   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0354 AM CDT TUE SEP 09 2003
   
   VALID 091200Z - 101200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A DEEP UPPER TROUGH WILL BECOME ENTRENCHED IN THE WRN CONUS THROUGH
   THE PERIOD...AS A STRONG UPPER LOW OFF THE ORE COAST AT THE START OF
   THE PERIOD MOVES SEWD INTO THE GREAT BASIN BY 10/12Z...AND A LEAD
   TROUGH MOVES NEWD FROM MT INTO SRN CANADA. SCT-NUMEROUS WET
   THUNDERSTORMS WILL BE FOUND AHEAD OF THE MAIN UPPER SYSTEM ACROSS
   MUCH OF THE ROCKIES/ADJACENT HIGH PLAINS. A SMALL AREA SOUTH OF THE
   MAIN COLD FRONT AND NOT AFFECTED BY CONVECTION...WILL EXIST OVER
   SERN CA/SRN NV AND FAR SWRN UT/NWRN AZ. HERE SFC WINDS/MIN RH
   READINGS WILL APPROACH CRITICAL LEVELS. OTHERWISE...EXPECT MODERATE
   WINDS/RH READINGS ACROSS THE REMAINDER OF THE WEST...WITH BELOW
   NORMAL TEMPERATURES BEHIND A COLD FRONT...WHICH WILL EXTEND FROM THE
   SRN SIERRA NV NEWD INTO THE NRN WY BY 10/00Z. STRONG SLY WINDS WILL
   AGAIN BE FOUND OVER THE PLAINS STATES...BUT MODERATE RH READINGS/LOW
   FIRE DANGERS WILL PRECLUDE ANY CRITICAL FIRE WEATHER THREAT.
   
   ....INTERIOR SRN/CENTRAL CA...SRN NV...FAR NWRN AZ/SWRN UT...
   BELT OF STRONGEST MID LEVEL FLOW WILL MOVE THROUGH THE AREA DURING
   THE DAY. STRONG SUSTAINED WINDS FROM 20 TO 30 MPH WITH GUSTS ABOVE
   40 MPH ACROSS HIGHER ELEVATIONS WILL BE LIKELY..ESPECIALLY OVER
   PORTIONS OF SERN CA/SWRN NV...WHERE MID LEVEL WIND MAX WILL PROGRESS
   ACROSS THE AREA DURING PEAK MIXING TIME. SCT CONVECTION IS
   ANTICIPATED TO DEVELOP OVER HIGHER ELEVATIONS OF NRN AZ/SRN UT. BUT
   LOWER ELEVATIONS AREA LIKELY TO SEE ONLY MID/HIGH CLOUDS. THE
   OVERALL AMOUNT OF UPSTREAM MID AND HIGH CLOUD COVER SEEN ON
   SATELLITE IMAGERY EARLY THIS MORNING...WHICH WILL MOVE INTO THE AREA
   DURING THE AFTERNOON...SHOULD MITIGATE AFTERNOON HIGH TEMPERATURES.
   THUS MIN RH READINGS ARE ANTICIPATED TO REMAIN IN THE 15 TO 25
   PERCENT RANGE...LIMITING ANY CRITICAL FIRE WEATHER THREAT.
   
   ...ERN MT/WRN ND...
   BEHIND DEPARTING UPPER LOW AS IT MOVES INTO CANADA...WLY WINDS WILL
   RANGE FROM 15 TO 20 MPH DURING THE AFTERNOON HOURS. MIN RH READINGS
   AROUND 30 PERCENT AND RECENT RAINFALL WILL LIMIT ANY CRITICAL FIRE
   WEATHER CONCERNS.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0459 AM CDT TUE SEP 09 2003
   
   VALID 101200Z - 111200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   UPPER LOW/TROUGH WILL REMAIN CENTERED OVER THE ROCKIES...WHILE WEAK
   UPPER RIDGING BUILDS INTO THE PAC NW. SCT WET THUNDERSTORMS WILL 
   REMAIN LIKELY OVER MUCH OF ROCKIES AND PLAINS NEAR/AHEAD OF THE
   TROUGH. AN ASSOCIATED SFC COLD FRONT WILL CONTINUE TO SLOWLY
   PROGRESS SEWD AND EXTEND FROM SRN CA/NRN AZ ENEWD INTO WRN KS BY
   11/12Z. NORTH OF THIS FRONT...BELOW NORMAL TEMPERATURES/MODERATE RH
   READINGS WILL PRECLUDE ANY FIRE WEATHER CONCERNS. SOUTH OF THIS
   BOUNDARY...SUSTAINED SWLY WINDS FROM 15 TO 25 MPH WILL BE POSSIBLE
   OVER SRN AZ/NM AND FAR WRN TX. BUT RECENT PRECIPITATION AND MARGINAL
   RH READINGS OVER THIS AREA WILL PRECLUDE ANY CRITICAL FIRE WEATHER
   THREAT.
   
   ...INTERIOR NRN/CENTRAL CA...
   SFC BOUNDARY IS FORECAST TO MAKE IT DOWN INTO SRN CA DURING THE
   PERIOD. NELY/DOWNSLOPE WINDS WILL AID IN LOW DEWPOINTS/RH READINGS
   SPREADING WWD OUT OF THE GREAT BASIN INTO MUCH OF CA DURING THE
   PERIOD. THERMAL GRADIENT BETWEEN INTERIOR NV/COASTAL AREAS WILL BE
   GREATEST AFTER 11/00Z. SUSTAINED WINDS FROM 10 TO 20 MPH WILL BE
   POSSIBLE DURING THE AFTERNOON...WITH STRONGER WINDS FORECAST
   OVERNIGHT...ESPECIALLY OVER NRN CA. PRECIPITATION DURING THE DAY ONE
   PERIOD WILL LIKELY LIMIT THE THREAT FOR ANY CRITICAL FIRE WEATHER ON
   DAY 2...DESPITE OTHER FAVORABLE PARAMETERS.
