   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0248 AM CDT WED AUG 16 2006
   
   VALID 161200Z - 171200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR MOST OF OR/MOST OF NV/SRN ID/EXTRM
   NE CA/NW UT...
   
   ...SYNOPSIS...
   A LARGE SCALE UPPER LEVEL STORM SYSTEM WILL MOVE INTO THE
   NORTHWESTERN PART OF THE UNITED STATES...BRINGING A COLD FRONT
   THROUGH THE REGION. AHEAD OF THIS FRONT...TEMPERATURES WILL BE WARM
   WITH LOW RELATIVE HUMIDITY VALUES...AND SOME AREAS WILL EXPERIENCE
   GUSTY WINDS. IN ADDITION...MID-LEVEL MOISTURE ASSOCIATED WITH THE
   STORM SYSTEM WILL PROVIDE SOME AREAS...ESPECIALLY OREGON AND
   IDAHO...WITH THE POTENTIAL FOR DRY THUNDERSTORM ACTIVITY GIVEN THE
   LACK OF LOW-LEVEL MOISTURE IN THE REGION. ELSEWHERE...A
   CLIMATOLOGICALLY STANDARD HIGH PRESSURE SYSTEM WILL DOMINATE THE
   EASTERN TWO-THIRDS OF THE UNITED STATES...WITH NO OTHER LARGE-SCALE
   FIRE WEATHER THREATS.
   
   ...CRITICAL FIRE WEATHER AREA - MOST OF OR/MOST OF NV/SRN ID/EXTRM
   NE CA/NW UT...
   
   PRIMARY CONDITIONS: AREAS OF DRY THUNDERSTORMS COUPLED WITH LOW
   RH...WARM SFC TEMPS...AND GUSTY WINDS
   
   DRY THUNDERSTORMS ARE LIKELY IN THE NORTHERN PORTION OF THE CRITICAL
   RISK AREA AS A UPPER-LEVEL STORM SYSTEM MOVES INTO THE REGION DURING
   THE FORECAST PERIOD. THE LOWER PORTIONS OF THE ATMOSPHERE HERE WILL
   BE VERY DRY...BUT MID-LEVEL MOISTURE AND THE ASSOCIATED LIFT WITH
   THE STORM WILL HELP FUEL SOME THUNDERSTORMS IN THE AREA. DRY
   LIGHTNING IS POSSIBLE WITH THESE STORMS AND COULD AID IN IGNITING
   FIRES AS SURFACE FUELS ARE VERY DRY IN THE REGION...IN
   ADDITION...STRONG AND GUSTY WINDS ARE POSSIBLE WITH COLLAPSING
   THUNDERSTORMS WHICH COULD RESULT IN ERRATIC FIRE BEHAVIOR. FURTHER
   SOUTH IN THE RISK AREA...A COLD FRONT WILL MOVE THROUGH...AND HOT
   SURFACE TEMPERATURES COMBINED WITH VERY LOW RELATIVE HUMIDITY VALUES
   IN THE SINGLE DIGITS TO UPPER TEENS...COUPLED WITH GUSTY SURFACE
   WINDS AROUND 20 TO 25 KTS SUSTAINED...WILL CREATE A DANGEROUS FIRE
   WEATHER THREAT IN THE AREA...ESPECIALLY DURING THE AFTERNOON AND
   EARLY EVENING HOURS WHEN SURFACE HEATING IS AT A MAXIMUM.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0357 AM CDT WED AUG 16 2006
   
   VALID 171200Z - 181200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A STORM SYSTEM WILL CONTINUE TO MOVE INTO THE NORTHWESTERN UNITED
   STATES...WITH A SURFACE LOW PRESSURE SYSTEM LOCATED IN WESTERN IDAHO
   AT THE BEGINNING OF THE PERIOD. A COLD FRONT ASSOCIATED WITH THIS
   SYSTEM WILL EXTEND SOUTHWARD INTO SRN IDAHO THROUGH CENTRAL
   NEVADA...AND WILL MOVE SOUTHEASTWARD DURING THE PERIOD...WHILE THE
   LOW PRESSURE SYSTEM WILL MOVE EASTWARD INTO CNTRL WYOMING. WINDS
   AHEAD OF THIS SURFACE LOW WILL BE FAIRLY GUSTY...ESPECIALLY DURING
   THE AFTERNOON HOURS...BUT MODERATE SURFACE TEMPERATURES AND RELATIVE
   HUMIDITY VALUES WILL LOWER THE FIRE WEATHER THREAT. IN OTHER
   PORTIONS OF THE COUNTRY...PRECIPITATION AND THUNDERSTORMS ARE
   EXPECTED OVER THE MIDWEST AND PLAINS...WITH SEASONAL CONDITIONS IN
   THE EASTERN US.
   
   ...SRN WY/NRN UT...
   SURFACE WINDS AROUND AND AHEAD OF THE LOW PRESSURE SYSTEM THAT WILL
   MOVE FROM WESTERN IDAHO INTO CENTRAL WYOMING WILL BE FAIRLY STRONG
   AND GUSTY...WITH 20 TO 30 KTS POSSIBLE...BUT SURFACE TEMPERATURES IN
   THE 80S F AND RELATIVE HUMIDITY VALUES MAINLY IN THE TWENTY PERCENT
   RANGE WILL HELP TO KEEP THE FIRE WEATHER THREAT AT A MINIMUM. SOME
   AREAS COULD SEE RELATIVE HUMIDITY VALUES DIP INTO THE TEENS DURING
   THE LATE AFTERNOON AND EVENING HOURS...AND COUPLED WITH DRY SURFACE
   FUELS IN THE REGION...A MINIMAL FIRE THREAT DOES EXIST...BUT DOES
   NOT WARRANT A CRITICAL RISK AT THIS TIME.
