   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0318 AM CDT MON JUL 24 2006
   
   VALID 241200Z - 251200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   UPPER RIDGE OVER THE WRN CONUS WILL BE SUPPRESSED SOME TODAY AS AN
   UPPER TROUGH APPROACHES THE WEST COAST AND SEVERAL WEAKER SYSTEMS
   MOVE EWD ALONG THE WRN CANADIAN BORDER. UNDER THE INFLUENCE OF THE
   UPPER RIDGE...HOT/NEAR RECORD TEMPERATURES WILL AGAIN OCCUR OVER
   MUCH OF THE WEST WITH A SLIGHT DECREASE IN TEMPERATURES NOTED ALONG
   THE COASTAL PLAINS/VALLEYS. SCT-NMRS TSTMS WILL CONTINUE OVER MOST
   OF THE INTERMTN REGION...AS MONSOONAL MOISTURE REMAINS ENTRENCHED
   AROUND THE UPPER RIDGE. A FEW STORMS MAY BE DRY OVER NRN/WRN
   PORTIONS OF THE MONSOONAL MOISTURE PLUME...BUT THE OVERALL COVERAGE
   IS NOT ANTICIPATED TO BE SUFFICIENT TO WARRANT A CRITICAL FIRE
   WEATHER THREAT.
   
   ...ERN WA/NRN ID...
   ALONG THE NRN PERIPHERY OF THE UPPER RIDGE AND MONSOONAL
   MOISTURE...ISOLATED TSTMS WILL DEVELOP OVER THE REGION. FORECAST
   SOUNDINGS SUGGEST ENOUGH MID LEVEL MOISTURE WILL EXIST ABOVE A VERY
   DEEPLY MIXED BOUNDARY LAYER /TEMPERATURES IN THE 100S/ THAT TSTMS
   WILL INITIALLY BE DRY. A LACK OF GREATER COVERAGE OF TSTMS AND A
   TRANSITION TO A MIX OF WET/DRY TSTMS WILL PRECLUDE A CRITICAL FIRE
   WEATHER THREAT. 
   
   ...INTERIOR NRN/CENTRAL CA AND ORE...
   ISOLATED TO SCT /INITIALLY DRY/ TSTMS SHOULD AGAIN DEVELOP ALONG THE
   HIGHER TERRAIN THIS AFTERNOON. AMT OF MID LEVEL MOISTURE NOTED ON
   LAST NIGHTS RENO...OAKLAND AND MEDFORD SOUNDINGS /PRECIPITABLE WATER
   VALUES OVER 1 INCH/ SUGGESTS THAT CONVECTION WILL BECOME WET WITH
   TIME. ADDITIONALLY...AN APPROACHING UPPER TROUGH WILL ACT TO SLOWLY
   DEEPEN THE MARINE LAYER AND SUPPORT AN INCREASING PRESSURE GRADIENT
   AND SUSTAINED WLY WINDS FROM 15-20 MPH DURING THE LATE AFTERNOON
   ACROSS THE COASTAL VALLEYS. WITH ONE MORE DAY OF HOT TEMPERATURES
   EXPECTED IN THESE AREAS...HIGHS FROM 95-105 F...MIN RH READINGS WILL
   AVERAGE FROM 20-25 PERCENT.
   
   ...SRN HIGH PLAINS...
   AS SFC HIGH PRESSURE MOVES SLOWLY EWD INTO THE OHIO VALLEY...THE SFC
   PRESSURE GRADIENT WILL INTENSIFY AS THE LEE TROUGH DEEPENS ALONG THE
   FRONT RANGE. THE RESULTANT PRESSURE GRADIENT WILL SUPPORT SLY WINDS
   FROM 15-20 MPH. MOISTURE RETURN WILL REMAIN SOMEWHAT LIMITED WITH
   DEWPTS IN LOWER-MID 50S. WITH HIGH TEMPERATURES IN THE 90S...MIN RH
   READINGS WILL FALL TO AROUND 20 PERCENT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0320 AM CDT MON JUL 24 2006
   
   VALID 251200Z - 261200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   THE UPPER RIDGE OVER THE WEST WILL CONTINUE TO BE SLOWLY SUPPRESSED
   SWD AS A FEW UPPER TROUGHS MOVE ALONG THE U.S/CANADIAN BORDER. WITH
   UPPER TROUGHING REMAINING OFF THE WEST COAST...A COOLING TREND WILL
   CONTINUE/COMMENCE OVER INTERIOR CA/ORE AND WA. CLOSER TO THE UPPER
   RIDGE AXIS...VERY WARM TEMPERATURES WILL AGAIN BE POSSIBLE OVER MOST
   OF THE ROCKIES REGION. IN ADDITION...SCT TSTMS WILL BE FOUND OVER
   MUCH OF THE WEST. MOST TSTMS WILL BE WET...BUT A FEW DRY TSTMS WILL
   BE POSSIBLE OVER THE NRN GREAT BASIN WHERE SLIGHT MID LEVEL DRYING
   IS EXPECTED. ELSEWHERE ACROSS THE NATION...ANOTHER DRY/BREEZY DAY
   WILL OCCUR OVER THE SRN PLAINS SUPPORTING NEAR CRITICAL FIRE WEATHER
   THREAT.
   
   ...FAR NRN CA...ERN ORE...NWRN NV AND WRN ID...
   WITH THE APPROACHING UPPER TROUGH SOME MID LEVEL DRYING IS EXPECTED.
   HOWEVER...ENOUGH MOISTURE WILL REMAIN THAT TSTMS ARE EXPECTED TO
   DEVELOP OVER THE SRN CASCADES INTO THE HIGHER TERRAIN OF ERN
   ORE/NWRN NV AND EVENTUALLY WRN ID. FORECAST SOUNDINGS INDICATE
   SLIGHTLY MORE FAVORABLE CONDITIONS FOR PURELY DRY TSTMS THAN ON DAY
   ONE...WITH PRECIP WATER VALUES FROM 3/4 TO 1 INCH AND THE PRESENCE
   OF VERY WARM TEMPERATURES/DEEPLY MIXED ENVIRONMENT. WITH FORECAST
   MODERATE SYNOPTIC FORCING WITH THE UPPER TROUGH...CONDITIONS MAY BE
   SUFFICIENT FOR SCT DRY TSTMS. THEREFORE THE AREA WILL BE MONITORED
   FOR A POSSIBLE UPGRADE.
   
   ...SRN HIGH PLAINS...
   ANOTHER WARM DAY WITH TEMPERATURES FROM 95-100 F AND DEWPTS IN THE
   50S WILL SUPPORT MIN RH READINGS AROUND 20 PERCENT. A MODERATE
   PRESSURE GRADIENT AND REMNANT LOW LEVEL JET WILL SUPPORT SLY WINDS
   AROUND 20 MPH WITH HIGHER GUSTS DURING THE AFTERNOON.
