   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK

   VALID 101200Z - 111200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   BROAD UPPER TROUGH ACROSS THE NWRN CONUS IS ASSOCIATED WITH A
   SURFACE COLD FRONT EXTENDING FROM FAR NERN MT SWWD ACROSS NWRN WY
   AND THE FAR NRN GREAT BASIN. WITH TIME THIS AFTERNOON...SURFACE
   FRONT WILL MOVE SLOWLY SWD/SEWD ACROSS CENTRAL WY WHILE TRANSLATING
   EWD ACROSS THE DAKOTAS. THIS SYSTEM WILL BRING MUCH COOLER
   TEMPERATURES TO MUCH OF NRN WY...MT...AND THE WRN DAKOTAS.
   
   SOUTH OF THE WESTERLIES...SUBTROPICAL RIDGE WILL BUILD EWD FROM THE
   ERN PACIFIC INTO THE SRN GREAT BASIN AND AZ THIS PERIOD. THERMAL
   RIDGING AT 700MB WILL BE MAINTAINED FROM CENTRAL NM NWD THROUGH
   CO...WITH RIDGE AXIS EXTENDING NEWD ACROSS NEB AND THE ERN DAKOTAS
   THIS AFTERNOON. SEASONABLY HOT AND DRY CONDITIONS WILL BE MAINTAINED
   ACROSS THE CENTRAL AND SRN INTERMOUNTAIN WEST.
   
   ...NERN NV...NRN UT...NWRN CO...AND CENTRAL/SRN WY...
   
   ALONG SRN PERIPHERY OF NWRN CONUS UPPER TROUGH...BAND OF 40-45KT
   500MB FLOW WILL EXTEND ACROSS FAR NRN NV ENEWD ACROSS CENTRAL WY.
   JUST SOUTH OF SFC FRONT...WLY TO SWLY WINDS OF 15-20 MPH WILL
   DEVELOP AT THE SURFACE WITH DAYTIME HEATING/MIXING...WITH
   VALLEY/BASIN TEMPERATURES GENERALLY IN THE MID 80S TO LOW 90S. WITH
   MINIMUM RH VALUES OF 15-20 PERCENT ACROSS THE DISCUSSION AREA...FIRE
   WEATHER CONDITIONS WILL BECOME MARGINALLY CRITICAL DURING THE
   AFTERNOON THROUGH EARLY EVENING HOURS. DRY FUELS WILL ALSO
   CONTRIBUTE TO FIRE WEATHER THREAT...HOWEVER...WIND SPEEDS SHOULD
   REMAIN JUST BELOW CRITICAL LEVELS THROUGH THE FORECAST PERIOD.
   
   ...SRN ROCKIES...
   
   AS SUBTROPICAL RIDGE BUILDS EWD ACROSS THE SWRN CONUS...POTENTIAL
   FOR DRY THUNDERSTORMS SHOULD DECREASE ACROSS SERN AZ AND MUCH OF WRN
   NM TODAY COMPARED TO THE PREVIOUS TWO DAYS WITH ASSOCIATED MID-LEVEL
   SUBSIDENCE. MARGINAL INSTABILITY WILL REMAIN FURTHER EAST ALONG THE
   SACRAMENTO MTNS...WHERE A FEW DRY THUNDERSTORMS ARE POSSIBLE THIS
   AFTERNOON AND EVENING. ANTICIPATED ISOLATED CONVECTIVE COVERAGE WILL
   PRECLUDE A CRITICAL DRY THUNDERSTORM RISK AREA.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0215 AM CDT SUN JUL 10 2005
   
   VALID 111200Z - 121200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   DURING THE DAY 2 PERIOD...MID-LEVEL RIDGE IS FORECAST BY CURRENT
   NAM/GFS SOLUTIONS TO CONTINUE TO BUILD ACROSS THE GREAT BASIN. THIS
   WILL CAUSE STALLED FRONTAL BOUNDARY ACROSS THE NRN GREAT BASIN EWD
   INTO S-CENTRAL WY TO DISSIPATE...WITH A WARMING TREND COMMENCING
   ACROSS MUCH OF THE NWRN CONUS. MAIN BELT OF MID-LEVEL WESTERLIES
   WILL RETREAT NWD TO WA EWD TO MT. WIDESPREAD HOT AND DRY CONDITIONS
   ARE EXPECTED ACROSS THE CENTRAL/SRN INTERMOUNTAIN WEST...WITH
   MINIMUM RH VALUES BELOW 10 PERCENT ACROSS THE CENTRAL/SRN GREAT
   BASIN AND MOST OF THE FOUR CORNERS AREA. HOWEVER...GENERALLY LIGHT
   WINDS LARGELY CONTROLLED BY LOCAL OROGRAPHIC INFLUENCES ARE
   ANTICIPATED GIVEN WEAK SEA-LEVEL PRESSURE GRADIENTS. THE LIGHT WINDS
   WILL PRECLUDE ANY LARGE-SCALE CRITICAL FIRE WEATHER THREAT.
   THUNDERSTORMS ARE GENERALLY NOT EXPECTED ACROSS THE WRN CONUS...WITH
   THE EXCEPTION OF A FEW DRY THUNDERSTORMS ON THE ERN PERIPHERY OF THE
   MID-LEVEL ANTICYCLONE...FROM THE SACRAMENTO MTNS OF S-CENTRAL NM NWD
   THROUGH THE CO FRONT RANGE.
   
   ACROSS THE REMINDER OF THE CONUS...LARGE-SCALE CRITICAL FIRE WEATHER
   CONDITIONS ARE NOT EXPECTED.
