   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0237 AM CDT WED JUN 24 2009
   
   VALID 241200Z - 251200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER-LEVEL HIGH WILL CONTINUE TO RETROGRADE WWD INTO THE SRN
   HIGH PLAINS BY EARLY THU. QUASI-STATIONARY UPPER-LEVEL LOW OFF THE
   SRN CA COAST SHOULD BEGIN A GRADUAL EWD ACCELERATION LATE IN THE
   PERIOD...AIDED BY A VIGOROUS NRN STREAM SHORT WAVE TROUGH ENTERING
   WA/BRITISH COLUMBIA.
   
   ...SRN SIERRA MTNS/WRN MOJAVE DESERT/ANTELOPE AND SAN JOAQUIN
   VALLEYS OF CA...
   24/00Z GFS/NAM FORECASTS HAVE BACKED OFF WITH THE AMPLITUDE OF
   MID-LEVEL MOISTENING FROM THE GULF OF CA/SONORA. ALTHOUGH THEY STILL
   REMAIN FARTHER WEST THAN THE ECMWF WITH THE PLACEMENT OF 700 MB DEW
   POINTS AOA 0 DEG C AT 25/12Z. A FEW HIGH-BASED TSTMS MAY FORM OVER
   THE SRN SIERRAS AT PEAK HEATING IN THE LATE AFTERNOON.
   ELSEWHERE...THE POTENTIAL FOR POSITIVE BUOYANCY ATOP A RESIDUAL
   DEEPLY-MIXED SUB-CLOUD LAYER EARLY THU MORNING APPEARS LOWER THAN IN
   PREVIOUS FORECASTS. THUS...NOCTURNAL TSTM ACTIVITY SHOULD REMAIN NIL
   TO VERY ISOLATED.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0401 AM CDT WED JUN 24 2009
   
   VALID 251200Z - 261200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   PERSISTENT UPPER-LEVEL HIGH WILL REMAIN ANCHORED ACROSS THE SRN HIGH
   PLAINS. AN UPPER-LEVEL LOW OFF THE SRN CA COAST WILL SHIFT SLOWLY
   EWD TOWARDS THE SRN SIERRA MOUNTAINS THROUGH EARLY FRI...WHILE A NRN
   STREAM SHORT WAVE TROUGH PROGRESSES ACROSS THE SRN CANADIAN ROCKIES.
   FORCED ASCENT DOWNSTREAM OF THESE WAVES COMBINED WITH POLEWARD
   TRANSPORT OF RICHER SUB-TROPICAL MOISTURE WILL CONTRIBUTE TO A
   SUBSTANTIAL INCREASE IN THE AREAL EXTENT OF TSTM COVERAGE ACROSS THE
   WEST.
   
   ...CENTRAL VALLEY OF CA...
   DESPITE AN INCREASE IN TSTM COVERAGE ACROSS THE WEST...POTENTIAL FOR
   DRY TSTMS WHERE FUELS ARE SUFFICIENTLY CURED SHOULD BE RESTRICTED TO
   ALONG THE CENTRAL VALLEY OF CA. OVERALL TSTM PROBABILITIES APPEAR
   RATHER LOW IN THIS REGION WITH MORE ROBUST MID-LEVEL MOISTURE
   GENERALLY SHUNTED ALONG AND E OF THE SIERRA MOUNTAINS.
   NEVERTHELESS...IF ISOLATED TSTMS DO FORM...SURFACE TEMPERATURE/DEW
   POINT SPREADS AOA 50 DEG F WOULD SUPPORT GUSTY/ERRATIC WINDS AND DRY
   LIGHTNING.
