   VALID 061200Z - 071200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A STRONG UPPER RIDGE WILL REMAIN OVER THE WRN CONUS WITH A WEAKENING
   TROUGH ACROSS THE EAST. SCATTERED THUNDERSTORMS WILL AGAIN BE LIKELY
   ACROSS THE FOUR CORNERS STATES WITH A MIXTURE OF DRY AND WET STORMS
   OVER THE ERN GREAT BASIN. ANOTHER AREA OF DRY STORMS WILL EXIST
   ACROSS CENTRAL OREGON...AIDED BY A WEAK UPPER SHORT WAVE TROUGH AND
   INCREASED SURFACE CONVERGENCE. A MDT TO HIGH HAINES INDEX WILL EXIST
   OVER MUCH OF CA...THE GREAT BASIN...PACIFIC NW AS WELL AS MT AND WY.
   THUS DESPITE WEAK WINDS...POTENTIAL WILL EXIST FOR AFTERNOON PLUME
   DOMINATED FIRES.
   
   TO THE EAST...HIGH PRESSURE WILL SETTLE INTO THE PLAINS STATES AND
   MS VALLEY REGION...WITH DRY CONDITIONS PREVAILING.
   
   ...CENTRAL OREGON INTO CENTRAL ID AND SWRN MT...
   ISOLATED DRY THUNDERSTORMS ARE LIKELY TO DEVELOP ACROSS THE HIGH
   TERRAIN OF E CENTRAL OREGON. GIVEN VERY LOW SURFACE RH OF 10-15
   PERCENT AND VERY DRY FUELS...ANY STRIKES WILL HAVE A HIGH
   PROBABILITY OF FIRE IGNITION. IN ADDITION...WINDS WILL INCREASE TO
   10-15 MPH BY LATE AFTERNOON FROM CENTRAL WA INTO OREGON...FURTHER
   ENHANCING FIRE THREAT.
   
   FARTHER E INTO ID AND SWRN MT...A FEW DRY STORMS WILL BE LIKELY AS
   WELL WITH LIGHT NELY UPSLOPE FLOW AND LOW SURFACE RH. COVERAGE WILL
   NOT BE PARTICULARLY HIGH...BUT ANY STRIKES MAY CAUSE FIRE STARTS.
   
   ...E CNTRL AND SOUTH TX...
   A RELATIVELY DRY AIR MASS WILL BE IN PLACE TODAY WITH RH DIPPING
   INTO THE 25-35 PERCENT RANGE. WINDS WILL BE FAIRLY LIGHT OUT OF THE
   N AT AROUND 10 MPH...BUT MUCH OF THIS AREA REMAINS IN EXTREME
   DROUGHT...THUS A MARGINAL FIRE THREAT WILL EXIST DURING THE PEAK
   HEATING HOURS.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0504 AM CDT WED SEP 06 2006
   
   VALID 071200Z - 081200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   UPPER RIDGE OVER THE WRN STATES WILL BREAK DOWN A BIT AS A WEAK
   UPPER SHORTWAVE TROUGH MOVES INTO THE GREAT BASIN. THIS WILL ENHANCE
   THE THREAT OF THUNDERSTORMS...BUT MOST OF THEM ARE EXPECTED TO BE
   WET. TO THE W AND S OF THIS SHORTWAVE...A VERY HOT AND DRY AIR MASS
   WILL EXIST...WITH A HIGH HAINES INDEX SPREADING INTO SRN CA.
   
   TO THE NE...A STRONG UPPER TROUGH WILL SWING SWD ACROSS ONTARIO
   CANADA...WITH SURFACE TROUGH/COLD FRONT STRETCHING FROM NRN MN INTO
   CENTRAL SD. BEHIND THIS FRONT...HIGH PRESSURE WILL SURGE LATE IN THE
   DAY. THIS WILL INCREASE WIND SPEEDS INTO ERN MT AND NERN WY.
   
   HIGH PRESSURE WILL BE CENTERED FROM THE MID MS VALLEY INTO THE OH
   VALLEY...WHERE IT WILL BE DRY WITH LIGHT WIND. THE DRY AIR WILL
   REMAIN FARTHER W INTO TX AS WELL...WHERE VERY LOW RH WILL RESIDE.
   
   ...MUCH OF CNTRL AND ERN NV...
   NUMEROUS THUNDERSTORMS ARE EXPECTED TO DEVELOP BY LATE
   AFTERNOON/EARLY EVENING AHEAD OF A WEAK UPPER LEVEL SHORTWAVE
   TROUGH. THE LIGHTNING WILL LIKELY PEAK BETWEEN 21-03Z...AND STORMS
   WILL CONTAIN GUSTY WINDS. IT APPEARS AT THIS TIME THAT THE MAJORITY
   OF THE STORMS WILL BE WET...ALTHOUGH THEY WILL BECOME PROGRESSIVELY
   DRIER WITH WESTWARD EXTEND...CLOSER TO THE DRIEST AIR.
   
   ...SRN CA INTO SWRN NV...
   A BELT OF ENHANCED MID/UPPER LEVEL FLOW WILL EXIST ON SRN EDGE OF
   UPPER SHORTWAVE TROUGH...AND THIS WILL HELP A VERY HOT AND DRY AIR
   MASS SURGE EWD ACROSS THE REMAINDER OF SRN CA. THE HAINES INDEX WILL
   RISE INTO THE HIGH CATEGORY...WITH GUSTY WLY WINDS OF 15-20 MPH.
   THIS...COMBINED WITH VERY LOW RH OF 10-15 PERCENT WILL INCREASE FIRE
   DANGER COMPARED TO PREVIOUS FEW DAYS.
   
   ...ERN MT INTO NERN WY AND FAR NWRN SD...
   HIGH PRESSURE WILL SURGE SWD LATE IN THE DAY OUT OF CANADA...WITH
   NLY WINDS INCREASING TO AROUND 15 MPH WITH HIGHER GUSTS. RH WILL
   REMAIN LOW AND NEAR 15 PERCENT AT PEAK HEATING OVER ERN MT AND NERN
   WY...AND FROM 20-25 PERCENT CENTRAL DAKOTAS. COMBINATION OF LITTLE
   RECENT RAIN ALONG WITH MARGINALLY STRONG WINDS AND LOW RH WILL
   PRODUCE NEAR CRITICAL FIRE CONDITIONS BY LATE AFTERNOON.
