   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0308 AM CDT THU JUL 03 2008
   
   VALID 031200Z - 041200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A STRONG UPPER RIDGE AXIS WILL EXTEND FROM WRN MT/NRN ID SWD INTO
   THE GREAT BASIN WITH THE THERMAL RIDGE AXIS FROM ERN WA/OR INTO NV.
   VERY WARM AND DRY WEATHER WILL PERSIST OVER MUCH OF THE AREA AS A
   RESULT. THE WRN EDGE OF THE RIDGE WILL BEGIN TO BREAK DOWN SLIGHTLY
   AS AN UPPER TROUGH SHIFTS EWD ALONG THE PACIFIC COAST. THUNDERSTORMS
   WITH RAIN WILL OCCUR OVER MUCH OF WA...WITH MORE SCATTERED ACTIVITY
   OVER OREGON. ISOLATED DRY STORMS ARE LIKELY FROM ERN OREGON INTO
   CNTRL ID.
   
   TO THE E...HIGH PRESSURE WILL BUILD ACROSS THE UPPER MS VALLEY AND
   GREAT LAKES REGION BEHIND A COLD FRONT THAT WILL STRETCH FROM NEW
   ENGLAND SWWD INTO MO THIS AFTERNOON. ALONG THE FRONT...NUMEROUS
   STORMS WILL OCCUR..BUT WELL AHEAD OF THE FRONT INTO THE MID ATLANTIC
   STATES IT WILL BE VERY WARM AND DRY WITHIN A WEAK SURFACE TROUGH.
   
   ...ERN OREGON...CNTRL ID...
   IT WILL BECOME VERY HOT AND DRY WITHIN THE THERMAL RIDGE AXIS THIS
   AFTERNOON...WITH HIGH TEMPERATURES REACHING 100 F ACROSS LOWER
   ELEVATIONS ALONG WITH MIN RH IN THE LOWER TEENS. A COLD FRONT WILL
   BE SITUATED ACROSS ERN WA INTO CNTRL OREGON...AND THIS WILL BE A
   FOCUS FOR THUNDERSTORM DEVELOPMENT LATE IN THE DAY. OVERALL MOISTURE
   CONTENT NEAR THE FRONT WILL SUPPORT SCATTERED THUNDERSTORMS WITH
   RAIN. THE HIGHEST PROBABILITY OF DRY THUNDERSTORMS WILL BE OVER ERN
   OREGON INTO ID...WHERE SUB CLOUD LAYERS WILL BE DRIEST. WHILE A FEW
   STORMS COULD PRODUCE LIGHTNING THAT WILL HAVE THE POTENTIAL FOR NEW
   FIRE STARTS...COVERAGE OF THE DRY THUNDERSTORMS IS NOT EXPECTED TO
   BE SIGNIFICANT ENOUGH FOR A CRITICAL AREA.
   
   ...GREAT BASIN...
   WINDS WILL BEGIN TO INCREASE IN RESPONSE TO THE APPROACHING UPPER
   TROUGH. SUSTAINED SWLY WINDS OF 15-20 MPH ARE LIKELY OVER MUCH OF
   NV...WHILE TEMPERATURES REMAIN HOT AND RH VERY LOW. A FEW HIGHER
   GUSTS WILL BE POSSIBLE BUT OVERALL WINDS SHOULD REMAIN BELOW
   CRITICAL LEVELS. A HIGH HAINES INDEX WILL BE IN PLACE AS WELL DUE TO
   THE VERY DRY AND UNSTABLE CONDITIONS...FURTHER ELEVATING FIRE GROWTH
   POTENTIAL.
   
   ...VA/CAROLINAS/GA...
   A WEAK PRE-FRONTAL SURFACE TROUGH WILL FORM LATER TODAY NEAR THE
   PIEDMONT...WITH WARM TEMPERATURES IN THE 90S AND MIN RH VALUES
   MAINLY IN THE 20 PERCENT RANGE. SUSTAINED SWLY WINDS WILL AVERAGE
   NEAR 10 MPH ACROSS THE CAROLINAS...WITH SPEEDS AROUND 15 MPH AND
   GUSTY OVER VA. ALTHOUGH WINDS WILL BE MARGINAL FOR A CRITICAL FIRE
   THREAT...DROUGHT CONDITIONS PERSIST WHICH WILL RESULT IN A MARGINAL
   THREAT THIS AFTERNOON.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0350 AM CDT THU JUL 03 2008
   
   VALID 041200Z - 051200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR CNTRL AND ERN NV...WRN
   UT...EXTREME SERN ID...
   
   ...SYNOPSIS...
   A FAST MOVING UPPER SHORTWAVE TROUGH WILL BREAK DOWN THE NWRN PART
   OF THE UPPER RIDGE...BRINGING STRONG WINDS TO THE GREAT BASIN AND
   NRN ROCKIES...ALONG WITH BOTH WET AND DRY THUNDERSTORMS ALONG A COLD
   FRONT FROM ID INTO WRN MT. MORE ISOLATED DRY STORMS MAY ALSO OCCUR
   FARTHER S OVER WRN WY AND ERN UT. MEANWHILE...A FRONT WILL MOVE
   LITTLE ACROSS THE APPALACHIANS INTO THE LOWER MS VALLEY WITH
   NUMEROUS THUNDERSTORMS. BEHIND THIS FRONT...HIGH PRESSURE WILL KEEP
   CONDITIONS RELATIVELY COOL ACROSS MIDWEST.
   
   ...CRITICAL FIRE WEATHER AREA - CNTRL AND ERN NV...WRN UT...EXTREME
   SERN ID...
   
   PRIMARY CONDITIONS: STRONG WINDS...LOW RH...STRONG LOWER ATMOSPHERIC
   INSTABILITY
   
   AN UPPER SHORTWAVE TROUGH WILL EJECT NNEWD ACROSS THE WRN GREAT
   BASIN AND INTO THE PACIFIC NW ON FRIDAY...AND WILL BRING INCREASED
   WINDS TO THE AREA. SUSTAINED SWLY WINDS SHOULD INCREASE TO 20-30 MPH
   WITH HIGHER GUSTS ALONG AND E OF A COLD FRONT. RH WILL BE IN THE
   SINGLE DIGITS TO LOWER TEENS...AND THE STEEP LOW LEVEL LAPSE RATES
   WILL RESULT IN STRONG LOW LEVEL INSTABILITY AND TURBULENCE. THE COLD
   FRONT WILL ADVANCE SLOWLY SEWD LATE IN THE DAY AND OVERNIGHT...WITH
   WINDS SHIFTING TO NWLY AT AROUND 15 MPH.
   
   ACROSS ERN PORTIONS OF THE CRITICAL INTO UT...ISOLATED DRY
   THUNDERSTORMS ARE EXPECTED LATE IN THE DAY...MAINLY OVER THE HIGH
   TERRAIN. GIVEN VERY WARM AND DRY CONDITIONS...ANY LIGHTNING STRIKE
   WILL HAVE A RELATIVELY HIGH IGNITION EFFICIENCY.
   
   ...ERN ID...SWRN MT...
   AN UPPER SHORTWAVE TROUGH AND A SURFACE COLD FRONT WILL RESULT IN
   NUMEROUS THUNDERSTORMS MAINLY OVER WRN MT AND NRN ID FRI AFTERNOON.
   MEANWHILE...A SURFACE THERMAL TROUGH WILL EXTEND SWD ACROSS SERN ID
   INTO NERN NV/WRN UT. STRONG MIXING AND WIND GUSTS WILL OCCUR IN THIS
   ZONE...WITH SUSTAINED SWLY WINDS NEAR 20 MPH INTO ERN ID AND SWRN
   MT. MIN RH WILL BE MAINLY IN THE TEENS IN THIS SURFACE TROUGH.
   
   MOST THUNDERSTORMS OVER NRN ID AND WRN MT WILL BE WET IN
   NATURE...WITH HEAVY RAIN...HAIL...AND STRONG WINDS LIKELY.
   HOWEVER...THE STORMS WILL BECOME DRIER WITH SWD EXTEND...AND A
   FAVORABLE AREA FOR DRY THUNDERSTORMS MAY DEVELOP...FROM SWRN MT INTO
   SERN ID. COORDINATION WITH LOCAL AGENCIES REVEALS THAT OVERALL FUEL
   CONDITIONS ARE NOT FAVORABLE FOR AN OUTBREAK OF FIRES.
