   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0338 AM CDT THU SEP 06 2007
   
   VALID 061200Z - 071200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER-LEVEL LOW OVER THE NERN GREAT BASIN WILL ACCELERATE EWD AS
   AN UPSTREAM SHORT WAVE TROUGH OVER SWRN CANADA AMPLIFIES SEWD.
   DOWNSTREAM HEIGHT FALLS WILL AID IN SURFACE CYCLONE INTENSIFICATION
   OVER SD...EVENTUALLY TRACKING NEWD ALONG A QUASI-STATIONARY SW-NE
   ORIENTED FRONTAL ZONE TOWARDS THE UPPER MS RIVER VALLEY BY EARLY
   FRI. SECONDARY LEE CYCLONE WILL BECOME CENTERED OVER ERN CO/WRN KS
   THIS AFTERNOON WITH A SURFACE TROUGH LYING SWWD AND A DRY LINE
   ARCING ACROSS WRN KS THROUGH THE NRN TX PANHANDLE.
   
   ...SWRN KS/WRN OK AND NWRN TX PANHANDLES...
   MODERATELY STRONG SWLY WINDS AND MARGINALLY LOW RH WILL ENHANCE THE
   FIRE WEATHER THREAT GIVEN RECENT DRYNESS. TEMPERATURES WILL BE WELL
   ABOVE-NORMAL THIS AFTERNOON /FROM THE MIDDLE 90S TO AROUND 100/...TO
   THE W OF A DRY LINE EXPECTED TO BE ARCING ROUGHLY FROM GCK TO BGD TO
   CVS AT 06/21Z. INCREASINGLY DEEP MIXING BEHIND THIS BOUNDARY WILL
   PROMOTE SUSTAINED SURFACE WINDS AROUND 20 TO 25 MPH THROUGH MUCH OF
   THE AFTERNOON. EVEN WITH DEW POINTS ONLY DROPPING TO THE UPPER 40S
   TO LOWER 50S...RH VALUES WILL BECOME MARGINALLY LOW /AROUND 20
   PERCENT/. THIS MAY PROVIDE LOCALIZED CRITICAL CONDITIONS FOR A SHORT
   TIME NEAR PEAK HEATING.
   
   ...FAR SERN WY/WRN NEB PANHANDLE...
   RELATIVELY WIDESPREAD WETTING RAINFALL ON WED EVENING THROUGH EARLY
   THIS MORNING SHOULD LARGELY CURTAIL ANY SIGNIFICANT FIRE WEATHER
   CONCERNS THIS AFTERNOON. MODEL GUIDANCE FORECASTS HAVE ALSO BACKED
   OFF ON THE STRENGTH OF W/NWLY WINDS THAT WILL DEVELOP AFTER THE
   PASSAGE OF A SHORT WAVE TROUGH. EVEN WITH DRYING EFFECTS FROM
   DOWNSLOPE AND SUBSIDENCE...THE POTENTIAL FOR RH VALUES TO DROP BELOW
   15 PERCENT APPEARS SLIM.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0410 AM CDT THU SEP 06 2007
   
   VALID 071200Z - 081200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   PROGRESSIVE UPPER-LEVEL PATTERN WILL CONTINUE ACROSS THE NRN CONUS.
   A SHORT WAVE TROUGH OVER THE UPPER MIDWEST ON EARLY FRI WILL LIFT
   RAPIDLY NEWD ACROSS SERN CANADA...WHILE AN UPSTREAM SHORT WAVE WILL
   DIG SEWD FROM SWRN CANADA TOWARDS THE NRN ROCKIES BY FRI EVENING.
   SURFACE LOW ATTENDANT TO THE LATTER WAVE SHOULD TRACK ACROSS CNTRL
   MT WITH A COLD FRONT PUSHING SEWD THROUGH THE PACIFIC NW.
   
   ...ERN SLOPES OF THE CASCADES/WRN COLUMBIA BASIN IN WA..
   NWLY LOW/MID-LEVEL FLOW WILL INCREASE IN RESPONSE TO A POTENT SHORT
   WAVE TROUGH DIGGING TOWARDS THE NRN ROCKIES AND AFTER A COLD FRONT
   PASSAGE FRI MORNING. ALTHOUGH MID/UPPER-LEVEL FLOW SHOULD BECOME
   RATHER STRONG...MODEL FORECAST SOUNDINGS SUGGEST WEAK MID-LEVEL
   LAPSE RATES SHOULD TEND TO MITIGATE MORE SUBSTANTIAL LOW-LEVEL FLOW
   FROM BEING FULLY REALIZED. NEVERTHELESS...SUSTAINED SURFACE WINDS OF
   15 TO 20 MPH SHOULD BECOME FAIRLY WIDESPREAD BY PEAK HEATING. WITH
   TEMPERATURES GENERALLY IN THE MIDDLE 70S TO LOWER 80S...RH VALUES
   WILL LIKELY BECOME MARGINALLY LOW /AROUND 20 PERCENT/.
