   ...SYNOPSIS...
   UPPER TROUGH...WHICH IS APPROACHING WRN ORE EARLY THIS
   MORNING...WILL MOVE EAST TODAY AND TONIGHT AND BE LOCATED ACROSS WRN
   WA/WRN ORE BY EARLY SUNDAY. THIS TROUGH WILL BE ACCOMPANIED BY A
   MID-LEVEL JET STREAK IN EXCESS OF 50 KT...WHICH WILL AFFECT PORTIONS
   OF THE SOUTHWEST/GREAT BASIN THROUGH TONIGHT. ELSEWHERE...EXPANSIVE
   RIDGE WILL PERSIST ACROSS MUCH OF THE WRN AND CNTRL CONUS WITH UPPER

   PERCENT/VERY HIGH TO EXTREME FIRE DANGER CLASS VALUES/ABOVE NORMAL
   TEMPS
   
   MID LEVEL WINDS WITHIN THE 700-500MB LAYER WILL INCREASE TO 30-55 KT
   TODAY...AND THIS WILL SUPPORT STRONG WINDS AT THE SFC DUE TO NEAR
   DRY-ADIABATIC LAPSE RATES. FORECAST SOUNDINGS SUGGEST MIXING HEIGHTS
   WILL BE JUST ABOVE 500 MB...WITH VERY LOW SFC DEWPOINTS. WITH MAX
   TEMPS RISING INTO THE 80S AND 90S...MINIMUM RH VALUES WILL EASILY
   FALL INTO THE SINGLE DIGITS. LATEST FIRE DANGER CLASS OBSERVATIONS
   INDICATE VALUES IN THE VERY HIGH TO EXTREME RANGE. CRITICAL FIRE
   WEATHER CONDITIONS ARE EXPECTED TO DEVELOP TODAY...AND COULD POSE A
   RISK IF IGNITIONS OCCUR.
   
   ...NRN ROCKIES THROUGH HIGH PLAINS...
   BREEZY AND WARM CONDITIONS ARE FORECAST TODAY...WITH RELATIVELY LOW
   HUMIDITY...ALTHOUGH VALUES SHOULD RANGE FROM 10-20 PERCENT. ISOLD
   CONVECTION WILL LIKELY DEVELOP...BUT IT MAY BE TIED TO THE HIGHER
   ELEVATIONS OF CNTRL ID/NW WY. STRONG WIND GUSTS MAY OCCUR WITH
   COLLAPSING DOWNDRAFTS. ALTHOUGH WINDS SHOULD BE STRONGER THAN
   FRIDAY...THEIR OVERALL MAGNITUDE SHOULD REMAIN BELOW CRITICAL
   THRESHOLDS.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0446 AM CDT SAT MAY 12 2007
   
   VALID 131200Z - 141200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   UPPER RIDGE WILL SHIFT EAST ON SUNDAY...IN RESPONSE TO THE ADVANCE
   OF UPPER TROUGH IN THE NORTHWEST. CONTINUED ABOVE NORMAL
   TEMPERATURES ARE EXPECTED ACROSS THE SOUTHWEST AND PLAINS STATES.
   SFC PATTERN WILL FEATURE MAIN SYNOPTIC LOW ACROSS SD...WITH WARM
   FRONT LIFTING NORTH INTO CNTRL MN AND WELL-DEFINED LEE TROUGH.
   STRONG SFC WINDS WILL BE FOUND ACROSS THE CNTRL/NRN PLAINS
   ASSOCIATED WITH PRESSURE GRADIENT. HOWEVER DUE TO THE SOUTHERLY
   WINDS...MINIMUM RH VALUES WILL LIKELY BE ABOVE CRITICAL VALUES IN
   THE PLAINS EVEN WITH HIGH TEMPS EXCEEDING 90 DEGREES. CRITICAL FIRE
   CONDITIONS ARE POSSIBLE ACROSS PORTIONS OF THE SOUTHWEST DUE TO
   STRONG WINDS/LOW HUMIDITY AND DRY FUELS.
   
   ...SW UT/NW AZ...
   SIMILAR WEATHER CONDITIONS ARE EXPECTED ON SUNDAY RELATIVE TO
   SATURDAY...WITH GUSTY WINDS/LOW HUMIDITY AND ABOVE NORMAL TEMPS
   PERSISTING. SUSTAINED WINDS MAY NOT BE AS STRONG ON SUNDAY HOWEVER.
   MUCH OF THE AREA CONTINUES TO REPORT SEVERE TO EXTREME LONG TERM
   DROUGHT...AND THIS TYPE OF PATTERN WILL SERVE TO FURTHER DRY FUELS.
