   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0327 AM CDT THU JUN 25 2009
   
   VALID 251200Z - 261200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   PERSISTENT UPPER-LEVEL ANTICYCLONE WILL REMAIN ANCHORED ACROSS THE
   SRN PLAINS. AN UPPER-LEVEL LOW OFF THE SRN CA COAST WILL GRADUALLY
   ACCELERATE 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 INCREASING MID-LEVEL MOISTURE WILL
   CONTRIBUTE TO A SUBSTANTIAL INCREASE IN AREAL EXTENT OF TSTM
   COVERAGE ACROSS THE WEST.
   
   ...CNTRL CA TO ERN MT...
   ISOLATED TO SCATTERED TSTMS SHOULD DEVELOP THIS AFTERNOON INTO THE
   EVENING FROM THE SIERRAS NEWD TO THE NRN ROCKIES. SOME OF THESE
   TSTMS WILL BE DRY AT LOWER ELEVATIONS WHERE SURFACE TEMPERATURE/DEW
   POINT SPREADS AOA 50 DEG F WILL BE COMMON. HOWEVER...WITH RECENT
   ABOVE-NORMAL RAINFALL OVER MOST OF THE GREAT BASIN/NRN ROCKIES AND
   GACC FORECASTS MAINTAINING MOIST/GREEN FUELS...OVERALL IGNITION
   POTENTIAL DOES NOT APPEAR SUPPORTIVE OF ANY CRITICAL AREAS FROM THE
   SIERRA CREST NEWD. WHERE CURED FUELS AND DRY TSTM POTENTIAL APPEAR
   TO CO-EXIST ALONG THE WRN SIERRA FOOTHILLS...MODEL FORECAST
   SOUNDINGS SUGGEST MLCIN MAY REMAIN LARGE ENOUGH TO INHIBIT TSTM
   DEVELOPMENT WITHIN THIS CORRIDOR...AS RICHER SUB-TROPICAL MOISTURE
   IS SHUNTED ALONG AND E OF THE SIERRAS.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0331 AM CDT THU JUN 25 2009
   
   VALID 261200Z - 271200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER-LEVEL ANTICYCLONE WILL REMAIN ENTRENCHED ACROSS THE SRN
   PLAINS. AN UPPER-LEVEL SHORT WAVE TROUGH ACROSS THE SRN CANADIAN
   ROCKIES WILL EVOLVE EWD ACROSS THE SRN PRAIRIE PROVINCES AND FAR NRN
   HIGH PLAINS. SRN STREAM SHORT WAVE TROUGH OVER THE SIERRAS SHOULD
   WEAKEN AS IT CROSSES THE GREAT BASIN...WITH IMPULSES EJECTING
   DOWNSTREAM INTO THE NRN PLAINS.
   
   ...W-CNTRL/SWRN KS...
   LEE TROUGH WILL DEEPEN AS MID-LEVEL HEIGHT FALLS OVERSPREAD THE
   NRN/CNTRL HIGH PLAINS. SLY LOW-LEVEL WINDS WILL STRENGTHEN ACROSS
   MOST OF WRN KS WITH SUSTAINED SURFACE SPEEDS APPROACHING 25 MPH FRI
   AFTERNOON. WITH TEMPERATURES WARMING TO NEAR 100 DEG F...RH VALUES
   SHOULD BECOME MARGINALLY LOW /AROUND 20 PERCENT/.
   NEVERTHELESS...LATEST GACC FORECAST OF MOIST/GREEN FUELS SUGGESTS
   OVERALL FIRE POTENTIAL SHOULD REMAIN LOW.
