   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0402 AM CDT SUN AUG 22 2004
   
   VALID 221200Z - 231200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER TROUGH OVER THE PAC NW AT THE START OF THE PERIOD WILL DIG
   ESEWD INTO THE NRN ROCKIES. IN THE WAKE OF AN ASSOCIATED COLD
   FRONT...SCT PRECIPITATION WILL CONTINUE TO SPREAD EWD...LIMITING ANY
   FIRE WEATHER THREATS FOR MUCH OF THE PAC NW AND NRN ROCKIES REGION.
   AHEAD OF THE FRONT...SWLY WINDS WILL BE MODERATE OVER PORTIONS OF
   THE GREAT BASIN INTO THE CENTRAL ROCKIES. A CORRIDOR OF NEAR
   CRITICAL FIRE WEATHER CONDITIONS WILL EXIST OVER THE NRN/ERN GREAT
   BASIN WHERE MIN RH VALUES WILL BE AROUND 15 PERCENT AND AFTERNOON
   WINDS WILL BE ABOVE 20 MPH. CRITICALLY LOW RH READINGS FROM 10-15
   PERCENT WILL BE COMMON ACROSS UT/SRN NV AND MUCH OF AZ. HOWEVER...IN
   THIS AREA WEAKER WINDS WILL LIMIT ANY FIRE CONCERNS IN THIS REGION.
   
   ...NRN/ERN GREAT BASIN...
   SWLY WINDS WILL INCREASE THROUGH THE MORNING AHEAD OF AN UPPER
   TROUGH/COLD FRONT PROGRESSING SEWD INTO THE PAC NW. SUSTAINED WINDS
   FROM 20-25 MPH WITH GUSTS TO 30 MPH ARE ANTICIPATED. ALONG THE SFC
   THERMAL RIDGE AHEAD OF THE FRONT...ABOVE NORMAL TEMPERATURES CAN BE
   EXPECTED ALONG WITH MINIMUM RH READINGS AROUND 20 PERCENT. THE FRONT
   IS EXPECTED TO REACH A LINE FROM ABOUT SALT LAKE CITY TO TONOPAH BY
   22/12Z...WITH WINDS SHIFTING TO THE NW BEHIND THE FRONT. LACK OF
   LOWER THAN CURRENTLY PROJECTED ABOVE CRITICAL RH READINGS DURING
   PERIOD OF STRONGEST WINDS WILL PRECLUDE A CRITICAL FIRE WEATHER
   THREAT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0404 AM CDT SUN AUG 22 2004
   
   VALID 231200Z - 241200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   INITIAL UPPER TROUGH OVER THE PAC NW ON DAY ONE WILL MOVE NEWD FROM
   THE NRN ROCKIES INTO THE NRN PLAINS THROUGH THE PERIOD...WITH
   ADDITIONAL SHORTWAVE ENERGY MOVING SEWD INTO THE PAC NW. THE RESULT
   WILL BE A BROADENING OF THE UPPER TROUGH OVER THE WEST. SCT
   PRECIPITATION WILL CONTINUE OVER MUCH OF THE NRN ROCKIES/PAC NW IN
   ASSOCIATION WITH BROAD CYCLONIC FLOW. INCREASING MID LEVEL FLOW SWD
   INTO THE SRN GREAT BASIN AND CENTRAL ROCKIES WILL AID IN INCREASING
   SURFACE WINDS OVER THIS REGION. DESPITE NEAR CRITICAL LOW RH
   READINGS IN THE REGION...RECENT PRECIPITATION AND LACK OF HIGHER
   FIRE DANGERS IS ANTICIPATED TO PRECLUDE A CRITICAL FIRE WEATHER
   THREAT.
   
   ...SRN GREAT BASIN INTO THE CENTRAL ROCKIES...
   MID LEVEL WSWLY FLOW WILL INCREASE OVER THE AREA AS AN UPPER TROUGH
   DEEPENS OVER THE WEST. WARM TEMPERATURES WILL BE FOUND AHEAD OF AN
   ASSOCIATED COLD FRONT EXTENDING ROUGHLY FROM CENTRAL NV INTO NRN UT
   ALONG WITH LOW DEWPT TEMPERATURES WILL AID IN MIN RH READINGS FROM
   10-15 PERCENT. SWLY SUSTAINED WINDS FROM 15-20 MPH WITH GUSTS TO 25
   MPH ARE ANTICIPATED DURING THE AFTERNOON/EVENING. RECENT
   PRECIPITATION HAS ALLOWED FOR ONLY MODERATE FIRE DANGERS OVER MOST
   OF THE AREA. IF LATER DATA INDICATES INCREASING FIRE DANGER...THEN
   PORTIONS OF THE AREA MAY NEED TO BE UPGRADED TO A CRITICAL FIRE
   WEATHER OUTLOOK.
