   LARGE UPPER LEVEL LOW PRESSURE SYSTEM WILL APPROACH THE PACIFIC
   NORTHWEST COAST TODAY. MID LEVEL WINDS WILL INCREASE TO 60-70 KT
   MAINLY ACROSS ERN ORE/ID/WRN MT AHEAD OF MAIN TROUGH AXIS. AT THE
   SFC...PRIMARY LOW PRESSURE CENTER WILL DEEPEN AS IT MOVES EWD ACROSS
   NERN MT INTO NW ND BY EVENING. A SECONDARY LOW WILL DEVELOP JUST
   WEST OF SLC...AND COLD FRONT IS EXPECTED TO EXTEND FROM NERN WY
   THROUGH CNTRL NV BY LATE AFTN. AHEAD OF THIS BOUNDARY...GUSTY S/SW
   WINDS WILL DEVELOP...CONTRIBUTING TO CRITICAL FIRE CONDITIONS ACROSS

   PRIMARY CONDITIONS: SUSTAINED WINDS 15-25 MPH WITH HIGHER GUSTS/MIN
   RH VALUES BELOW 10 PERCENT/MAX TEMPS 80S TO LOWER 100S/DRY FUELS
   
   WINDS WILL INCREASE BY LATE MORNING/AFTN AHEAD OF COLD FRONT
   APPROACHING FROM ID. THE STRONGEST WINDS WILL LIKELY BE OVER
   NV...WHERE SUSTAINED SPEEDS OF 20-25 MPH ARE LIKELY WITH HIGHER
   GUSTS. ELSEWHERE...WINDS WILL BE SLIGHTLY LESS BUT WITH FREQUENT
   GUSTS. TEMPS WILL RANGE FROM THE MID/UPPER 80S TO 90S FOR MOST
   LOCATIONS. A FEW AREAS ACROSS SRN NV AND SERN CA WILL SEE TEMPS RISE
   ABOVE 100 DEGREES. ACROSS THE ENTIRE AREA...MINIMUM RH VALUES WILL
   RANGE FROM 5-10 PERCENT. LATEST FIRE DANGER CLASS OBSERVATIONS ARE
   SHOWING VERY HIGH TO EXTREME VALUES SO A PERIOD OF CRITICAL

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0336 AM CDT SAT JUN 23 2007
   
   VALID 241200Z - 251200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR SW INTO CNTRL WY/SRN NV/UT/WRN
   CO/NW AZ...
   
   ...SYNOPSIS...
   STRONG SWLY FLOW AT MID LEVELS WILL PERSIST ON SUNDAY ACROSS THE
   NORTHWEST/NRN ROCKIES AND GREAT BASIN AHEAD OF UPPER TROUGH. MAIN
   TROUGH AXIS WILL BEGIN MOVING INTO WRN ORE/WA BY SUNDAY EVENING AS
   LARGE MID LEVEL LOW PRESSURE DEEPENS OVER THE SRN PLAINS. SFC FRONT
   WILL EXTEND FROM NRN MN TO WRN SD TO NW UT AND INTO CNTRL NV. SOUTH
   OF THIS BOUNDARY...GUSTY SWLY WINDS AND LOW HUMIDITY VALUES WILL
   AGAIN RESULT IN CRITICAL FIRE CONDITIONS. GUSTY W/NW WINDS NORTH OF
   THE BOUNDARY WILL RESULT IN AN INCREASED FIRE THREAT...ALTHOUGH
   TEMPERATURES ACROSS NRN NV/SRN ID WILL BE SEVERAL DEGREES COOLER
   THAN ON SATURDAY.
   
   ...CRITICAL FIRE WEATHER AREA - SW INTO CNTRL WY/SRN NV/UT/WRN CO/NW
   AZ...
   
   PRIMARY CONDITIONS: SUSTAINED WINDS 15-25 MPH WITH HIGHER GUSTS/MIN
   RH VALUES LESS THAN 15 PERCENT/DRY FUELS
   
   BECAUSE MUCH OF THE CRITICAL AREA WILL INITIALLY BE SOUTH OF THE
   COLD FRONT ON SUNDAY...HOT AND WINDY CONDITIONS WILL PERSIST ACROSS
   SRN NV/MUCH OF UT AND NW AZ. IN ADDITION...WINDIER CONDITIONS WILL
   DEVELOP ACROSS WY AND WRN CO. HIGH TEMPS WILL RANGE FROM THE UPPER
   80S AND 90S WITH A FEW LOCATIONS ABOVE 100 DEGREES...AS MINIMUM RH
   VALUES DIP BELOW 10 PERCENT. MUCH OF THE AREA CONTINUES TO SUFFER
   FROM MODERATE TO EXTREME LONG TERM DROUGHT. NO TSTMS ARE FORECAST
   FOR THE AREA...SO THE GREATEST FIRE WEATHER THREAT WILL BE FROM WIND
   DRIVEN FIRES...IF NEW IGNITIONS OCCUR.
