   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0237 AM CDT WED AUG 11 2004
   
   VALID 111200Z - 121200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   FLOW PATTERN ACROSS THE CONUS WILL BE CHARACTERIZED BY AN
   UNSEASONABLY STRONG AND COOL 500MB TROUGH ACROSS THE GREAT LAKES AND
   OHIO VALLEY WITH A HIGH AMPLITUDE RIDGE REMAINING IN PLACE FROM THE
   SRN CA DESERTS NWD TO WA. HOT AND DRY CONDITIONS WILL BE WIDESPREAD
   WEST OF THE CONTINENTAL DIVIDE...WITH A STATIONARY FRONT AND
   AFTERNOON SHOWERS/T-STORMS LIKELY FROM THE CO FRONT RANGE SWD INTO
   NM. BETWEEN WRN RIDGE AND GREAT LAKES TROUGH...ENHANCED 700MB
   BAROCLINIC ZONE WILL EXIST NEAR THE DIVIDE FROM SWRN MT SEWD THROUGH
   CO. MODERATE MID-LEVEL NWLY SYNOPTIC FLOW REGIME ACROSS THE CENTRAL
   ROCKIES REGION WILL PROVIDE A FOCUS FOR DRY AND BREEZY AFTERNOON
   CONDITIONS AND LOCALIZED FIRE WEATHER CONCERNS.
   
   ...SWRN WY/WRN CO/FAR NERN UT...
   
   ETA MODEL SOUNDINGS SUPPORT NWLY 15-20 MPH WINDS ACROSS THE AREA
   DURING THE PEAK AFTERNOON HEATING HOURS AS STEEP LOW-LEVEL LAPSE
   RATES ENHANCE VERTICAL MIXING AND MOMENTUM TRANSFER FROM ALOFT.
   ANTICIPATED WINDS COMBINED WITH RH MINIMUMS BETWEEN 10-15 PERCENT
   MAY POSE A FIRE WEATHER HAZARD FOR A FEW HOURS UNTIL BOUNDARY LAYER
   STABILIZES AFTER SUNSET. FIRE DANGER CLASS RATINGS WERE IN THE VERY
   HIGH TO EXTREME CATEGORY ACROSS MOST OF THE DISCUSSION AREA TUESDAY.
    HOWEVER...WINDS SHOULD REMAIN SLIGHTLY BELOW CRITICAL LEVELS IN
   MOST SECTIONS THIS FORECAST PERIOD...PRECLUDING A CRITICAL FIRE
   WEATHER RISK AREA.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0236 AM CDT WED AUG 11 2004
   
   VALID 121200Z - 131200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   LITTLE OVERALL CHANGE IS EXPECTED IN LARGE-SCALE UPPER FLOW PATTERN
   ON THURSDAY. A SHORTWAVE TROUGH MOVING SEWD ACROSS THE MO RIVER
   VALLEY AT 12/12Z WILL REINFORCE MEAN TROUGH EXTENDING FROM THE
   CENTRAL GREAT LAKES SSWWD INTO THE LOWER MS RIVER VALLEY. A STRONG
   UPPER RIDGE WILL PERSIST FROM AZ NNWWD TO ERN WA. PATTERN REMAINS
   UNUSUALLY AMPLIFIED FOR AUGUST.  
   
   IN ASSOCIATION WITH THE WRN RIDGE...HOT TEMPERATURES WILL PREVAIL
   ACROSS MOST OF THE INTERMOUNTAIN REGION. AFTERNOON RH VALUES BELOW
   15 PERCENT ARE LIKELY ACROSS THE GREAT BASIN...INTERIOR VALLEYS OF
   CA NWD INTO THE COLUMBIA BASIN...THE SNAKE RIVER PLAIN...AND MUCH OF
   THE FOUR CORNERS REGION. LIGHT WINDS...DRIVEN PRIMARILY BY LOCAL
   TOPOGRAPHIC EFFECTS...WILL MITIGATE LARGE-SCALE FIRE WEATHER IMPACT.
   HOWEVER...PRESENCE OF STEEP LAPSE RATES AND LOW TO VERY LOW RH
   VALUES WILL CONTRIBUTE TO PLUME DOMINANT FIRE POTENTIAL IN HEAVIER
   FUEL LOADINGS. 
   
   NWLY 500MB FLOW INCREASES EWD ACROSS CO...WITH 25-40KT WINDS LIKELY
   FROM WEST TO EAST ACROSS THE STATE. SURFACE WINDS MAY REACH 15-20
   MPH ACROSS CENTRAL/WRN CO FOR A TIME DURING THE AFTERNOON/EARLY
   EVENING...HOWEVER...WIND POTENTIAL IS NOT SIGNIFICANT ENOUGH TO
   WARRANT A RISK AREA AT THIS TIME.
