   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0348 AM CDT MON AUG 04 2008
   
   VALID 041200Z - 051200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER-LEVEL HIGH WILL REMAIN CENTERED OVER THE SRN HIGH PLAINS. 
   EXPANSIVE RIDGE AXIS EMANATING NEWD FROM THE HIGH WILL SLOWLY SHIFT
   EWD ACROSS THE GREAT LAKES. AN UPPER-LEVEL TROUGH WILL PERSIST
   ACROSS THE CANADIAN PRAIRIES AND N-CNTRL CONUS. AN EMBEDDED SHORT
   WAVE WILL TRACK FROM THE NRN ROCKIES TOWARDS THE UPPER MIDWEST. IN
   ITS WAKE...RIDGING WILL SLOWLY BUILD NWD ACROSS THE NWRN CONUS.
   
   ...PORTIONS OF SWRN KS...
   S/SWLY WINDS WILL PERSIST S OF A SURFACE TROUGH DRAPED ACROSS THE
   CNTRL HIGH PLAINS. THIS WILL MAINTAIN HOT TEMPERATURES /NEAR 105/
   AND RELATIVELY DRY CONDITIONS /RH VALUES AROUND 15 PERCENT/ DURING
   THE MID TO LATE-AFTERNOON. ALTHOUGH THE LOW-LEVEL JET IS OVERHEAD
   ATTM /40 TO 45 KT PER AREA PROFILERS/...DIURNAL WEAKENING OF THE JET
   ALONG WITH A SLIGHT RELAXING OF THE SURFACE PRESSURE
   GRADIENT...SHOULD RESULT IN MORE MARGINAL SURFACE WINDS COMPARED TO
   PREVIOUS DAYS. NEVERTHELESS...SUSTAINED SPEEDS NEAR 20 MPH WILL LEAD
   TO LOCALIZED/SHORT-DURATION CRITICAL CONDITIONS AT PEAK
   HEATING...MOST LIKELY IN AN AXIS FROM CLARK TO PAWNEE COUNTY.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0451 AM CDT MON AUG 04 2008
   
   VALID 051200Z - 061200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   MID/UPPER-LEVEL SHORT WAVE TROUGH WILL TRACK FROM THE UPPER MIDWEST
   TOWARDS THE ERN GREAT LAKES THROUGH EARLY WED. AN UPSTREAM IMPULSE
   WILL EJECT FROM THE SWRN CANADIAN ROCKIES TO THE NRN PLAINS. AN
   UPPER-LEVEL HIGH WILL SLOWLY DRIFT WWD FROM THE SRN HIGH PLAINS TO
   THE SRN ROCKIES...WITH RIDGE AXIS GRADUALLY BUILDING NWWD OVER THE
   NWRN CONUS.
   
   ...NWRN NV/NERN CA/SERN ORE/SWRN ID...
   MODEL GUIDANCE CONTINUE TO DEPICT MID/UPPER-LEVEL MONSOONAL MOISTURE
   BEING SLOWLY DRAWN NWD ON WRN PERIPHERY OF AMPLIFYING SRN
   ROCKIES/PACIFIC NW RIDGE AXIS. DESPITE AN INCREASE IN MOISTURE ATOP
   A VERY WARM/DRY BOUNDARY LAYER...FORECAST SOUNDINGS SUGGEST
   DESTABILIZATION WILL REMAIN QUITE LIMITED WITH AN OVERALL LACK OF
   APPRECIABLE LARGE-SCALE ASCENT AND RISING HEIGHTS. THE GFS DOES
   INDICATE SOME POTENTIAL FOR WEAK MID-LEVEL BUOYANCY. HOWEVER...THIS
   IS LIKELY IN ASSOCIATION WITH A VORTICITY MAXIMUM THAT APPEARS TO BE
   CONVECTIVELY GENERATED OVER THE SRN CA COASTAL MTNS ON DAY 1. AS
   SUCH...LOW CONFIDENCE EXISTS IN THIS FEATURE ACTUALLY DEVELOPING
   SINCE THIS IS NOT DEPICTED IN EITHER THE NAM/NAMKF/ECMWF. PROSPECTS
   FOR DRY TSTM COVERAGE BEYOND ISOLATED APPEAR SLIM.
