   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   1257 AM CDT SUN AUG 10 2008
   
   VALID 101200Z - 111200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   THE UPPER LOW BEGINNING TO MOVE INTO SWRN BRITISH COLUMBIA WILL
   SLOWLY PROGRESS NEWD TODAY. HOT AND DRY CONDITIONS WILL CONTINUE
   ACROSS MUCH OF THE WRN STATES AS UPPER RIDGING SLOWLY BUILDS IN
   BEHIND. GIVEN TRAJECTORY OF THE UPPER LOW...THE STRONGEST WINDS WILL
   REMAIN CLOSE TO THE U.S./CANADIAN BORDER...WHERE ABOVE NORMAL
   MOISTURE AND MARGINAL RELATIVE HUMIDITIES WILL EXIST. FARTHER
   W...RELATIVE HUMIDITIES WILL DROP INTO THE TEENS...ALTHOUGH
   SUSTAINED WINDS WILL REMAIN BELOW CRITICAL THRESHOLDS.
   HOWEVER...LOCALLY GUSTY WINDS MAY BE POSSIBLE ACROSS PORTIONS OF ERN
   ID/NRN UT/SWRN MT AND FAR WRN WY IN A POST COLD FRONTAL REGIME.
   MEANWHILE AT THE SURFACE...THE COLD FRONTAL PROGRESSION WILL BE
   SOMEWHAT SLOW...ALTHOUGH A WIND SHIFT WILL OCCUR IN WRN MT/WY...WITH
   GUSTY WINDS FOLLOWING THE FRONTAL PASSAGE.  
     
   IN THE FOUR CORNERS REGION AND ERN GREAT BASIN...WET THUNDERSTORMS
   WILL CONTINUE TO AFFECT A WIDESPREAD AREA IN THE AFTERNOON.
   HOWEVER...PORTIONS OF SRN CA/NV...SWRN UT...AND FAR WRN AZ WILL
   EXPERIENCE DRIER CONDITIONS IN COMPARISON TO RECENT DAILY ACTIVITY.
   
   ...ERN ID/NRN UT/SWRN MT/FAR WRN WY...
   WV IMAGERY/GPS PWAT DATA REFLECT MUCH DRIER AIR MOVING NEWD AHEAD OF
   THE UPPER TROUGH AND FOLLOWING THE SURFACE COLD FRONTAL PASSAGE. 00Z
   UPSTREAM SOUNDING DATA AT REV/LKN/BOI REFLECT THIS TREND WITH
   APPROXIMATELY .40 DROP IN PWAT COMPARED TO 12Z YESTERDAY. DESPITE
   COOLER TEMPERATURES FOLLOWING THE FRONTAL PASSAGE...RELATIVE
   HUMIDITIES...ALREADY IN THE TEENS ACROSS MANY LOWER VALLEYS AT 06Z
   THIS MORNING...WILL REMAIN LOW IN THE AFTERNOON. SUSTAINED WINDS MAY
   APPROACH 20 MPH...AND MIXING AT PEAK HEATING WILL ALLOW STRONGER
   GUSTS TO REACH THE SURFACE. HOWEVER...RECENT RAINFALL WILL TEND TO
   HINDER OVERALL FIRE THREAT. FURTHERMORE...INTO NERN UT/WRN WY/WRN
   MT...SOME DEGREE OF MOISTURE/INSTABILITY MAY BE SUPPORTIVE OF A FEW
   THUNDERSTORMS...INITIALLY WET...BUT DRYING WILL GRADUALLY CONTINUE
   THROUGH THE AFTERNOON.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0138 AM CDT SUN AUG 10 2008
   
   VALID 111200Z - 121200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   IN THE WEST...THE UPPER LOW NOW MOVING INTO SWRN BRITISH COLUMBIA
   WILL SLOWLY PROGRESS EWD ACROSS ALBERTA INTO SASKATCHEWAN. STRONGER
   WINDS IN ASSOCIATION WITH THIS SYSTEM WILL MAINLY BE CONFINED CLOSER
   TO THE U.S./CANADIAN BORDER...WHERE RELATIVE HUMIDITIES WILL BE
   SOMEWHAT MARGINAL. UPPER RIDGING WILL SLOWLY BUILD OVER THE WEST
   FOLLOWING THIS SYSTEM...WITH HOT AND DRY CONDITIONS OVER A
   WIDESPREAD AREA. IN THE FOUR CORNERS REGION...AREAS WEST WILL
   GRADUALLY TRANSITION INTO A DRIER REGIME...AND AFTERNOON
   THUNDERSTORMS WILL MAINLY BE CONFINED TO SRN AZ NEWD THROUGH THE
   ROCKIES.
   
   MEANWHILE IN THE EAST...AN UPPER/SFC LOW WILL GRADUALLY MOVE
   OFFSHORE...AND DRY CONDITIONS WILL FOLLOW THE FRONTAL PASSAGE ACROSS
   INLAND AREAS IN THE MID ATLANTIC. HOWEVER...RELATIVE HUMIDITIES ARE
   EXPECTED TO STAY ABOVE CRITICAL THRESHOLDS...AND WINDS WILL
   GENERALLY BE LIGHT.
   
   ...PORTIONS OF ID/WRN WY/WRN MT...
   TEMPERATURES WILL BE SOMEWHAT WARMER COMPARED TO THE PREVIOUS
   DAY...AND RELATIVE HUMIDITIES WILL ONCE AGAIN DROP INTO THE TEENS BY
   THE AFTERNOON...MAINLY IN THE LOWER VALLEYS. ALTHOUGH SUSTAINED
   WINDS APPEAR TO BE MARGINAL...GUSTY WINDS NEAR 25 TO 30 MPH MAY BE
   POSSIBLE IN THE AFTERNOON. FIRE THREAT WILL ALSO DEPEND ON HOW MUCH
   DRYING CAN OCCUR ON DY1 GIVEN RECENT RAINFALL...THEREFORE CRITICAL
   AREAS WILL NOT BE OUTLINED AT THIS TIME.
