   DAY 1 FIRE WEATHER OUTLOOK

   VALID 191200Z - 201200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF WRN/CNTRL MT...
   
   ...SYNOPSIS...
   AN UPPER-LEVEL TROUGH ALONG THE PACIFIC NW COAST WILL PROGRESS
   INLAND TOWARDS THE NRN ROCKIES. UPPER-LEVEL RIDGE CENTERED OVER THE
   NRN HIGH PLAINS WILL SHIFT EWD TO THE UPPER MS RIVER VALLEY. AT THE
   SURFACE...A COLD FRONT STRETCHING FROM THE ID PANHANDLE TO NRN CA
   WILL MARCH EWD...REACHING THE NRN HIGH PLAINS TO THE CNTRL GREAT
   BASIN BY EARLY WED.
   
   ...CRITICAL FIRE WEATHER AREA - PORTIONS OF WRN/CNTRL MT...
   
   PRIMARY CONDITIONS: SCATTERED DRY THUNDERSTORMS / RECENT DRYNESS
   
   WATER VAPOR IMAGERY CONFIRMS THE PRESENCE OF A SIGNIFICANT IMPULSE
   EMBEDDED WITHIN LARGER-SCALE TROUGH AXIS OVER NRN CA. THE NEWD
   PROGRESSION OF THIS FEATURE SHOULD BE OPTIMALLY TIMED FOR THE PEAK
   OF THE DIURNAL HEATING CYCLE. ASSOCIATED FORCED ASCENT SHOULD AID IN
   SCATTERED TSTM DEVELOPMENT ACROSS THE NRN ROCKIES. ABOVE-NORMAL PW
   VALUES FROM 0.75 TO 1 IN SUGGEST WETTING RAINS SHOULD BE
   PREVALENT...SIMILAR TO THE LOCALLY HEAVY RAIN OBSERVED WITH TSTMS IN
   CNTRL/ERN ORE ON MON EVENING. HOWEVER...FORECAST SOUNDINGS SUGGEST
   THE ERN FRINGE OF THIS MOIST PLUME WILL FAVOR HIGH-BASED TSTMS WITH
   A VERY DEEPLY-MIXED SUB-CLOUD LAYER /SURFACE DEW POINT DEPRESSIONS
   AROUND 60 DEG F/. WITH N/NELY STORM MOTIONS...DRY LIGHTNING
   IGNITIONS ALONG WITH GUSTY/ERRATIC WINDS WILL BE MOST LIKELY ACROSS
   LOWER TERRAIN ADJACENT TO THE NRN ROCKIES.
   
   ...E-CNTRL NV/W-CNTRL UT...
   MODERATE LOW-LEVEL SWLYS SHOULD LEAD TO SHORT-DURATION CRITICAL
   CONDITIONS AHEAD OF AN APPROACHING COLD FRONT. SUSTAINED SURFACE
   WINDS SHOULD BRIEFLY REACH 20 MPH AROUND PEAK HEATING AS RH VALUES
   DIP TO BETWEEN 10 AND 15 PERCENT.
   
   ...SWRN ND...
   A NARROW JUXTAPOSITION OF STRONG WINDS AND LOW RH MAY RESULT IN
   LOCALIZED CRITICAL CONDITIONS THIS AFTERNOON. THE STRONGEST WINDS
   SHOULD DEVELOP ACROSS THE CNTRL DAKOTAS WHERE THE TIGHTEST SURFACE
   PRESSURE GRADIENT WILL LIE. MEANWHILE...BOUNDARY LAYER DRYING WILL
   BE MORE PRONOUNCED FARTHER WEST INTO MT. SUSTAINED SURFACE WINDS AOA
   20 MPH SHOULD LARGELY BE CONFINED TO AREAS WITH RH VALUES AOA 20
   PERCENT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0452 AM CDT TUE AUG 19 2008
   
   VALID 201200Z - 211200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER-LEVEL SHORT WAVE TROUGH OVER THE NRN ROCKIES SHOULD WEAKEN 
   AS IT QUICKLY PROGRESSES NEWD ACROSS THE CANADIAN PRAIRIES. AN
   UPSTREAM UPPER-LEVEL LOW WILL TRACK FROM THE GULF OF AK INTO SRN
   BRITISH COLUMBIA BY EARLY THU. ASSOCIATED MID-LEVEL SPEED MAX WILL
   PENETRATE INLAND ACROSS THE PACIFIC NW.
   
   OVERALL POTENTIAL FOR CRITICAL FIRE WEATHER APPEARS LOW. STRONG
   WINDS WILL BE PREVALENT ACROSS THE NRN PLAINS AND PACIFIC
   NW...ALBEIT WITH MODERATE TO HIGH RH. WHERE LOW RH WILL BE PERVASIVE
   ACROSS THE INTERIOR SOUTHWEST TO THE ERN GREAT BASIN...LIGHT TO
   MODERATE WINDS WILL LIKELY PREVAIL.
