   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0431 AM CDT FRI JUL 31 2015

   VALID 011200Z - 021200Z

   ...SYNOPSIS...
   AN UPPER-LEVEL RIDGE IS EXPECTED TO SLOWLY SHIFT EASTWARD ON
   SATURDAY TOWARD THE NORTHERN INTERMOUNTAIN WEST WHILE THE
   LARGE-SCALE TROUGH OVER THE EASTERN CONUS REMAINS NEARLY STATIONARY.
   AT THE SURFACE...HOT AND DRY CONDITIONS WILL PERSIST ACROSS MUCH OF
   THE GREAT BASIN AND DEVELOP FARTHER EAST INTO THE NORTHERN ROCKIES
   AND NORTHERN HIGH PLAINS.  WHILE SURFACE WINDS WILL GENERALLY REMAIN
   WEAK ACROSS MUCH OF THE WEST AND LIMIT THE FIRE WEATHER
   THREAT...VERTICAL MIXING OF ENHANCED LOWER-TROPOSPHERIC FLOW OVER
   NORTHERN MONTANA MAY PROMOTE THE DEVELOPMENT OF LOCALIZED ELEVATED
   FIRE WEATHER CONDITIONS.  OTHERWISE...THE POTENTIAL FOR DIURNALLY
   DRIVEN ISOLATED DRY THUNDERSTORMS EXISTS OVER NORTHERN CALIFORNIA
   AND SOUTHWESTERN OREGON.

   ...NORTHERN CALIFORNIA AND SOUTHWESTERN OREGON...
   WITHOUT ANY OBVIOUS LARGE-SCALE FEATURES TO FOCUS THUNDERSTORM
   DEVELOPMENT...LOCAL TERRAIN-INDUCED CIRCULATIONS FROM DIURNAL
   HEATING WILL BE THE PRIMARY SOURCE OF THUNDERSTORM INITIATION ON
   SATURDAY ACROSS THE REGION.  ALTHOUGH PW VALUES WILL BE MARGINAL FOR
   DRY THUNDERSTORMS /BETWEEN 0.75 AND 1 IN/...DEEP WELL-MIXED BOUNDARY
   LAYERS WILL PROMOTE PRECIPITATION EVAPORATION AND LIMIT SURFACE
   RAINFALL...SUPPORTING ISOLATED DRY THUNDERSTORM POTENTIAL.
