   VALID 031200Z - 041200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR CENTRAL AND ERN ID / PORTIONS OF
   SWRN MT AND NWRN WY...
   
   ...SYNOPSIS...
   UPPER RIDGE WILL BE SITUATED OVER THE CENTRAL U.S. WITH LONG WAVE
   TROUGHS OVER BRITISH COLUMBIA AND NEW ENGLAND. STRONG GRADIENT
   BETWEEN THIS RIDGE AND THE TROUGH OVER BRITISH COLUMBIA WILL CAUSE
   INCREASED WIND SPEEDS INTO ID AND MT WHERE IT WILL REMAIN WARM AND
   DRY AHEAD OF A COLD FRONT. THIS FRONT WILL STRETCH FROM WRN MT INTO
   NRN ID THIS AFTERNOON AND WILL BE NEARLY STATIONARY. FARTHER
   S...WEAKER WINDS WILL OCCUR OVER THE GREAT BASIN BUT IT WILL BE WARM
   AND DRY.
   
   FARTHER E...HIGH PRESSURE AT THE SURFACE WILL CAUSE WARM AND DRY
   CONDITIONS OVER MUCH OF THE MS VALLEY.
   
   ...CRITICAL FIRE WEATHER AREA 1 - CENTRAL AND ERN ID / PORTIONS OF
   SWRN MT AND NWRN WY...
   
   PRIMARY CONDITIONS: MODERATE SWLY WINDS / LOW RH / VERY DRY FUELS /
   MDT TO HIGH HAINES
   
   WARM AND WINDY CONDITIONS WILL DEVELOP TODAY AHEAD OF A WEAK COLD
   FRONT...AS UPPER RIDGE SLOWLY BREAKS DOWN. SUSTAINED SWLY WINDS OF
   15-20 MPH WILL OCCUR...WITH HIGHEST GUSTS OF 20-30 MPH LIKELY DURING
   THE AFTERNOON HOURS. HIGH TEMPERATURES WILL AVERAGE 85-90 F...AND
   WILL IN TURN CAUSE MIN RH VALUES OF 15-20 PERCENT. GIVEN WARM AND
   DRY LOW LEVEL AIR MASS BENEATH RELATIVELY COOL AIR ALOFT...LAPSE
   RATES WILL BE STEEP WITH TURBULENT FLOW AND MDT TO HIGH HAINES.
   
   RH RECOVERY WILL BE GOOD OVERNIGHT WITH COOL TEMPERATURES IN THE 40S
   BY SUNRISE.
   
   ...MOJAVE DESERT / GREAT BASIN...
   SUSTAINED WIND SPEEDS AROUND 15 MPH ARE EXPECTED ACROSS THE AREA BY
   AFTERNOON...WITH HIGHER GUSTS OF 20-25 MPH. MIN RH VALUES WILL RANGE
   FROM 10-15 PERCENT OVER CA AND CENTRAL AND WRN NV TO 15-20 PERCENT
   INTO WRN UT.
   
   ...ARKLATEX AREA...
   WITH HIGH PRESSURE IN PLACE...RH LEVELS WILL DROP TO NEAR 30 PERCENT
   BY LATE AFTERNOON. WINDS WILL AVERAGE NEAR 10 MPH OUT OF THE E AND
   NE. GIVEN STRONG HEATING...LOW RH AND LONG TERM DROUGHT
   CONDITIONS...THREAT FOR FIRES WILL BE ON THE INCREASE LOCALLY.

Day 2 Fire Weather Forecast graphic

   ZCZC SPCFWDDY2 ALL
   FNUS22 KWNS 031027
   
   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0527 AM CDT SAT SEP 03 2005
   
   VALID 041200Z - 051200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR SERN ID / SWRN MT / NWRN WY...
   
   ...SYNOPSIS...
   UPPER RIDGE AXIS WILL SHIFT EWD INTO THE UPPER MS VALLEY
   SUNDAY...ALLOWING BROAD AND WEAK UPPER TROUGH TO MOVE INTO THE GREAT
   BASIN AND PACIFIC NW WHERE IT WILL BE LOCALLY WINDY AND DRY. COOL
   AIR ALOFT WITH THIS TROUGH WILL ALLOW FOR SCATTERED THUNDERSTORMS
   OVER ERN ID AND WRN MT...AND SOME WILL BE DRY. ISOLATED DRY THUNDER
   WILL BE POSSIBLE SWD INTO THE WASATCH OF UT.
   
   FARTHER E...A LOW PRESSURE TROUGH WILL MOVE EWD ACROSS THE NRN
   PLAINS...WITH HIGH PRESSURE OVER THE ERN HALF OF THE NATION.
   PRESSURE GRADIENT BETWEEN THE TWO WILL CAUSE STRONG SLY WINDS TO
   DEVELOP THROUGH THE PLAINS STATES. DRY AIR ASSOCIATED WITH RH AND
   NELY WINDS MAY INCREASE FIRE THREAT ACROSS PORTIONS OF THE SRN
   PLAINS AND MS VALLEY...WEST OF WHERE HURRICANE KATRINA TRACKED.
   
   ...CRITICAL FIRE WEATHER AREA 1 - SERN ID / SWRN MT / NWRN WY...
   
   PRIMARY CONDITIONS: DRY LIGHTNING / LOW RH / MODERATE HAINES
   
   COOLING ALOFT WITH UPPER TROUGH WILL ALLOW FOR INCREASED INSTABILITY
   TO DEVELOP RESULTING IN AFTERNOON THUNDERSTORMS. GENERAL SSWLY FLOW
   WILL FAVOR SWRN SLOPES FOR DEVELOPMENT SUCH AS THE UPPER SNAKE RIVER
   PLAIN OF ID AND THE YELLOWSTONE AREA. GIVEN DRY AIR MASS IN
   PLACE...STORMS WILL CONTAIN LITTLE RAIN. IN ADDITION TO THE THREAT
   OF DRY THUNDER...SWLY WINDS WILL AVERAGE NEAR 15 MPH WITH HIGHER
   GUSTS AND MIN RH VALUES OF 15-20 PERCENT.
   
   ...NV / WRN UT...
   SLY SURFACE WINDS WILL AVERAGE NEAR 15 MPH WITH HIGHER GUSTS OVER 20
   MPH ESPECIALLY DURING THE AFTERNOON HOURS...WHILE MIN RH DROPS INTO
   THE 10-15 PERCENT RANGE.
   
   ...NERN TX / SERN OK / AR / NRN LA...
   HIGH PRESSURE WILL PERSIST AND KEEP CONDITIONS WARM AND DRY. MIN RH
   WILL DROP TO NEAR 30 PERCENT WITH TEMPERATURES IN THE 90S. ENELY
   WINDS AROUND 10 MPH ARE EXPECTED AND WITH DROUGHT CONDITIONS IN
   PLACE...THIS COULD CAUSE NEAR CRITICAL CONDITIONS TO DEVELOP LATE
   AFTERNOON IN AREAS THAT HAVE BEEN MISSED BY RECENT RAINS.
