   VALID 081200Z - 091200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR MUCH OF THE SRN ROCKIES/SRN HIGH
   PLAINS...
   ...CRITICAL FIRE WEATHER AREA FOR PORTION OF THE NRN PLAINS...
   
   ...SYNOPSIS...
   A STRONG UPPER TROUGH WILL CONTINUE TO DEVELOP OVER THE WRN CONUS
   THROUGH THE PERIOD. A LEAD SHORTWAVE TROUGH WILL EJECT OUT OF THE
   SWRN STATES INTO THE CENTRAL/NRN PLAINS BY THE END OF THE PERIOD.
   THE INCREASING WSWLY MID LEVEL FLOW WILL AID IN STRENGTHENING THE
   LEE TROUGH ALONG THE HIGH PLAINS. THE RESULTANT INCREASING PRESSURE
   GRADIENT BETWEEN THIS TROUGH AND HIGH PRESSURE OVER THE GREAT LAKES
   WILL AID IN SUSTAINED SLY WINDS FROM 20-25 MPH OVER MUCH OF THE HIGH
   PLAINS. OVER THE NRN HIGH PLAINS...VERY WARM TEMPERATURES IN THE
   LOWER 80S WILL COMBINE WITH MIN RH READINGS AROUND 20 PERCENT...LONG
   TERM DROUGHT/PRE-GREEN UP CONDITIONS TO LEAD TO A CRITICAL FIRE
   WEATHER THREAT. FARTHER SW...TO THE WEST OF THE LEE TROUGH OVER THE
   SRN HIGH PLAINS/SRN ROCKIES...STRONG WSWLY FLOW COMBINED WITH STEEP
   LAPSE RATES/MID LEVEL COOLING WILL SUPPORT SWLY WINDS FROM 20-30 MPH
   WITH GUSTS OVER 40 MPH. MIN RH READINGS IN THIS AREA WILL RANGE FROM
   10-15 PERCENT...LEADING TO A CRITICAL FIRE WEATHER THREAT. ELSEWHERE
   ACROSS THE ERN HALF OF THE NATION...THE COMBINATION OF A BROAD HIGH
   PRESSURE AREA OVER THE GREAT LAKES/NEW ENGLAND AND ASSOCIATED LIGHT
   WINDS AND SCT PRECIP ASSOCIATED WITH SERN UPPER SYSTEM WILL PRECLUDE
   ANY FIRE WEATHER CONCERNS.
   
   ...CRITICAL FIRE WEATHER AREA 1 - THE LOWER ELEVATIONS OF THE SRN
   ROCKIES...SRN HIGH PLAINS...
   
   PRIMARY CONDITIONS: SUSTAINED SWLY WINDS FROM 20-30 MPH WITH GUSTS
   OVER 40 MPH...MIN RH READINGS FROM 10-15 PERCENT
   
   A LEAD SHORTWAVE TROUGH WILL EJECT NEWD FROM AZ INTO THE CENTRAL
   PLAINS THROUGH THE PERIOD. ASSOCIATED STRONG MID LEVEL WIND FIELDS
   AND STEEP LOW-MID LEVEL LAPSE RATES WILL SUPPORT STRONG SWLY SFC
   WINDS FROM 20-30 MPH WITH GUSTS OVER 40 MPH. VERY DRY AIRMASS
   SUPPORTED BY DOWNWARD VERTICAL MOTION IN THE WAKE OF THE MID LEVEL
   TROUGH WILL AID IN MIN RH READINGS FROM 10-15 PERCENT. LONG TERM
   MOIST CONDITIONS WILL LIMIT THE CRITICAL FIRE WEATHER THREAT TO WIND
   DRIVEN GRASS-FIRES IN LOWER ELEVATIONS OF THE REGION.
   
   ...CRITICAL FIRE WEATHER AREA 2 - A PORTION OF THE NRN HIGH
   PLAINS...
   
   PRIMARY CONDITIONS: SUSTAINED SLY WINDS FROM 20-25 MPH...MIN RH
   READINGS AROUND 20 PERCENT...LONG TERM DROUGHT
   
   CRITICAL FIRE WEATHER CONDITIONS WILL OCCUR OVER MUCH OF WRN/CENTRAL
   ND/SD THIS AFTERNOON/EVENING TO THE EAST OF A COLD FRONT WHICH WILL
   MOVE TO THE MT/DAKOTA BORDER. TO THE EAST OF THE FRONT VERY WARM
   TEMPERATURES AND MOD SLY WINDS OVER 20 MPH WILL OCCUR DUE TO THE
   COMBINATION OF LOW LEVEL THERMAL RIDGE AND STRONG PRESSURE GRADIENT.
   VERY WARM TEMPERATURES IN THE 80S WILL COMBINE WITH DEWPTS IN THE
   30S TO PROVIDE FOR MIN RH READINGS AROUND 20 PERCENT. THE FRONT WILL
   MOVE INTO WRN ND/SD OVERNIGHT...BUT AHEAD OF THE FRONT...STRONG
   WINDS WILL MAINTAIN THE CRITICAL FIRE WEATHER THREAT FOR A FEW HOURS
   AFTER SUNSET.
   
   ...CENTRAL HIGH PLAINS SWD INTO WRN TX...
   DESPITE STRONG SLY WINDS FROM 20-30 MPH...MIN RH READINGS ARE FCST
   TO BE FROM 20-25 PERCENT OR JUST ABOVE CRITICAL LEVELS. IN
   ADDITION...ISOLATED DRY THUNDERSTORMS WILL BE POSSIBLE MAINLY OVER
   ERN CO/WRN KS NWD INTO WRN NEB...AHEAD OF THE LEE TROUGH LATE THIS
   AFTERNOON/EARLY EVENING.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0405 AM CDT FRI APR 08 2005
   
   VALID 091200Z - 101200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR SRN ROCKIES/SRN HIGH PLAINS...
   
   ...SYNOPSIS...
   A BROAD UPPER TROUGH WILL DEVELOP/MOVE SLOWLY ACROSS THE WRN CONUS.
   AN ASSOCIATED STRONG COLD FRONT WILL MOVE ACROSS MOST OF NM BY
   10/12Z. AHEAD OF THIS FRONT AND TO THE WEST OF A DRYLINE...WARM AND
   DRY READINGS AND STRONG SWLY WINDS WILL LEAD TO A CRITICAL FIRE
   WEATHER THREAT OVER SRN AZ NEWD ACROSS SRN/CENTRAL NM AND WRN TX.
   INCREASING SELY FLOW AND LOW RH READINGS AROUND A SFC HIGH CENTERED
   OVER THE ERN GREAT LAKES WILL SUPPORT NEAR CRITICAL FIRE WEATHER
   CONDITIONS OVER NRN WI AND PARTS OF MI. OTHERWISE...LIGHT WINDS AND
   OR MODERATE RH READINGS WILL OCCUR ACROSS THE NATION.
   
   ...CRITICAL FIRE WEATHER AREA 1 - SERN AZ...SRN/CENTRAL NM...WRN
   TX...
   
   PRIMARY CONDITIONS: SUSTAINED SWLY WINDS FROM 20-30 MPH...MIN RH
   READINGS AROUND 15 PERCENT
   
   DESPITE SOME COOLING...ESPECIALLY OVER NM/SERN AZ FROM DAY ONE TO
   DAY TWO...DUE TO PASSAGE OF LEAD SHORTWAVE TROUGH...SUFFICIENTLY DRY
   AIR WILL COUPLE WITH TEMPERATURES IN THE 60S/70S TO PRODUCE MIN RH
   READINGS AROUND 15 PERCENT. DEEP MIXING OF STRONG WINDS FIELDS ALOFT
   WILL LEAD TO ANOTHER WINDY DAY WITH SUSTAINED SFC WINDS FROM 20-30
   MPH. THE CRITICAL FIRE WEATHER THREAT WILL EXTEND AS FAR EAST AS WRN
   TX...TO THE WEST OF WHERE A SFC DRYLINE SHOULD RESIDE BY THE MID
   AFTERNOON HOURS.
   
   ...NRN WI...WRN/NRN MI...
   SELY LOW LEVEL WINDS WILL INCREASE TO BETWEEN 15 AND 20 MPH AS THE
   PRESSURE GRADIENT BEGINS TO STRENGTHEN IN RESPONSE TO APPROACHING
   PLAINS SYSTEM. LOW DEWPTS WILL COMBINE WITH ABOVE NORMAL
   TEMPERATURES IN THE 60S TO PRODUCE MIN RH READINGS AROUND 25 PERCENT
   OR SLIGHTLY ABOVE CRITICAL LEVELS.
