   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0351 AM CDT SAT AUG 19 2006
   
   VALID 191200Z - 201200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   WARM AND DRY CONDITIONS WILL PERSIST ACROSS THE WRN STATES UNDER
   UPPER RIDGE...WHILE MONSOONAL RAINS CONTINUE FROM CO INTO NM. A COLD
   FRONT WILL TRAIL FROM THE OH VALLEY SWWD ACROSS OK AND INTO THE TX
   PANHANDLE THIS AFTERNOON BRINGING THUNDERSTORMS. SOUTH OF THIS
   FRONT...IT WILL REMAIN QUITE HOT WITH TEMPERATURES OVER 100 F FROM
   AR/LA INTO OK AND TX. DESPITE RELATIVELY WEAK WINDS...NEAR CRITICAL
   FIRE CONDITIONS WILL EXIST FROM SRN OK INTO NRN TX.
   
   ...SRN OK AND NRN TX...
   A COMBINATION OUTFLOW BOUNDARY/COLD FRONT WILL SINK SWD ACROSS
   CENTRAL OK...APPROACHING THE RED RIVER BY LATE IN THE DAY. SOUTH OF
   THIS BOUNDARY...IT WILL AGAIN BE VERY HOT WITH HIGHS ABOVE 100 F.
   THIS WILL CAUSE RH LEVELS TO DROP TO 20-30 PERCENT FROM SRN OK INTO
   NRN TX. THE STRONG HEATING AND MODERATELY LOW RH WILL PRODUCE A
   FAVORABLE ENVIRONMENT FOR FIRE GROWTH MAINLY DURING THE AFTERNOON.
   WIND SPEEDS SOUTH OF THE FRONT WILL ONLY AVERAGE AT OR BELOW 10 MPH
   OUT OF THE SE...HOWEVER...A WIND SHIFT WILL OCCUR IF THIS
   FRONT...POSSIBLY ENFORCED BY DAYTIME STORM OUTFLOW...SURGES
   SWD....POTENTIALLY CAUSING ERRATIC FIRE BEHAVIOR WITH ANY ONGOING
   FIRES.
   
   ...FAR NRN NV...
   STRONG HEATING ALONG WITH SOME INCREASE IN MID LEVEL MOISTURE MAY
   SPARK AN ISOLATED STORM OVER THE HIGH TERRAIN OF N-CNTRL NV. ANY
   STORMS THAT DO DEVELOP WILL BE DRY WITH POTENTIAL FOR FIRE STARTS.
   HOWEVER...OVERALL THREAT AND EXPECTED COVERAGE OF LIGHTNING IS MUCH
   TOO LOW FOR A CRITICAL AREA.

   VALID 201200Z - 211200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   HIGH PRESSURE WILL SETTLE ACROSS THE UPPER MS VALLEY ON SUN...WITH
   INCREASED SURFACE PRESSURE GRADIENT ACROSS WRN NEB AND THE DAKOTAS.
   FARTHER S...A FRONTAL BOUNDARY WILL EXTEND ALONG SRN PERIPHERY OF
   THE HIGH...FROM N CNTRL TX INTO THE TN VALLEY. SHOWERS AND

   SOUTH OF THIS FRONT...HOT AND DRY CONDITIONS WILL PERSIST ACROSS NRN
   AND ERN TX WITH MODERATELY LOW RH.
   
   ELSEWHERE...UPPER RIDGE WILL BUILD ALONG THE PACIFIC COAST STATES
   AHEAD OF A WEAK UPPER LOW OVER THE ERN PACIFIC. UNDER THIS
   RIDGE...VERY HOT AND DRY CONDITIONS WILL PREVAIL...ESPECIALLY WITHIN
   THERMAL RIDGE FROM THE LOWER CO RIVER VALLEY NWWD INTO THE GREAT
   BASIN AND WA...ORE...WRN ID.
   
   ...SRN OK INTO NRN TX...
   RH LEVELS WILL INCREASE IN ASSOCIATION WITH A COOL FRONT AS IT MOVES
   ACROSS SRN OK INTO NRN TX. MIN VALUES OF 30-35 PERCENT MAY OCCUR
   OVER NRN TX...WITH WINDS LESS THAN 10 MPH. IT WILL REMAIN
   WARM...WITH HIGHS NEAR 100 ALONG AND SOUTH OF I-20.
   
   ...WA/ORE/SWRN ID/WRN NV...
   A HIGH HAINES INDEX WILL DEVELOP SUNDAY BENEATH STRENGTHENING UPPER
   RIDGE. RH WILL AVERAGE NEAR 10 PERCENT AT PEAK HEATING REGION-WIDE
   WITH UPPER SINGLE DIGITS INTERMINGLED. WINDS MAY INCREASE TO 10-15
   MPH BY LATE AFTERNOON DUE TO STRONG TURBULENT MIXING...BUT WILL BE
   TOO WEAK FOR ANY SIGNIFICANT CRITICAL FIRE THREAT.
   
   IN ADDITION...A FEW LIGHTNING STRIKES MAY DEVELOP OVER THE OREGON
   CASCADES LATE IN THE DAY...BUT COVERAGE WILL BE ISOLATED AT BEST.
