   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0318 AM CDT THU AUG 10 2006
   
   VALID 101200Z - 111200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR A PORTION OF THE NRN GREAT
   BASIN...
   ...CRITICAL FIRE WEATHER AREA FOR A PORTION OF THE INTERIOR PAC NW
   FOR DRY TSTMS...
   ...CRITICAL FIRE WEATHER AREA FOR A PORTION OF THE SRN PLAINS...
   
   ...SYNOPSIS...
   ANOTHER SEASONABLY STRONG UPPER TROUGH WILL MOVE INTO THE PAC NW
   TODAY. AHEAD OF AN ASSOCIATED COLD FRONT...GUSTY SWLY WINDS COMBINED
   WITH LOW RH READINGS WILL LEAD TO CRITICAL FIRE WEATHER CONDITIONS
   OVER THE PORTIONS OF THE NRN GREAT BASIN. IN ADDITION...SCT DRY
   TSTMS WILL ALSO BE POSSIBLE OVER ERN ORE INTO WRN ID LATE IN THE
   AFTERNOON/OVERNIGHT. FURTHER SE...ABOVE NORMAL TEMPERATURES WILL
   CONTINUE OVER MUCH OF THE SRN 1/2 OF THE COUNTRY SOUTH OF A COLD
   FRONT. INCREASING SLY WINDS ALONG WITH NEAR RECORD HIGH TEMPERATURES
   OVER OK/NRN TX WILL PRODUCE CRITICAL FIRE WEATHER CONDITIONS.
   
   ...CRITICAL FIRE WEATHER AREA - NERN CA...NRN NV...MUCH OF ERN
   ORE/SWRN ID...
   
   PRIMARY CONDITIONS: SWLY WINDS FROM 20-25 MPH...MIN RH READINGS FROM
   10-15 PERCENT
   
   AHEAD OF AN UPPER TROUGH AXIS THAT WILL MOVE THROUGH THE PAC NW
   DURING THE PERIOD...SWLY SFC WINDS WILL INCREASE OVER MUCH OF THE
   NRN GREAT BASIN AND INTERIOR PAC NW. ABOVE NORMAL TEMPERATURES IN
   THE 90S WILL SUPPORT LOW RH READINGS FROM 10-15 PERCENT AHEAD OF A
   COLD FRONT WHICH IS FCST TO MOVE THROUGH ERN ORE DURING THE
   AFTERNOON HRS. THE COMBINATION OF MODERATE WINDS FROM 20-25 MPH WITH
   THE LOW RH READINGS WILL SUPPORT A CRITICAL FIRE WEATHER THREAT.
   WITH THE PASSAGE OF A COLD FRONT...WINDS WILL SHIFT TO A NWLY
   DIRECTION WITH ONLY SLOWLY IMPROVING RH READINGS.
   
   ...CRITICAL FIRE WEATHER AREA - ERN ORE...PORTIONS OF WRN ID...
   
   PRIMARY CONDITIONS: SCT DRY TSTMS
   
   AHEAD OF THE UPPER TROUGH AXIS AND ALONG AND JUST AHEAD OF A COLD
   FRONT...MID LEVEL MOISTURE WILL SUPPORT SCT TSTM DEVELOPMENT. AS WAS
   MENTIONED IN THE PREVIOUS PARAGRAPH...MUCH OF ERN ORE INTO SWRN ID
   WILL SEE LOW RH READINGS. THE COMBINATION OF FOCUSED LIFT ALONG THE
   FRONT/UPPER TROUGH ABOVE A DEEPLY MIXED AND DRY BOUNDARY LAYER WILL
   SUPPORT A CRITICAL DRY TSTM THREAT. TSTMS SHOULD INITIALLY FORM OVER
   ERN ORE BEFORE MOVING INTO WRN ID DURING THE EVENING/OVERNIGHT HRS.
   
   ...CRITICAL FIRE WEATHER AREA - ALL OF CENTRAL/WRN
   OK...NCENTRAL/NWRN  TX AND THE ERN TX PANHANDLE...
   
   PRIMARY CONDITIONS: SWLY WINDS FROM 15-20 MPH WITH GUSTS UP TO 25
   MPH...LONG TERM DROUGHT...MIN RH READINGS FROM 15-20
   PERCENT...ISOLATED  DRY TSTMS
   
   MODERATE LOW LEVEL JET EARLY THIS MORNING WAS SUPPORTING SUSTAINED
   WINDS FROM 10-15 WITH OCCASIONAL GUSTS OVER 20 MPH. ONLY MODEST RH
   RECOVERY WILL OCCUR THROUGH THE REMAINDER OF THIS MORNING BEFORE
   ANOTHER HOT DAY OVER MUCH OF THE SRN PLAINS. AS THE UPPER TROUGH
   OVER THE NRN PLAINS AT THE START OF THE PERIOD MOVES ESEWD INTO THE
   UPPER MIDWEST...A COLD FRONT WILL BE PUSHED SWD INTO KS. A LOW
   PRESSURE AREA IS ANTICIPATED TO BE LOCATED ALONG THE FRONT OVER FAR
   NWRN OK/SWRN KS BY THE AFTERNOON. MEANWHILE...HIGH PRESSURE WILL
   REMAIN IN NEARLY THE SAME LOCATION AS THE LAST FEW DAYS OVER THE
   NCENTRAL GULF COAST. THE RESULTANT PRESSURE GRADIENT ALONG WILL
   SUPPORT SUSTAINED SSWLY WINDS FROM 15-20 MPH WITH OCCASIONAL GUSTS
   OVER 25 MPH. GIVEN THE SWLY COMPONENT TO THE SFC WIND FIELDS...VERY
   HOT TEMPERATURES ARE EXPECTED WITH NEAR RECORD READINGS FROM 105-110
   DEG F. DEEP MIXING AND NEGATIVE FEEDBACK SOIL MOISTURE EFFECTS WILL
   SUPPORT DEWPTS IN THE UPPER 40S/LOWER 50S DURING THE AFTERNOON AND
   MIN RH READINGS FROM 15-20 PERCENT. DESPITE MARGINAL WIND
   FIELDS...THE EXCESSIVE HEAT/LOW RH READINGS AND LONG TERM DROUGHT
   SUPPORTS A CRITICAL FIRE WEATHER THREAT. IN ADDITION...ISOLATED
   REMNANT TSTMS MAY MOVE INTO THE ERN TX PANHANDLE/NWRN TX AND FAR WRN
   OK LATE TONIGHT. GIVEN RELATIVELY HIGH CLOUD BASES AND LIKELY
   WEAKENING TREND...SOME OF THESE STORMS MAY PRODUCE LITTLE RAIN.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0321 AM CDT THU AUG 10 2006
   
   VALID 111200Z - 121200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR THE NRN/ERN GREAT BASIN FOR SCT
   DRY TSTMS...
   ...CRITICAL FIRE WEATHER AREA FOR MUCH OF THE NRN ROCKIES...NRN HIGH
   PLAINS AND THE NRN GREAT BASIN...
   ...CRITICAL FIRE WEATHER AREA FOR NRN TX AND SRN OK...
   
   ...SYNOPSIS...
   AN UPPER TROUGH WILL MOVE FROM THE PAC NW INTO THE NRN ROCKIES
   THROUGH THE PERIOD. IN ASSOCIATION WITH THIS SYSTEM...MODERATE SWLY
   SFC WINDS WILL DEVELOP FROM THE NERN GREAT BASIN INTO PORTIONS OF
   THE NRN ROCKIES/NRN HIGH PLAINS. ALSO SCT DRY TSTMS WILL ARE
   EXPECTED AHEAD OF THE UPPER TROUGH AND ALONG A COLD FRONT AS IT
   MOVES THROUGH THE NRN/NERN GREAT BASIN DURING THE AFTERNOON INTO THE
   OVERNIGHT HRS. FURTHER SOUTH...UPPER RIDGING WILL REMAIN IN CONTROL
   OVER MUCH OF THE SRN TIER OF STATES. AS AN UPPER TROUGH SLIDES
   AROUND THE UPPER RIDGE INTO THE SERN STATES...A COLD FRONT WILL PUSH
   SWD INTO OK/TX PANHANDLE DURING THE DAY. SOUTH OF THE FRONT...HOT
   TEMPERATURES/LOW RH READINGS AND MODEST WINDS WILL LEAD TO ANOTHER
   CRITICAL FIRE WEATHER THREAT OVER SRN OK/NRN TX.
   
   ...CRITICAL FIRE WEATHER AREA - MUCH OF THE NRN ROCKIES/NRN HIGH
   PLAINS SWWD INTO THE NRN GREAT BASIN...
   
   PRIMARY CONDITIONS: SUSTAINED SWLY WINDS FROM 20-25 MPH...MIN RH
   READINGS FROM 5-15 PERCENT...COLD FRONTAL PASSAGE
   
   APPROACHING UPPER TROUGH AND INCREASING MID LEVEL WIND FIELDS WILL
   SUPPORT SUSTAINED SWLY WINDS FROM 20-25 MPH FROM ERN ID THROUGH MUCH
   OF WRN/NRN WY AND THE ERN HALF OF MT. LOW RH READINGS WILL BE
   COMMONPLACE WEST OF A LEE TROUGH THAT IS FORECAST TO BE ALONG THE
   ND/MT BORDER DURING THE AFTERNOON. A COLD FRONT WILL MOVE FROM NW-SE
   ACROSS WRN PORTIONS OF THE OUTLOOK AREA DURING THE AFTERNOON HRS.
   ALTHOUGH TEMPERATURES WILL COOL WITH THE FRONTAL PASSAGE...THE
   COOLING WILL BE LIMITED. WITH THE FRONTAL PASSAGE WINDS WILL SWITCH
   TO NWLY AND REMAIN MODERATE FOR SEVERAL HRS...CONTINUING CRITICAL
   FIRE WEATHER CONDITIONS.
   
   ...CRITICAL FIRE WEATHER AREA - PORTIONS OF NV/UT AND SRN ID...
   
   PRIMARY CONDITIONS: SCT DRY TSTMS
   
   AHEAD OF THE COLD FRONT...SCT TSTMS ARE EXPECTED TO DEVELOP FROM
   CENTRAL NV NEWD INTO SCENTRAL ID DURING THE AFTERNOON HRS. FCST
   SOUNDINGS ARE SUPPORTIVE OF LITTLE RAINFALL REACHING THE SFC WITH
   THESE TSTMS. AS THE FRONT PROGRESSES SEWD...DRY TSTMS WILL MOVE INTO
   PORTIONS OF SERN ID AND NRN UT DURING THE EVENING HRS.
   
   ...CRITICAL FIRE WEATHER AREA - SRN OK/NRN TX...
   
   PRIMARY CONDITIONS: SUSTAINED SSWLY WINDS FROM 15-20 MPH...MIN RH
   READINGS FROM 15-20 PERCENT...LONG TERM DROUGHT
   
   SOUTH OF A SLOW MOVING COLD FRONT...ANOTHER HOT DAY IS EXPECTED OVER
   SRN OK/NRN TX WITH HIGH TEMPERATURES IN THE 104-109 DEG F RANGE.
   DEEP MIXING WILL AGAIN SUPPORT DEWPTS FALLING INTO THE UPPER
   40S/LOWER 50S WITH MIN RH READINGS FROM 15-20 PERCENT DURING THE
   AFTERNOON. SWLY WIND SPEEDS ARE EXPECTED TO REMAIN SIMILAR TO DAY
   ONE /15-20 MPH WITH GUSTS UP TO 25 MPH/. ALTHOUGH THESE WIND SPEEDS
   ARE MARGINAL...THE DEGREE OF LONG TERM DROUGHT COUPLED WITH VERY LOW
   RH READINGS AND FAIR OVERNIGHT RH RECOVERY LATE ON DAY ONE SUPPORTS
   A CRITICAL FIRE WEATHER THREAT FOR DAY TWO.
