURES WARM
   INTO THE LOWER 80S WITH DEW POINTS RISING INTO THE LOWER-MID
   50S...YIELDING CAPE VALUES ON THE ORDER OF 1000 J/KG.  LACK OF
   SIGNIFICANT LOW LEVEL FORCING DOES NOT PROVIDE GREAT CONFIDENCE IN
   REGION OF INITIATION BUT STRONG DIURNAL HEATING MAY ULTIMATELY
   RESULT IN ISOLATED THUNDERSTORMS WHICH SHOULD DISSIPATE WITH LOSS
   OF DAYTIME HEATING.
