   VALID 091200Z - 101200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR MOST OF CENTRAL/ERN MT AND THE WRN
   DAKOTAS...
   
   ...SYNOPSIS...
   ZONAL FLOW WILL BE BEGIN TO AMPLIFY THROUGH THE PERIOD AS A STRONG
   UPPER TROUGH BEGINS TO DIG INTO THE WRN CONUS. A LEAD SHORTWAVE WILL
   MOVE THROUGH THE NRN PLAINS TODAY. STRONG WIND FIELDS ACCOMPANYING
   THIS TROUGH ALONG WITH MILD TEMPERATURES AND LOW RH READINGS WILL
   LEAD TO CRITICAL FIRE WEATHER CONDITIONS OVER THIS REGION.
   ELSEWHERE...WINDS WILL REMAIN LIGHT OVER THE WEST FOR ONE MORE
   DAY...WITH LOW RH READINGS. LOW RH READINGS WILL AGAIN BY FOUND OVER
   INTERIOR FL/GA AND SC...BUT SUSTAINED WINDS LESS THAN 15 MPH WILL
   AGAIN LIMIT A CRITICAL FIRE WEATHER OUTLOOK.
   
   ...CRITICAL FIRE WEATHER AREA 1 - MOST OF CENTRAL/ERN MT...WRN ND
   AND NWRN SD...
   
   PRIMARY CONDITIONS: SUSTAINED WINDS FROM 20 TO 25 MPH...MIN RH
   READINGS AROUND 20 PERCENT
   
   A STRONG MID/UPPER LEVEL SHORTWAVE TROUGH WILL MOVE ACROSS THE AREA
   EARLY IN THE PERIOD. BEHIND THIS SYSTEM A SURFACE TROUGH OF LOW
   PRESSURE...STEEP LOW-MID LEVEL LAPSE RATES WILL AID IN INCREASING
   WLY WINDS OVER THE REGION. A COLD FRONT WILL MOVE SWD OUT OF
   CANADA...BUT SHOULD NOT AFFECT MOST OF THE AREA UNTIL AFTER 00Z.
   RECENT WARM TEMPERATURES AND LACK OF APPRECIABLE RAINFALL/LONG TERM
   DROUGHT HAS WILL FURTHER EXACERBATE THE CRITICAL FIRE WEATHER
   THREAT...DESPITE MARGINAL LOW RH READINGS AROUND 20 PERCENT. THE
   CRITICAL FIRE WEATHER THREAT WILL END RAPIDLY OVER NCENTRAL/NERN MT
   AROUND 00Z WITH PASSAGE OF A COLD FRONT. WITH CONDITIONS IMPROVING
   ELSEWHERE THROUGH THE EVENING AS WINDS DIMINISH.
   
   ...INTERIOR FL/SRN GA AND CENTRAL SC...
   REGION REMAINS IN A PERSISTENT AREA OF HIGH PRESSURE FROM THE
   SURFACE TO UPPER LEVELS. LARGE SCALE SUBSIDENCE AND FEEDBACK OF LONG
   TERM DRIER THAN NORMAL CONDITIONS WILL CONTINUE TO SUPPORT LOWERING
   OF DEWPOINTS IN THE AFTERNOON. WITH TEMPERATURES FORECAST TO WARM
   INTO THE 85-90 DEGREE RANGE...MIN RH READINGS FROM 30 TO 35 PERCENT
   ARE AGAIN EXPECTED. DESPITE THE DRY CONDITIONS...LIGHT SELY WINDS
   LESS THAN 15 MPH DURING THE TIME OF LOWEST RH READINGS WILL PRECLUDE
   A CRITICAL FIRE WEATHER THREAT.

   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SRN GREAT BASIN
   AND AZ...
   
   ...SYNOPSIS...
   AN UPPER TROUGH WILL CONTINUE TO AMPLIFY OVER THE WRN STATES THROUGH
   THE PERIOD. STRONG WIND FIELDS WILL ACCOMPANY THIS SYSTEM OVER ALL
   OF THE GREAT BASIN AND MUCH OF THE WRN ROCKIES. HOWEVER...ONLY AREAS
   THAT ARE NOT IN GREEN UP WILL SEE A CRITICAL FIRE WEATHER
   THREAT...MAINLY OVER SRN NV/NRN AZ AND PORTIONS OF FAR SERN CA.
   MODERATE WINDS WILL BE POSSIBLE AS FAR EAST AS WRN CO/NWRN NM.
   FARTHER NORTH...SELY WINDS WILL INCREASE OVER THE NRN HIGH
   PLAINS...BUT MIN RH READINGS ARE FORECAST TO BE ABOVE CRITICAL
   LEVELS. ELSEWHERE ACROSS THE NATION...THE ONLY AREA OF LOW RH
   READINGS WILL RESIDE IN THE INTERIOR FL/GA REGION...WHERE WINDS WILL
   BE LIGHT AGAIN PRECLUDING A CRITICAL FIRE WEATHER THREAT
   
   ...CRITICAL FIRE WEATHER AREA 1 - SRN NV...NRN AZ AND SERN CA...
   
   PRIMARY CONDITIONS: SUSTAINED WINDS FROM 20 TO 30 MPH...WITH MIN RH
   READINGS FROM 6 TO 12 PERCENT
   
   STRONG SHORTWAVE TROUGH/LOW WILL MOVE SEWD INTO THE GREAT BASIN
   THROUGH THE PERIOD. INCREASING MID LEVEL WINDS AND STEEP LAPSE RATES
   WILL AID IN STRONG SUSTAINED WINDS DEVELOPING OVER THE AREA BY LATE
   MORNING. DRY AIRMASS WILL ALSO RESIDE AND THERMAL RIDGE WILL AID IN
   VERY LOW MIN RH READINGS BELOW 10 PERCENT OVER MOST OF THE AREA.
   WINDS WILL REMAIN MODERATE TO STRONG OVERNIGHT...MAINLY IN HIGHER
   ELEVATIONS...WITH RH RECOVERY EXPECTED TO BE POOR IN THESE AREAS.
   
   ...SWRN UT...

   HOURS. AREA MAY NEED TO BE UPGRADED IN LATER FORECASTS.
   
   ...WRN CO AND NWRN NM...
   SWLY WINDS FROM 15 TO 20 MPH ARE ANTICIPATED TO DEVELOP DURING THE
   AFTERNOON AHEAD OF DIGGING SHORTWAVE TROUGH OVER THE GREAT BASIN.
   DESPITE A VERY DRY AIRMASS WITH MIN RH READINGS FROM 8 TO 15 PERCENT
   ANTICIPATED...MARGINAL WIND SPEEDS CURRENTLY FORECAST WILL PRECLUDE
   A CRITICAL FIRE WEATHER THREAT THIS FAR IN ADVANCE.
