   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0351 AM CDT SAT SEP 30 2006
   
   VALID 301200Z - 011200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR WRN/CENTRAL MT...
   
   ...SYNOPSIS...
   A BREAKDOWN OF THE UPPER RIDGE WILL OCCUR TODAY OVER THE NRN ROCKIES
   AS AN UPPER SYSTEM MOVES FROM EWD FROM THE PAC NW COAST. AS THIS
   OCCURS...WLY WINDS WILL INCREASE OVER THE NRN ROCKIES...AND COMBINED
   WITH WARM TEMPERATURES/LOW RH READINGS WILL SUPPORT A CRITICAL FIRE
   WEATHER THREAT. MEANWHILE...SLY WINDS WILL BEGIN TO INCREASE OVER
   THE PLAINS AS A BROAD UPPER TROUGH IS REPLACED BY UPPER RIDGING.
   WIND SPEEDS SHOULD REMAIN BELOW CRITICAL LEVELS IN THIS REGION.
   ELSEWHERE ACROSS THE NATION...SFC HIGH PRESSURE WILL MOVE EWD ACROSS
   THE SERN STATES AND SUPPORT LOW HUMIDITIES AND LIGHT WINDS.
   
   ...CRITICAL FIRE WEATHER AREA - PORTIONS OF WRN/CENTRAL MT...
   
   PRIMARY CONDITIONS: SUSTAINED WLY WINDS FROM 20-25 MPH WITH GUSTS
   OVER 40 MPH...MIN RH READINGS NEAR 15 PERCENT...LONG TERM DROUGHT
   
   AS AN UPPER TROUGH OFF THE PAC NW COAST MOVES STEADILY EWD
   TODAY...THE UPPER RIDGE CURRENTLY OVER THE NRN ROCKIES WILL BREAK
   DOWN. ABOVE NORMAL TEMPERATURES AND LOW RH READINGS WILL AGAIN BE
   PRESENT OVER THE REGION AS DOWNSLOPE FLOW COUNTERACTS MID LEVEL
   COOLING. HOWEVER THE DOWNSLOPE WARMING WILL STEEPEN LOW LEVEL LAPSE
   RATES AND SUPPORT A WELL MIXED LOWER ATMOSPHERE. MODERATE MID LEVEL
   WIND FIELDS ARE ANTICIPATED TO MIX TOWARDS THE SURFACE SUPPORTING
   SUSTAINED WLY WINDS FROM 20-25 MPH WITH GUSTS OVER 40 MPH. THESE
   CONDITIONS WILL SUPPORT A CRITICAL FIRE WEATHER THREAT INTO THE
   EARLY EVENING HRS WHEN WINDS DIMINISH AND RH READINGS IMPROVE.
   
   ...SRN AL/GA AND NRN FL...
   NORTH OF A FRONT WHICH WILL REMAIN NEARLY STATIONARY OVER
   CENTRAL/SRN FL DURING THE PERIOD...AN AREA OF SFC HIGH PRESSURE AND
   ASSOCIATED DRY AIRMASS /DEWPTS IN THE 40S/ WILL EXIST OVER THE
   REGION. GENERALLY LIGHT NLY/ELY WINDS LESS THAN 10 MPH WILL PRECLUDE
   A CRITICAL FIRE WEATHER THREAT. ALTHOUGH RECENT BELOW AVERAGE
   PRECIPITATION AND LOW MIN RH READINGS FROM 25-30 PERCENT WILL
   SUPPORT A VERY HIGH FIRE DANGER.
   
   ...HIGH PLAINS...
   SLY WINDS WILL INCREASE TO AROUND 15 MPH DURING THE AFTERNOON TODAY
   IN RESPONSE TO STRENGTHENING LEE TROUGH AS UPPER RIDGE SHIFTS EWD
   FROM THE ROCKIES AND BREAKDOWNS. GENERALLY DRY AIR AND WELL ABOVE
   NORMAL TEMPERATURES WILL SUPPORT MIN RH READINGS FROM 15-20 PERCENT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0452 AM CDT SAT SEP 30 2006
   
   VALID 011200Z - 021200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR FOR DRY TSTMS FOR THE ERN GREAT
   BASIN...
   
   ...SYNOPSIS...
   TWO SRN STREAM UPPER TROUGHS WILL MOVE INTO SRN CA AND THE SRN GREAT
   BASIN THROUGH THE PERIOD. AHEAD OF THESE TROUGHS...STRONG FORCING
   COMBINED WITH MID LEVEL MOISTURE AND INSTABILITY WILL SUPPORT
   ISOLATED/SCT TSTMS OVER THE GREAT BASIN. CONDITIONS APPEAR FAVORABLE
   FOR A FEW DRY TSTMS CAPABLE OF PRODUCING GUSTY/ERRATIC WINDS AND
   POSSIBLE FIRE STARTS. FURTHER EAST...UPPER RIDGING WILL CONTINUE TO
   FLATTEN OVER THE PLAINS...SUPPORTING INCREASING MID LEVEL FLOW OVER
   THE CENTRAL ROCKIES. AS A RESULT...THE LEE TROUGH WILL DEEPEN OVER
   THE HIGH PLAINS. INCREASING SSWLY WINDS WILL OCCUR OVER THE SRN
   PLAINS. LIMITED MOISTURE RETURN WILL AID IN NEAR CRITICAL FIRE
   WEATHER CONDITIONS OVER MUCH OF THE TX PANHANDLE...WRN OK AND
   WRN/SRN KS.
   
   ...CRITICAL FIRE WEATHER AREA - ERN GREAT BASIN...
   
   PRIMARY CONDITIONS: SCT DRY TSTMS
   
   AS THE LEAD UPPER LEVEL SHORTWAVE MOVES INTO THE REGION DURING THE
   PERIOD...MODERATE MID LEVEL COOLING/DESTABILIZING WILL SUPPORT TSTM
   DEVELOPMENT DURING THE AFTERNOON/EVENING. DRY LOWER LEVELS /PWAT
   VALUES AROUND 0.60 IN./ ALONG WITH RELATIVELY FAST STORM MOTIONS
   WILL SUPPORT DRY TSTMS WITH LITTLE OR NO PRECIPITATION ACROSS ERN
   NV/WRN UT.
   
   ...SRN HIGH PLAINS...
   AS SFC LEE TROUGH STRENGTHENS TOMORROW THE SENSIBLE RESULT WILL BE
   AN INCREASE IN THE LOWER LEVEL WIND FIELDS/PRESSURE GRADIENT. WELL
   ABOVE NORMAL TEMPERATURES IN THE LOWER 90S AND LIMITED MOISTURE
   RETURNS /DEWPTS IN THE 40 AND LOWER 50S/ WILL SUPPORT MIN RH
   READINGS FROM 15-20 PERCENT. SUSTAINED WINDS FROM THE TX
   PANHANDLE...WRN OK AND SWRN KS WILL AVERAGE FROM 20-25 MPH
   SUPPORTING NEAR CRITICAL FIRE WEATHER CONDITIONS.
   
   ...SRN GREAT BASIN...
   UNCERTAINTY EXISTS ON THE AMT OF HIGH CLOUD COVER THAT WILL
   OVERSPREAD THE SRN GREAT BASIN IN ASSOCIATION WITH APPROACHING UPPER
   TROUGHS. IF LESS HIGH CLOUD COVER APPEARS POSSIBLE IN LATER
   OUTLOOK...THE SUSTAINED SWLY WINDS FROM 20-25 MPH AND LOW RH
   READINGS FROM 10-15 PERCENT WOULD SUPPORT A CRITICAL FIRE WEATHER
   THREAT.
   
   ...NRN FL...
   SURFACE FRONT WILL MOVE SWD INTO SRN FL. NORTH OF THIS FRONT...HIGH
   PRESSURE WILL GRADUALLY MOVE EWD. ANOTHER DAY OF LOW RH READINGS
   FROM 25-30 PERCENT WILL SUPPORT NEAR CRITICAL FIRE WEATHER
   CONDITIONS.
