   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0343 AM CDT THU JUL 19 2007
   
   VALID 191200Z - 201200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR CNTRL AND ERN NV...WRN UT...
   
   ...SYNOPSIS...
   UPPER SHORTWAVE EMBEDDED WITHIN WRN U.S. TROUGH WILL SWING NEWD
   THROUGH WA/OR/ID WHICH WILL RELAX UPPER HEIGHT GRADIENT ACROSS THE
   GREAT BASIN AND DECREASE WINDS COMPARED TO PREVIOUS DAY. A FRONT
   WILL EXTEND FROM CO EWD INTO THE OH VALLEY WITH RAIN AND STORMS.
   HIGH PRESSURE WILL BUILD SWD THROUGH THE UPPER MS VALLEY BEHIND THE
   FRONT...WITH COOLER AND DRIER CONDITIONS WITH NLY WINDS.
   
   ...CRITICAL FIRE WEATHER AREA - CNTRL AND ERN NV...WRN UT...
   
   PRIMARY CONDITIONS: STRONG GUSTY WINDS...LOW RH...HOT TEMPERATURES
   
   STALLED FRONTAL BOUNDARY WILL WEAKEN THROUGH THE DAY ACROSS ID AND
   NV WHERE IT WILL REMAIN HOT AND DRY. SLY WINDS E OF THIS FRONT WILL
   REMAIN MODERATELY STRONG OVER CNTRL AND ERN NV INTO WRN
   UT...ESPECIALLY IN THE HIGHER TERRAIN WITH SPEEDS AT OR ABOVE 20
   MPH. UPPER SINGLE DIGIT TO LOWER TEEN RH WILL PREVAIL THIS
   AFTERNOON. THE HOT AND DRY CONDITIONS /MDT TO HIGH HAINES/ WILL ONCE
   AGAIN BE FAVORABLE FOR AFTERNOON FIRE GROWTH.
   
   ...MUCH OF UT...
   VERY HOT AND DRY CONDITIONS WILL RESULT IN A HIGH HAINES INDEX WHICH
   WILL FAVOR INTENSIFICATION OF ONGOING FIRES THIS AFTERNOON.
   ALSO...ANY FIRE STARTS CAUSED BY LIGHTNING THE PREVIOUS DAY COULD
   FLARE UP. CNTRL AND ERN UT WILL REMAIN E OF THE STRONGEST WIND
   POTENTIAL BUT LOCALLY STRONG GUSTS MAY OCCUR. ADDITIONAL ISOLATED
   LIGHTNING STRIKES ARE LIKELY OVER THE HIGHER TERRAIN OF ERN UT.
   
   ...SRN CA...
   VERY HOT CONDITIONS WILL PREVAIL OVER THE SERN CA DESERTS WITH
   SINGLE DIGIT RH. GIVEN THE STRONG HEATING...SWLY WINDS WILL DEVELOP
   FROM THE ANTELOPE VALLEY TOWARD THE MOJAVE DESERT. SUSTAINED SPEEDS
   MAY REACH 20 MPH WITH HIGHER GUSTS LIKELY.
   
   ...SERN ID/SWRN MT...
   LOCALLY GUSTY WINDS WILL DEVELOP TODAY BUT SUSTAINED SPEEDS SHOULD
   REMAIN BELOW 15-20 MPH IN GENERAL AS UPPER FLOW WEAKENS. IT WILL BE
   HOT AND DRY WITH MIN RH NEAR 15 PERCENT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0415 AM CDT THU JUL 19 2007
   
   VALID 201200Z - 211200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR MUCH OF CNTRL AND ERN NV...WRN
   UT...SRN AND ERN ID...SWRN MT...
   
   ...SYNOPSIS...
   UPPER RIDGE WILL BUILD FURTHER ACROSS THE WRN STATES WITH CONTINUED
   VERY HOT AND DRY CONDITIONS. THE HOT AND UNSTABLE AIR WILL SPREAD
   BACK NWWD ACROSS ID/NV INTO ERN OREGON WITH CRITICAL COMBINATIONS
   FROM NV INTO SW MT. MEANWHILE...ERN U.S. TROUGH WILL AMPLIFY FURTHER
   AND WILL HELP TO PUSH SURFACE HIGH PRESSURE SWD INTO THE GREAT LAKES
   AND MIDWEST.
   
   ...CRITICAL FIRE WEATHER AREA - MUCH OF CNTRL AND ERN NV...WRN
   UT...SRN AND ERN ID...SWRN MT...
   
   PRIMARY CONDITIONS: STRONG AND GUSTY WINDS...VERY HOT AND DRY
   CONDITIONS...MDT TO HIGH HAINES
   
   VERY HOT AND DRY CONDITIONS WILL CONTINUE WITH UPPER RIDGE BUILDING
   OVERHEAD. GUSTY SWLY WINDS WILL OCCUR OVER A LARGE AREA FROM SRN NV
   INTO SWRN MT...WITH SUSTAINED SPEEDS NEAR 20 MPH. MIN RH WILL
   AVERAGE FROM THE SINGLE DIGITS NV TO NEAR 15 PERCENT INTO SWRN MT.
   VERY UNSTABLE CONDITIONS WILL DEVELOP BY AFTERNOON WITH A HIGH
   HAINES INDEX OVER MUCH OF THE AREA.
   
   ...ERN OREGON...WRN ID...NWRN NV...
   SWLY WINDS OF 15-20 MPH ARE EXPECTED ACROSS NWRN NV...ERN OREGON
   INTO WRN ID AS AN EMBEDDED DISTURBANCE LIFTS NEWD AND RIDGE BUILDS.
   GIVEN RH NEAR 10 PERCENT...STRONGER THAN EXPECTED WINDS WOULD LEAD
   TO CRITICAL OUTLOOK FOR THIS AREA AS WELL. VERY HOT AND DRY
   CONDITIONS MAY REVEAL ADDITIONAL FIRES STARTED BY RECENT LIGHTNING.
   
   ...SRN CA...
   VERY HOT AND DRY CONDITIONS ALONG WITH GUSTY AFTERNOON WINDS WILL
   PERSIST OVER THE ANTELOPE VALLEY AND MOJAVE DESERT DUE TO
   DIFFERENTIAL HEATING ACROSS THE TERRAIN.
