   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0400 AM CDT THU AUG 31 2006
   
   VALID 311200Z - 011200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER TROUGH OVER THE NRN ROCKIES WILL SLOWLY MOVE EWD TODAY.
   AHEAD OF THIS TROUGH A SFC COLD FRONT WILL MOVE SWD THROUGH THE NRN
   HIGH PLAINS/CENTRAL ROCKIES. IN THE WAKE OF THE COLD FRONT...MUCH
   COOLER TEMPERATURES AND HIGHER RH READINGS WILL OFFSET MODERATE NWLY
   WINDS TO PRECLUDE ANY CRITICAL FIRE WEATHER THREATS. WELL BEHIND THE
   FRONT A LARGE AREA OF SFC HIGH PRESSURE WILL DEVELOP EWD THROUGH THE
   PAC NW INTO THE NRN ROCKIES. WEST OF THIS HIGH A THERMAL TROUGH WILL
   DEVELOP INTO THE COASTAL SECTIONS OF WA/ORE AND FAR NRN CA LATER
   TODAY/TONIGHT. THIS WILL SUPPORT A EAST WIND EVENT OVER THIS AREA
   AND NEAR CRITICAL FIRE WEATHER CONDITIONS. ELSEWHERE ACROSS THE
   NATION...SLY WINDS WILL RETURN TO THE SRN/CENTRAL PLAINS AHEAD OF A
   LOW PRESSURE AREA OVER ERN CO. LOW RH READINGS WILL SUPPORT HIGH
   FIRE DANGER IN SRN/CENTRAL TX. VERY LOW RH READINGS FROM 5-10
   PERCENT WILL BE PREVALENT OVER PORTIONS OF INTERIOR CA AND THE GREAT
   BASIN.
   
   ...CENTRAL/SRN TX...
   LOW RH READINGS WILL BE PREVALENT OVER MUCH OF CENTRAL/ERN TX IN THE
   WAKE OF YESTERDAY/S COLD FRONT. LONG TERM DROUGHT CONDITIONS EXIST
   OVER THE AREA...BUT SUSTAINED WINDS SHOULD REMAIN LESS THAN 10 MPH
   PRECLUDING A CRITICAL FIRE WEATHER THREAT. 
   
   ...WRN WA/ORE...
   AS HIGH PRESSURE DEVELOPS EWD INTO THE INTERIOR PORTIONS OF THE
   REGION TODAY AND UPPER RIDGING DEVELOPS NWD...A THERMAL TROUGH WILL
   MOVE TOWARDS THE COAST THROUGH THE PERIOD. TEMPERATURES WILL BEGIN
   TO WARM TODAY...BUT MIN RH READINGS SHOULD NOT FALL MUCH BEL0W 30
   PERCENT. RH RECOVERY OVERNIGHT HOWEVER WILL BE POOR...ESPECIALLY
   OVER HIGHER ELEVATIONS AS ELY WINDS INCREASE. LACK OF STRONGER
   PRESSURE GRADIENT FOR MOST OF THE PERIOD /SUSTAINED WINDS AROUND 20
   MPH OVER HIGHER TERRAIN AND THROUGH THE COLUMBIA RIVER GORGE/ LATE
   TONIGHT AND MODESTLY LOW RH READINGS DURING THE DAY TODAY WILL LIMIT
   A CRITICAL FIRE WEATHER THREAT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0401 AM CDT THU AUG 31 2006
   
   VALID 011200Z - 021200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A STRONG COLD FRONT WILL MOVE SWD THROUGH THE CENTRAL PLAINS DURING
   THE DAY TOMORROW. IN THE WAKE OF THE FRONT...MODERATE NNWLY WINDS
   WILL BRING IN MUCH COOLER TEMPERATURES AND HIGHER RH READINGS TO THE
   REGION. FURTHER WEST...UPPER RIDGING WILL DEVELOP NWD THROUGH THE
   PAC NW. AT THE SFC...A THERMAL TROUGH WILL REMAIN NEAR THE COAST
   SUPPORTING AN OFFSHORE FLOW PATTERN AND WELL ABOVE NORMAL
   TEMPERATURES TO MUCH OF WRN WA/ORE. MODERATE ELY WINDS EARLY IN THE
   PERIOD WILL DIMINISH DURING THE DAY...WITH REDEVELOPMENT OVERNIGHT
   EXPECTED TO BE WEAKER THUS LIMITING A CRITICAL FIRE WEATHER THREAT.
   LOW RH READINGS WILL BE COMMONPLACE ACROSS THE REMAINDER OF WA/ORE
   SWD INTO CA AND THE GREAT BASIN.
   
   ...WRN WA/ORE...
   SUSTAINED ELY WINDS FROM 15-25 MPH WITH GUSTS OVER 35 MPH WILL BE
   POSSIBLE EARLY IN THE PERIOD OVER THE HIGHER TERRAIN AND THROUGH THE
   COLUMBIA RIVER GORGE. SUSTAINED ELY WINDS WILL DECREASE TO LESS THAN
   20 MPH OVER MOST OF THE AREA DURING PEAK HEATING WHEN MIN RH
   READINGS FROM 15-25 PERCENT ARE EXPECTED AWAY FROM THE IMMEDIATE
   COAST. AS THE SFC HIGH CONTINUES TO MOVE EWD INTO THE NRN
   ROCKIES...THE PRESSURE GRADIENT SHOULD WEAKEN SUFFICIENTLY TOMORROW
   NIGHT THAT OFFSHORE WINDS SHOULD REMAIN LESS THAN 20 MPH FOR MOST OF
   THE AREA PRECLUDING A CRITICAL FIRE WEATHER THREAT... DESPITE POOR
   RH RECOVERY.
   
   ...CENTRAL/SRN TX...
   LITTLE TO NO SENSIBLE MOISTURE INCREASE IS EXPECTED OVER MOST OF THE
   AREA AS SLY FLOW REMAINS WEAK AND LARGE SCALE SUBSIDENCE EXISTS.
   WARMING TEMPERATURES IN THE MID/UPPER 90S AND DEWPTS IN THE 55-60
   DEG F RANGE WILL PRODUCE MIN RH READINGS IN THE 20-30 PERCENT RANGE.
