   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0251 AM CDT THU JUN 23 2005
   
   VALID 231200Z - 241200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   MINIMAL CHANGE IS EXPECTED IN LARGE-SCALE UPPER FLOW PATTERN ACROSS
   THE COUNTRY THIS PERIOD. STRONG UPPER RIDGE WILL REMAIN ACROSS THE
   SRN ROCKIES EWD THROUGH THE MID MS AND OH RIVER VALLEYS. MAIN BELT
   OF THE WESTERLIES WILL REMAIN CONFINED TO THE NRN TIER OF THE U.S.. 
   
   A STRONG SHORTWAVE TROUGH OVER ERN WA/NRN ID EARLY THIS MORNING WILL
   TRACK EWD ALONG THE U.S./CANADIAN BORDER REACHING THE ERN DAKOTAS
   AND MANITOBA BY 24/12Z. QUASISTATIONARY UPPER LOW WILL REMAIN OFF
   THE CENTRAL CA COAST...WITH BAND OF 30-35KT 500MB FLOW DOWNWIND OF
   THIS SYSTEM ACROSS SRN CA INTO THE GREAT BASIN. SLY MID-LEVEL FLOW
   COMPONENT WITH AMPLE MOISTURE WILL RESULT IN SCATTERED THUNDERSTORM
   ACTIVITY WITH DAYTIME HEATING ACROSS MUCH OF THE FOUR CORNERS REGION
   NNEWD INTO WY. MAJORITY OF THUNDERSTORMS SHOULD BE WET...
   HOWEVER...ISOLATED DRY THUNDERSTORMS ARE POSSIBLE ON WRN FRINGE OF
   MID-LEVEL MOISTURE PLUME...PRIMARILY ACROSS ERN NV AND WRN UT.
   
   ...SRN CA AND CENTRAL/SRN NV...
   
   MODERATE SLY TO SWLY SURFACE WINDS OF 15-20 MPH WILL DEVELOP THIS
   AFTERNOON ACROSS THE SWRN GREAT BASIN AND INTERIOR SRN CA IN
   RESPONSE TO DEEP VERTICAL MIXING AND MODERATE SWLY MID-LEVEL FLOW. 
   LITTLE CHANGE IS FORECAST IN LOW-LEVEL TEMPERATURE AND HUMIDITY
   CONDITIONS TODAY. EXTREME SURFACE TEMPERATURES...WITH BASIN/VALLEY
   HIGHS OF 100-110F ACROSS SRN NV AND INTERIOR SRN CA WILL YIELD
   MINIMUM RH VALUES OF 5-10 PERCENT. NAM SOUNDINGS SUGGEST SURFACE
   BASED DRY ADIABATIC LAPSE RATES UP TO 12-15 KFT. VERY DRY FINE FUEL
   CONDITIONS WILL ALSO CONTRIBUTE TO WILDFIRE POTENTIAL. ALTHOUGH
   LARGE-SCALE WINDS ARE JUST BELOW CRITICAL CRITERION...LOCALIZED FIRE
   WEATHER PROBLEMS ARE POSSIBLE THIS PERIOD GIVEN EXTREME
   TEMPERATURE/RH VALUES AND FAVORABLY DRY FUEL CONDITIONS.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0330 AM CDT THU JUN 23 2005
   
   VALID 241200Z - 251200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   DURING THE DAY 2 PERIOD...500MB RIDGE AXIS EXTENDING FROM NWRN
   MEXICO NEWD ACROSS THE CENTRAL PLAINS INTO THE MID-ATLANTIC REGION
   WILL REMAIN AS THE CONTROLLING WEATHER FEATURE ACROSS MUCH OF THE
   COUNTRY. STRONG ZONAL FLOW WITH EMBEDDED SHORTWAVE TROUGHS WILL
   PERSIST ACROSS THE NRN ROCKIES EWD TO THE NRN PLAINS. PERSISTENT AND
   BROAD UPPER LOW IN THE ERN PACIFIC...WILL BEGIN TO ACCELERATE EWD
   REACHING THE S-CENTRAL CA COAST BY 25/06Z. MODERATE MID-LEVEL SWLY
   FLOW IN ADVANCE OF THIS TROUGH WILL CONTINUE ACROSS SRN CA INTO SRN
   NV...WITH 500MB WIND SPEEDS OF 35-40 KT. SYNOPTIC PATTERN WILL
   CONTINUE FAVORABLE FOR SEASONABLY HOT AND DRY CONDITIONS WITH
   MODERATE DAYTIME WINDS ACROSS THE WRN GREAT BASIN AND INTERIOR SRN
   CA.
   
   AFTERNOON THUNDERSTORM ACTIVITY SHOULD REMAIN SCATTERED ACROSS THE
   SRN/CENTRAL ROCKIES...WITH ISOLATED ACTIVITY LIKELY NEAR THE SRN
   CASCADES. POTENTIAL FOR DRY THUNDERSTORMS APPEARS LIMITED AT THIS
   TIME.
   
   ...INTERIOR SRN CA AND THE WRN GREAT BASIN...
   
   WITH BAND OF MODERATE SWLY MID-LEVEL FLOW REMAINING ACROSS THE
   DISCUSSION AREA...SURFACE WINDS OF 15-20 MPH SHOULD DEVELOP BY EARLY
   AFTERNOON IN ASSOCIATION WITH DEEP BOUNDARY LAYER MIXING. PROLONGED
   RH VALUES BETWEEN 8-15 PERCENT ARE LIKELY ACROSS LOWER ELEVATION
   AREAS FRIDAY AFTERNOON INTO EARLY EVENING. HIGH TEMPERATURES WILL
   RANGE FROM THE UPPER 80S TO LOW 90S ACROSS CENTRAL NV TO THE LOW
   100S ACROSS SRN NV...FAR SWRN UT...AND INTERIOR SRN CA. COMBINED
   WITH VERY DRY FINE FUELS...FAVORABLE TEMP/RH CONDITIONS SHOULD
   RESULT IN LOCALIZED FIRE WEATHER CONCERNS ACROSS INTERIOR SRN CA AND
   THE WRN GREAT BASIN ON FRIDAY...ESPECIALLY IN AREAS WHERE SURFACE
   WINDS ARE LOCALLY HIGHER DUE TO OROGRAPHIC INFLUENCES.
