   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0405 AM CDT FRI SEP 15 2006
   
   VALID 151200Z - 161200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR A PORTION OF THE GREAT BASIN...
   
   ...SYNOPSIS...
   A STRONG UPPER TROUGH WILL DIG SEWD INTO THE GREAT BASIN TODAY.
   MODERATE SWLY WINDS WILL DEVELOP OVER THE SRN GREAT BASIN AHEAD OF A
   COLD FRONT...WITH MODERATE NWLY WINDS BEHIND THE COLD FRONT OVER
   PORTIONS OF CENTRAL NV AND THE ERN SLOPES OF THE SIERRA NEVADA MTNS.
   THE COMBINATION OF THESE WINDS AND LOW RH READINGS WILL SUPPORT
   ANOTHER CRITICAL FIRE WEATHER DAY IN THIS AREA. A BROAD ZONE OF
   MODERATE SWLY WINDS WILL DEVELOP OVER MUCH OF THE SRN/CENTRAL
   ROCKIES AND HIGH PLAINS /TO THE WEST OF THE LEE TROUGH/. HOWEVER A
   COMBINATION OF MARGINAL RH READINGS AND/OR LONG TERM MOIST SPELL
   WILL PRECLUDE ANY CRITICAL FIRE WEATHER THREAT IN THIS REGION. SLY
   WINDS WILL REMAIN STRONG OVER THE LOWER SRN/CENTRAL PLAINS
   REGION...BUT MOISTURE RETURN SHOULD BE SUFFICIENT TO OFFSET THE
   WINDS AND ALSO PRECLUDE A CRITICAL FIRE WEATHER THREAT.
   
   ...CRITICAL FIRE WEATHER AREA - SRN/CENTRAL NV...SERN CA...FAR NWRN
   AZ...
   
   PRIMARY CONDITIONS: SUSTAINED SWLY-NWLY WINDS FROM 20-25
   MPH...FRONTAL PASSAGE...LOW RH READINGS AROUND 15 PERCENT
   
   AHEAD OF A STRONG UPPER LOW/TROUGH DIGGING SEWD THROUGH THE PAC NW
   EARLY THIS MORNING...A COLD FRONT WILL MOVE SLOWLY SWD THROUGH THE
   GREAT BASIN. AHEAD OF THE FRONT...SWLY WINDS WILL AVERAGE 20-25 MPH
   WITH GUSTS UP TO 35 MPH FROM SERN CA INTO SRN NV/FAR NWRN AZ.
   SEASONABLY DRY AIR WITH DEWPTS IN THE 20S/30S WITH TEMPERATURES IN
   THE 70S/80S WILL SUPPORT MIN RH READINGS AROUND 15 PERCENT. BEHIND
   THE COLD FRONT...WINDS WILL BE WNWLY AND REMAIN MODERATE WITH GUSTS
   UP TO 40 MPH. DESPITE COOLER TEMPERATURES BEHIND THE FRONT...MUCH
   DRIER AIR WITH DEWPTS IN THE SINGLE DIGITS/TEENS WILL SUPPORT MIN RH
   READINGS FROM 10-15 PERCENT.
   
   ...AZ/NM AND SRN UT...
   SWLY WINDS FROM 20-25 MPH WITH GUSTS OVER 35 MPH WILL BE POSSIBLE
   OVER MUCH OF FOUR CORNER REGION TODAY. ALTHOUGH PORTIONS OF THE AREA
   WILL SEE MIN RH READINGS NEAR 15 PERCENT...THE MAJORITY OF THE AREA
   WILL SEE RH READINGS IN THE 20-25 PERCENT RANGE. ALONG WITH
   RECENT/LONG TERM WET CONDITIONS NO CRITICAL FIRE WEATHER CONDITIONS
   ARE EXPECTED.
   
   ...CENTRAL HIGH PLAINS...
   SSWLY WINDS FROM 20-25 MPH WILL OCCUR TODAY AS A COMBINATION OF
   INCREASING MID LEVEL FLOW...STEEP LOW/MID LEVEL LAPSE RATES AND
   FALLING SFC PRESSURES OCCUR ALONG THE LEE TROUGH. WARM TEMPERATURES
   IN THE 80S AND DEWPTS IN THE 40S WILL PRODUCE MIN RH READINGS FROM
   20-25 PERCENT. LACK OF LOW READINGS WILL PRECLUDE A CRITICAL FIRE
   WEATHER THREAT.
   
   ...ARKLATEX/SERN OK...
   MOISTURE RETURN WILL BE LIMITED OVER THE AREA TODAY AS SFC RIDGING
   REMAINS OVER THE LOWER MS VALLEY. HOWEVER...PRESSURE FALLS OVER THE
   HIGHER PLAINS WILL LEAD TO INCREASING SSELY WINDS /10-15 MPH/.
   DEWPTS IN THE 50S AND TEMPERATURES NEAR 90 WILL SUPPORT MIN RH
   READINGS AROUND 25 PERCENT AND VERY HIGH FIRE DANGER.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0407 AM CDT FRI SEP 15 2006
   
   VALID 161200Z - 171200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   THE UPPER TROUGH OVER THE WEST WILL MOVE SLOWLY EWD ACROSS THE
   ROCKIES TOMORROW. MODERATE SWLY WINDS WILL REMAIN OVER MUCH OF THE
   SRN ROCKIES REGION AND SRN/CENTRAL HIGH PLAINS SUPPORTING NEAR
   CRITICAL FIRE WEATHER CONDITIONS. FURTHER WEST...SFC HIGH PRESSURE
   WILL BUILD SWD INTO THE GREAT BASIN IN THE WAKE OF THE UPPER TROUGH.
   INCREASING NLY WINDS WILL DEVELOP DURING THE AFTERNOON OVER THE
   INTERIOR VALLEYS...WITH THE FLOW BECOMING MORE OFFSHORE LATE IN THE
   PERIOD. A BROAD AREA OF HIGH PRESSURE WILL REMAIN IN CONTROL OVER
   MUCH OF THE COUNTRY EAST OF THE MS RIVER.
   
   ...SRN/CENTRAL HIGH PLAINS AND SRN ROCKIES...
   SWLY WINDS FROM 20-25 MPH WITH GUSTS OVER 30 MPH WILL DEVELOP EARLY
   IN THE PERIOD OVER A BROAD AREA OF THE SRN/CENTRAL HIGH PLAINS AND
   SRN ROCKIES TO THE WEST OF A DRYLINE /LOCATED FROM WRN NEB SWD INTO
   THE TX PANHANDLE/ AND SOUTH OF A COLD FRONT LOCATED OVER ERN WY/SD.
   WARM TEMPERATURES IN THE 80S IN LOWER ELEVATIONS AND LOW DEWPTS IN
   THE 30S/40S WILL SUPPORT MIN RH READINGS FROM 15-25 PERCENT. A
   COMBINATION OF MARGINALLY LOW RH READINGS AND RECENT RAINFALL OVER
   SRN PORTIONS OF THE AREA WILL PRECLUDE A CRITICAL OUTLOOK.
   
   ...CENTRAL/SRN CA...
   EARLY IN THE PERIOD...HIGH PRESSURE SITUATED OVER ORE WILL SUPPORT A
   NLY FLOW OF DRY/SUBSIDENT AIR THROUGH THE SACRAMENTO/SAN JOAQUIN
   VALLEYS. AFTERNOON RH READINGS IN THESE AREAS WILL AVERAGE FROM
   15-20 PERCENT. LACK OF A STRONG N-S GRADIENT SHOULD KEEP SUSTAINED
   WINDS BELOW 20 MPH. AS THE AREA OF HIGH PRESSURE MOVES SEWD INTO THE
   GREAT BASIN OVERNIGHT...SFC WINDS WILL BECOME MORE NELY. A NOCTURNAL
   INCREASE IN THE WINDS ARE EXPECTED MAINLY OVER HIGHER ELEVATIONS
   RESULTING IN POOR RH RECOVERY. HOWEVER GIVEN ONLY A WEAK-MODERATE
   PRESSURE GRADIENT...SUSTAINED WINDS ARE EXPECTED TO REMAIN LESS THAN
   25 MPH PRECLUDING A CRITICAL FIRE WEATHER THREAT.
