   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE CENTRAL ROCKIES
   SWD INTO THE SRN GREAT BASIN...
   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SRN/CENTRAL HIGH
   PLAINS...
   
   ...SYNOPSIS...
   BROAD UPPER TROUGH WILL DIG SEWD INTO THE WRN CONUS THROUGH THE
   PERIOD. STRENGTHENING WIND FIELDS IN THE LOW TO MID LEVELS COUPLED
   WITH DRY LOW LEVELS WILL GENERATE CRITICAL FIRE WEATHER CONDITIONS
   OVER THE CENTRAL ROCKIES/ADJACENT HIGH PLAINS SWWD INTO THE FOUR
   CORNERS REGION. ELSEWHERE ACROSS THE NATION...MOIST LOW LEVELS OR
   LIGHT WINDS WILL PRECLUDE ANY CRITICAL FIRE WEATHER THREATS.
   
   ...CRITICAL FIRE WEATHER AREA 1 - FAR SRN NV/NRN AZ NEWD INTO WRN
   AND CENTRAL CO...
   
   PRIMARY CONDITIONS: SUSTAINED WINDS FROM 20 TO 30 MPH WITH GUSTS
   OVER 40 MPH...MIN RH READINGS FROM 10 TO 15 PERCENT.
   
   STRENGTHENING MID LEVEL WIND FIELDS ALONG WITH A DEEPENING SFC LOW
   PRESSURE AREA OVER WY AND STEEP LOW LEVEL LAPSE RATES WILL AID IN
   SUSTAINED SWLY WINDS FROM 20 TO 30 MPH WITH GUSTS OVER 40 MPH AHEAD
   OF AN ADVANCING COLD FRONT THAT WILL MOVE SEWD TO A SRN NV/NERN UT
   LINE BY 00Z. THE STRONGEST WINDS ARE FORECAST TO OCCUR FROM SWRN UT
   INTO NERN UT/NWRN CO NEAREST TO THE MID LEVEL WIND SPEED MAX. WINDS
   WILL REMAIN STRONG OVERNIGHT ESPECIALLY OVER THE HIGHER TERRAIN IN
   THE VICINITY OF THE FRONTAL BOUNDARY EXTENDING FROM NERN AZ INTO
   SCENTRAL CO. FARTHER NW...OVER MOST OF ERN UT AND NWRN CO...COLD
   FRONTAL PASSAGE ALONG WITH THE POTENTIAL FOR LIGHT PRECIPITATION
   WILL LIMIT THE CRITICAL FIRE WEATHER THREAT TO THE DAYLIGHT HOURS.
   
   ...CRITICAL FIRE WEATHER AREA 2 - NERN NM AND ERN CO...
   
   PRIMARY CONDITIONS: SUSTAINED WINDS FROM 20 TO 25 MPH WITH GUSTS
   OVER 35 MPH...MIN RH READINGS AROUND 15 PERCENT
   
   INCREASING SLY WINDS FROM 20 TO 25 MPH WILL OCCUR BY THE AFTERNOON
   OVER HIGH PLAINS REGION OF ERN CO/NERN NM AS AN AREA OF LOW PRESSURE
   DEEPENS OVER THE NERN WY/SERN MT AREA. LOW RH READINGS AROUND 15
   PERCENT WILL BE PRESENT COINCIDENT WITH THE SFC THERMAL RIDGE
   CENTERED OVER THE AREA AND LACK OF LOW LEVEL MOISTURE RETURN WITH
   DEWPOINTS MIXING INTO THE 20S WILL EXACERBATE CRITICAL FIRE WEATHER
   CONDITIONS GIVEN THE EXPECTED WINDS. ADDITIONALLY THERE IS THE
   POTENTIAL FOR ISOLATED DRY THUNDERSTORMS ALONG THE NRN ROCKY MTN
   FRONT RANGE...WHERE INCREASING LARGE SCALE LIFT INTERACTS WITH MID
   LEVEL MOISTURE. LFCS BETWEEN 550-500 MB AND PRECIPITABLE WATER
   VALUES OF 0.50 INCH WOULD ALLOW FOR LITTLE TO NO PRECIP REACHING THE
    GROUND WITH ANY STORMS. POOR RH RECOVERY IS ANTICIPATED OVER MOST
   OF THE AREA OVERNIGHT...EXCEPT OVER FAR NRN CO WHERE A COLD FRONTAL
   PASSAGE IS ANTICIPATED AFTER MIDNIGHT.

   ZCZC SPCFWDDY2 ALL
   FNUS22 KWNS 280957
   
   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0457 AM CDT FRI MAY 28 2004
   
   VALID 291200Z - 301200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR MUCH OF THE SRN ROCKIES...
   
   ...SYNOPSIS...
   A STRONG AND BROAD UPPER TROUGH WILL CONTINUE TO DIG SLIGHTLY OVER
   THE WRN CONUS THROUGH DAY 2....WHILE BEGINNING TO SLOWLY MOVE EWD
   INTO THE PLAINS BY THE END OF THE PERIOD. MODERATE WIND FIELDS WILL
   ACCOMPANY THIS TROUGH AGAIN AS ON DAY ONE BUT OVER AREAS FURTHER SE
   THAN ON DAY ONE...NAMELY THE SRN ROCKIES. AS ON DAY ONE...LOW RH
   READINGS WILL ACCOMPANY THESE WINDS AND PROVIDE FOR A CRITICAL FIRE
   WEATHER THREAT TO MUCH OF THIS REGION. ON THE SW PORTION OF THE
   TROUGH...GUSTY WLY WINDS AND LOW RH READINGS WILL BE FOUND OVER THE
   LOWER CO RIVER VALLEY...BUT CONDITIONS SHOULD REMAIN BELOW CRITICAL
   LEVELS. ELSEWHERE ACROSS THE NATION...EITHER MODERATE/HIGH RH
   READINGS OR LIGHT WINDS WILL PRECLUDE ANY CRITICAL FIRE WEATHER
   THREATS.
   
   ...CRITICAL FIRE WEATHER AREA 1 - NERN AZ...MOST OF NM...
   
   PRIMARY CONDITIONS: SUSTAINED WINDS FROM 20 TO 25 MPH...MIN RH
   READINGS FROM 10-15 PERCENT.
   
   UPPER TROUGH AXIS WILL PROGRESS EWD ACROSS THE ROCKIES THROUGH THE
   PERIOD. STRONG MID LEVEL WINDS WILL ACCOMPANY THIS TROUGH AND
   COMBINED WITH STEEP LAPSE RATES IN THE LOW-MID LEVELS WILL AID IN
   MODERATE WINDS TO DEVELOP OVER THE AREA BY THE LATE MORNING. THE
   STRONGEST SUSTAINED WLY WINDS FROM 20-30 MPH ARE ANTICIPATED OVER
   CENTRAL/ERN NM CLOSER TO THE MID LEVEL SPEED MAX DURING THE PEAK
   HEATING HOURS. ABOVE NORMAL TEMPERATURES COMBINED WITH SEASONABLY
   LOW DEWPOINTS WILL PRODUCE MIN RH READINGS FROM 10-15 PERCENT.
   COMBINED WITH THE WINDS...A CRITICAL FIRE WEATHER THREAT WILL EXIST.
   STRONG WINDS WILL CONTINUE OVER CENTRAL/ERN NM OVERNIGHT ALLOWING
   FOR POOR RH RECOVERY IN THESE AREAS.
   
   ....SCENTRAL/SERN CO...FAR NRN NM...
   CLOSER TO THE SURFACE LOW...WINDS ARE FORECAST TO BE LIGHTER THAN ON
   DAY ONE OVER THE AREA. HOWEVER...BEFORE THE COLD FRONTAL
   PASSAGE...VERY LOW DEWPOINTS/WARM TEMPERATURES WILL PRODUCE MIN RH
   READINGS FROM 10-15 PERCENT. STRONG MID-UPPER LEVEL FLOW AND NEAR
   DRY ADIABATIC LAPSE RATES THROUGH 500 MB WILL ALLOW FOR A HIGH
   HAINES INDEX AND POTENTIAL FOR PLUME DOMINATED FIRE GROWTH.
   ADDITIONALLY...ISOLATED DRY THUNDERSTORMS WILL BE POSSIBLE ALONG THE
   FRONT RANGE OF SRN CO DURING THE AFTERNOON...SPREADING EWD INTO THE
   LOWER ELEVATIONS OF SERN CO BY THE EVENING.
   
   ...WRN TX...
   STRONG WLY WINDS FROM 20 TO 30 MPH ARE LIKELY BEHIND A SURGING
   DRYLINE DURING THE MID MORNING THROUGH THE AFTERNOON. LACK OF HIGH
   FIRE DANGERS WILL PRECLUDE A CRITICAL FIRE WEATHER THREAT DESPITE
   MIN RH READINGS AROUND 15 PERCENT.
