   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0248 AM CDT SUN JUN 22 2008
   
   VALID 221200Z - 231200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR DRY THUNDERSTORMS...
   
   ...SYNOPSIS...
   BREAKDOWN OF THE UPPER RIDGE WILL CONTINUE ACROSS THE NRN ROCKIES
   AND GREAT BASIN THROUGH SUNDAY AS A SERIES OF SHORT WAVE TROUGHS
   SPREAD INLAND AND PRODUCE MODEST HEIGHT FALLS ACROSS THESE AREAS. 
   PACIFIC FRONT WILL CONTINUE TO TRANSLATE INLAND/EWD FROM THE
   INTERIOR NORTHWEST TO MT WITH THE LEADING EDGE OF THE DEEP-LAYER
   FRONTAL ZONE MAKING SLOWER SWD PROGRESS INTO NRN PARTS OF NV AND UT.
   
   DESPITE THE HEIGHT FALLS ACROSS THE GREAT BASIN...ANOTHER HOT AND
   BREEZY /LOCALLY WINDY/ DAY WILL DEVELOP OVER THE REGION WITH
   AFTERNOON HIGH TEMPERATURES REACHING WELL INTO 90S F NORTH AND
   READINGS OF 100F TO 115F OVER SOUTHERN/DESERT AREAS.
   
   ...CRITICAL FIRE WEATHER AREA - ERN NV...UT...ADJACENT AREAS OF
   WY/CO...
   
   PRIMARY CONDITIONS: WIDELY SCATTERED DRY THUNDERSTORMS/HIGH
   TEMPERATURES/LOW RH
   
   ...GREAT BASIN AREA...
   LARGE SCALE ASCENT ALONG AND IN ADVANCE OF THE FRONTAL ZONE WILL AID
   AFTERNOON AND EVENING HIGH-BASED THUNDERSTORM DEVELOPMENT FROM NV
   ACROSS UT AND THE INTERMOUNTAIN WEST. VERY HOT AND WELL-MIXED
   BOUNDARY LAYER WILL RESULT IN CLOUD BASES ABOVE 10 KFT AGL AND LOW
   SUB-CLOUD RH WILL ASSURE RAPID EVAPORATION OF PRECIPITATION. PARTS
   OF THE REGION ARE EXPERIENCING LONG-TERM DROUGHT AND CONDITIONS
   SHOULD BE SUPPORTIVE OF LIGHTNING-INDUCED FIRE STARTS.
   
   HIGH TEMPERATURES...LOW RH...AND SW WINDS OF 10-15 MPH WITH LOCAL
   GUSTS TO 25 MPH WILL ALSO CONTRIBUTE TO FIRE DANGER OVER THE REGION.
   
   ...SERN CA...
   HIGH PRESSURE BUILDING OFF THE CA COAST WILL RESULT IN INCREASING
   ONSHORE FLOW WITH MODERATE SWLY WINDS AGAIN DEVELOPING OVER THE HIGH
   DESERT OF SERN CA. STRONGER WINDS WILL COMBINE WITH VERY HOT
   TEMPERATURES 100-110F AND LOW RH VALUES FOR A FEW HOURS DURING THE
   AFTERNOON. OVERALL DURATION OF CRITICAL CONDITIONS SHOULD REMAIN
   LIMITED TO LESS THAN 4 HOURS WITH SOME RH RECOVERY DURING THE
   EVENING.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0252 AM CDT SUN JUN 22 2008
   
   VALID 231200Z - 241200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   RIDGING WILL CONTINUE TO BE SUPPRESSED ACROSS THE GREAT BASIN AND
   WRN STATES AS MEAN-LAYER ONSHORE FLOW CONTINUES. MINOR DISTURBANCES
   MOVING INLAND FROM THE PACIFIC WILL MAINTAIN A WEAK UPPER TROUGH
   OVER PARTS OF CA/NV. GENERALLY WEAK MID LEVEL FLOW OVER MUCH OF THE
   REGION AND A SLIGHT ABATEMENT TO THE HOTTER CONDITIONS OF LATE
   SHOULD PRECLUDE LARGER CRITICAL FIRE WEATHER AREAS.
   
   DIURNALLY LOW RH AND LOCAL GUSTY WINDS WILL STILL BE POSSIBLE FOR A
   FEW HOURS OVER PARTS OF SRN CA AND THE LOWER CO RIVER VALLEY AND
   HIGH-BASED /DRY/ THUNDERSTORMS COULD STILL PROVOKE A FEW LIGHTNING
   IGNITIONS OVER THE INTERMOUNTAIN WEST. HOWEVER...OVERALL PATTERN
   DOES NOT APPEAR TO WARRANT ANY CRITICAL AREAS ATTM.
