   DAY 1 FIRE WEATHER OUTLOOK

   0322 AM CDT TUE AUG 08 2006
   
   VALID 081200Z - 091200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR MUCH OF MT AND PORTIONS OF ID FOR
   DRY THUNDERSTORMS...
   ...CRITICAL FIRE WEATHER AREA FOR MUCH OF THE ERN GREAT BASIN...
   
   ...SYNOPSIS...
   A PROGRESSIVE AND SEASONABLY STRONG UPPER TROUGH WILL LIFT NEWD FROM
   THE NWRN GREAT BASIN/CASCADES INTO THE NRN ROCKIES THROUGH THE
   PERIOD. AHEAD OF THIS TROUGH...GUSTY SWLY WINDS COMBINED WITH LOW RH
   READINGS WILL DEVELOP OVER THE ERN GREAT BASIN. FURTHER NORTH...MID
   LEVEL MOISTURE WILL INTERACT WITH THE TROUGH AND  PRODUCE SCT TSTMS
   OVER MUCH OF THE NRN ROCKIES/INTERIOR PAC NW THROUGH THE PERIOD.
   WHILE SOME OF THESE STORMS ARE EXPECTED TO BE WET OVER WRN MT/FAR
   NRN ID...THERE SHOULD BE A ZONE OF MAINLY DRY TSTMS OVER MUCH OF THE
   REMAINDER OF MT AND PORTIONS OF CENTRAL/SRN ID.
   
   ELSEWHERE ACROSS THE NATION...SCT TSTMS ARE EXPECTED OVER MUCH OF
   THE CENTRAL/SRN ROCKIES ASSOCIATED WITH MONSOONAL MOISTURE. AHEAD OF
   THE UPPER TROUGH...MODERATE SLY WINDS WILL DEVELOP OVER THE NRN
   PLAINS. FURTHER SOUTH...THE UPPER RIDGE WILL REMAIN MOSTLY IN
   CONTROL OVER THE SRN PLAINS. SOME RELIEF WILL BE PRESENT
   HOWEVER...AS A WEAK UPPER SYSTEM SUPPORTS ISOLATED TSTMS OVER NRN
   TX/OK.
   
   ...CRITICAL FIRE WEATHER AREA - MUCH OF MT AND PORTIONS OF ID FOR
   DRY TSTMS...
   
   PRIMARY CONDITIONS: SCT DRY TSTMS WITH STRONG ERRATIC WINDS
   
   AS THE UPPER TROUGH CENTERED OVER THE SRN CASCADES EARLY THIS
   MORNING MOVES ENEWD INTO THE NRN ROCKIES THROUGH THE
   PERIOD...INCREASING LIFT AND MID LEVEL MOISTURE WILL SUPPORT THE
   DEVELOPMENT OF SCT TSTMS OVER MUCH OF THE NRN ROCKIES THIS
   AFTERNOON. FORECAST SOUNDINGS ALONG WITH RECENT OBSERVED DEWPTS
   SUGGEST THAT MOST CONVECTION WILL BE DRY /ALTHOUGH SOME TRANSITION
   TO WET IS POSSIBLE LATE IN THE PERIOD OVER CENTRAL AND ERN MT/.
   ALONG WITH LITTLE OR NO RAINFALL...STRONG AND ERRATIC WINDS WILL
   ALSO BE POSSIBLE WITH SOME OF THE TSTMS.
   
   ...CRITICAL FIRE WEATHER AREA - MUCH OF THE ERN GREAT BASIN /ERN
   NV...WRN UT...AND SERN ID/...
   
   PRIMARY CONDITIONS: SUSTAINED SWLY WINDS FROM 20-30 MPH...MIN RH
   READINGS FROM 5-15 PERCENT
   
   ALONG THE SRN PERIPHERY OF THE UPPER TROUGH...SWLY WINDS WILL
   INCREASE DURING THE MORNING...BECOMING SUSTAINED OVER 20 MPH DURING
   THE AFTERNOON AHEAD OF A COLD FRONT WHICH WILL EXTEND FROM WRN ID
   INTO CENTRAL NV BY LATE AFTERNOON. THE COMBINATION OF MODERATE WINDS
   ALONG WITH ABOVE NORMAL TEMPERATURES AND LOW RH READINGS LESS THAN
   15 PERCENT WILL CREATE CRITICAL FIRE WEATHER CONDITIONS. IN ADDITION
   TO THE STRONG WINDS...ISOLATED DRY TSTMS WILL BE POSSIBLE OVER ERN
   ID AND FAR NERN NV/FAR NRN UT DURING THE AFTERNOON/EARLY EVENING HRS
   ON THE SRN FRINGES OF UPPER FORCING. WINDS ARE FORECAST TO DECREASE
   TO BELOW CRITICAL LEVELS BY EVENING.
   
   ...NRN PLAINS...
   AHEAD OF THE UPPER TROUGH AND EAST OF A DEEPENING AREA OF SFC LOW
   PRESSURE/LEE TROUGH OVER ERN MT...SLY WINDS WILL INCREASE DURING THE
   PERIOD OVER MUCH OF ND/SD. MOISTURE WILL INCREASE AS WELL /DWPTS
   OVER 55 F/ TENDING TO LIMIT RH READINGS TO ABOVE 25 PERCENT FOR THE
   MOST PART. MARGINAL WINDS /SUSTAINED AROUND 20 MPH/ COMBINED WITH
   THESE MARGINAL RH READINGS WILL PRECLUDE A CRITICAL FIRE WEATHER
   THREAT.

   VALID 091200Z - 101200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR MUCH OF WY...
   
   ...SYNOPSIS...
   A PROGRESSIVE UPPER TROUGH WILL MOVE EWD FROM THE NRN ROCKIES INTO
   THE NRN PLAINS DURING THE PERIOD. ALONG WITH THE PASSAGE OF THIS
   UPPER TROUGH...MODERATE WLY WINDS WILL DEVELOP OVER MUCH OF WY.
   COMBINED WITH LOW RH READINGS...A CRITICAL FIRE WEATHER THREAT WILL
   OCCUR. SCT TSTMS WILL AGAIN FORM AHEAD OF THE UPPER TROUGH OVER THE
   WRN HIGH PLAINS REGION. HOWEVER INCREASING LOW LEVEL MOISTURE WILL
   SUPPORT MOSTLY WET TSTMS. FURTHER SOUTH...ANOTHER DAY OF SCT
   MONSOONAL-TYPE TSTMS WILL OCCUR OVER THE SRN ROCKIES. IN THE WAKE OF
   THE UPPER TROUGH...UPPER RIDGING WILL LEAD TO A MARKED WARMING TREND
   OVER MUCH OF CA. ELSEWHERE...THE UPPER RIDGE WILL REMAIN FIRMLY
   ENTRENCHED OVER THE SRN PLAINS LEADING TO ANOTHER HOT DAY OVER MUCH
   OF NRN TX/OK AND KS. HOWEVER...SLOWLY INCREASING SLY WINDS WILL LEAD
   TO AN INCREASING FIRE DANGER.
   
   ...CRITICAL FIRE WEATHER AREA - MUCH OF WY...
   
   PRIMARY CONDITIONS: SUSTAINED WLY WINDS FROM 20-25 MPH. VERY LOW RH
   READINGS FROM 5-10 PERCENT
   
   TO THE SOUTH OF AN UPPER TROUGH...MODERATE MID LEVEL WINDS WILL
   COMBINE WITH STEEP LOW-MID LEVEL LAPSE RATES TO GENERATE WLY WINDS
   OVER 20 MPH DURING THE AFTERNOON. VERY DRY AIR WITH DWPTS IN THE
   TEENS/20S WILL BE PRESENT TO THE WEST OF A DRYLINE THAT IS
   ANTICIPATED TO BE OVER THE SD BORDER DURING THE AFTERNOON. WARM
   TEMPERATURES IN THE 80S TO LOWER 90S WILL PRODUCE MIN RH READINGS
   FROM 5-10 PERCENT. WITH THE PASSAGE OF A COLD FRONT...WINDS MAY
   REMAIN MODERATE OVER NRN WY INTO THE EVENING HRS.
   
   ...SWRN KS...WRN OK AND THE ERN TX PANHANDLE...
   AS TEMPERATURES WARM ABOVE 100...AN INCREASING SUBSIDENT AIRMASS AND
   VERY DRY SOIL CONDITIONS WILL SUPPORT DEWPTS AGAIN INTO THE 50S AND
   MIN RH READINGS FROM 20-25 PERCENT. IN RESPONSE TO THE UPPER TROUGH
   MOVING ACROSS THE NRN PLAINS...A LOW LEVEL JET IS FORECAST TO EXIST
   ACROSS THE REGION EARLY IN THE PERIOD. A MODERATE PRESSURE GRADIENT
   WILL ALSO SUPPORT SLY WINDS FROM 15-20 MPH DURING THE AFTERNOON.
