   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0339 AM CDT TUE JUL 25 2006
   
   VALID 251200Z - 261200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   EARLY MORNING WATER VAPOR IMAGES SHOW IMPULSE APPROACHING WRN
   MANITOBA AND ANOTHER WAVE NEAR WRN BC. MONSOONAL MOISTURE CONTINUES
   TO CIRCULATE AROUND THE LARGE UPPER LEVEL RIDGE IN THE WEST. HOWEVER
   MID LEVEL DRYING WILL SUPPRESS TSTM DEVELOPMENT ACROSS NW ORE AND
   MUCH OF WA TODAY. SCATTERED...MAINLY WET TSTMS ARE EXPECTED ACROSS
   THE FOUR CORNERS REGION THROUGH THE NRN ROCKIES. ISOLD DRY TSTMS ARE
   POSSIBLE ACROSS THE NRN GREAT BASIN AS LARGE SCALE LIFT WILL BE
   SLIGHTLY ENHANCED BY PASSING WAVE. ELSEWHERE...INCREASING PRESSURE
   GRADIENT ACROSS THE PLAINS ASSOCIATED WITH LEE TROUGH WILL RESULT IN
   BREEZY SFC WINDS.
   
   ...SERN ORE/NRN CA/NRN NV/SRN ID...
   MAX TEMPS WILL AGAIN RANGE IN THE 90S TO AROUND 100 WITH MIN RH
   VALUES BELOW 20 PERCENT. AXIS OF STEEPEST MID LEVEL LAPSE RATES WILL
   EXTEND FROM EXTREME NERN CA ACROSS NRN NV BY LATE AFTN. EXPERIMENTAL
   DRY LIGHTNING GUIDANCE SUGGESTS NRN NV/THE SAWTOOTH MTNS/WRN MT WILL
   BE MOST FAVORABLE AREAS FOR ISOLD DRY TSTMS TODAY. LIGHTNING
   COVERAGE IS NOT EXPECTED TO BE GREAT ENOUGH TO WARRANT AN OUTLOOK.
   HOWEVER...DUE TO VERY DRY FUELS AND HIGH LIGHTNING IGNITION
   EFFICIENCY...ANY LIGHTNING STRIKES WILL POSE A THREAT. GUSTY TSTM
   OUTFLOW WINDS WILL ALSO OCCUR NEAR STORMS.
   
   ...SRN PLAINS...
   SOUTH WINDS WILL INCREASE INTO THE 15-25 MPH RANGE TODAY...WITH
   RELATIVELY LOW RH VALUES BELOW 25 PERCENT. GIVEN SEVERE TO EXTREME
   LONG TERM DROUGHT...THERE WILL BE AN INCREASED THREAT FOR WIND
   DRIVEN WILDFIRE SHOULD IGNITIONS OCCUR.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0342 AM CDT TUE JUL 25 2006
   
   VALID 261200Z - 271200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   LEAD IMPULSE NOW OVER MANITOBA WILL MOVE EWD INTO NWRN ONTARIO BY
   EARLY THU. MEANWHILE ANOTHER WAVE WILL AFFECT THE HIGH
   PLAINS...LIKELY TRIGGERING HIGH BASED TSTMS IN THE AFTN/EVENING.
   INCREASED THREAT FOR WILDFIRE WILL CONTINUE ACROSS THE SRN PLAINS
   WITH MODERATE TO STRONG SFC WINDS. ACROSS THE NORTHWEST...DRY AIR IN
   THE MID-LEVELS COMBINED WITH SUBSIDENCE ASSOCIATED WITH THE UPPER
   RIDGE WILL INHIBIT TSTM DEVELOPMENT. GREATEST COVERAGE OF STORMS IS
   EXPECTED TO BE ACROSS THE SIERRA AND SRN/ERN GREAT BASIN EWD ACROSS
   THE INTERMOUNTAIN REGION.
   
   ...CNTRL/ERN MT...
   POST FRONTAL WINDS WILL INCREASE ON WED...AS TEMPS CLIMB INTO THE
   MID/UPPER 90S. WITH TEMP/DEWPOINT SPREADS ON THE ORDER OF 50-60
   DEGREES IN SOME LOCATIONS...MIN RH VALUES WILL FALL BELOW 15
   PERCENT. IN ADDITION TO THE LOW RH/INCREASED WIND...HIGH BASED TSTMS
   MAY FORM IN ERN MT WITH THE POTENTIAL FOR ISOLD DRY LIGHTNING AND
   GUSTY WINDS.
