VALID 041200Z - 051200Z
...CRITICAL FIRE WEATHER AREA FOR NWRN MT...
...CRITICAL FIRE WEATHER AREA FOR NERN CA...NWRN NV...FAR SERN
OREGON...
...SYNOPSIS...
AN UPPER TROUGH WILL REMAIN OVER THE PACIFIC NW...AND WILL GRADUALLY
SINK SWD INTO THE WRN GREAT BASIN LATE IN THE PERIOD. A LEAD
SHORTWAVE TROUGH WILL CONTINUE EWD INTO MANITOBA...LEAVING A COLD
FRONT IN ITS WAKE OVER MT...WHERE DRY WLY WINDS WILL CREATE LOCALLY
CRITICAL CONDITIONS. FLOW ALOFT WILL ALSO INCREASE INTO THE WRN
GREAT BASIN AND WILL CREATE CRITICAL CONDITIONS FROM NERN CA INTO
THE FAR WRN GREAT BASIN WITH GUSTY WINDS AND LOW RH.
ELSEWHERE...HIGH PRESSURE WILL SETTLE ACROSS THE GREAT LAKES REGION
WITH DRY AND MILD CONDITIONS. WARM AND BREEZY CONDITIONS WILL
PREVAIL ACROSS THE CNTRL PLAINS SOUTH OF A COLD FRONT WHICH WILL
EXTEND FROM MN INTO NEBRASKA WITH NUMEROUS THUNDERSTORMS.
...CRITICAL FIRE WEATHER AREA - NWRN MT...
PRIMARY CONDITIONS: STRONG WIND GUSTS...LOW RH...SHIFTING WINDS
WLY WINDS WILL INCREASE THROUGH THE DAY BEHIND A COLD FRONT.
SUSTAINED SPEEDS OF 15-20 MPH WILL BE WIDESPREAD...WITH HIGHER GUSTS
TO AROUND 30 MPH MAINLY NEAR RIDGE TOPS. RH WILL DECREASE TO AROUND
15 PERCENT BY LATE AFTERNOON. THE DOWNSLOPE WINDS AND STRONG HEATING
WILL RESULT IN DEEP MIXING LAYERS WHICH WILL BE FAVORABLE FOR FIRE
GROWTH. WINDS WILL WEAKEN LATE IN THE DAY BUT WILL SHIFT TO MORE OF
A NLY DIRECTION WHICH MAY RESULT IN CHANGING FIRE DIRECTION.
...CRITICAL FIRE WEATHER AREA - NERN CA...NWRN NV...FAR SERN
OREGON...
PRIMARY CONDITIONS: STRONG WINDS...VERY LOW RH...MDT HAINES
MID TO UPPER LEVEL WINDS WILL INCREASE ACROSS THE REGION AS UPPER
TROUGH SINKS SWD OUT OF THE PACIFIC NW. STRONG HEATING AND WLY
DOWNSLOPE FLOW WILL RESULT IN SUSTAINED WINDS NEAR 20 MPH WITH
HIGHER GUSTS OVER 30 MPH. MIN RH WILL LIKELY AVERAGE NEAR 10 PERCENT
BY AFTERNOON. THE DEEPLY MIXED AND DRY AIR MASS WILL RESULT IN A MDT
HAINES INDEX.
...SWRN MT...ERN ID...NWRN WY...
PRESENCE OF COOL AIR ALOFT WITH UPPER TROUGH...HEATING AND SWLY FLOW
WILL RESULT IN ISOLATED TO SCATTERED THUNDERSTORMS THIS AFTERNOON. A
MIXTURE OF WET AND DRY STORMS IS LIKELY. SUB-CLOUD LAYER RH WILL
AVERAGE 25-35 PERCENT WHICH WILL FAVOR EVAPORATION OF RAIN AND GUSTY
WINDS. DEEP LAYER WIND SHEAR WILL BE FAVORABLE FOR A FEW STRONG
STORMS...WHICH WOULD CONTAIN RAIN AND GUSTY WINDS.

DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0405 AM CDT SAT AUG 04 2007
VALID 051200Z - 061200Z
...CRITICAL FIRE WEATHER AREA FOR NERN CA...NWRN NV...SERN OR...
...SYNOPSIS...
UPPER RIDGE WILL WEAKEN A BIT ACROSS THE WRN STATES AS SHORTWAVE
TROUGH MOVES ACROSS CA INTO THE WRN GREAT BASIN. WINDS WILL LIKELY
BE A BIT STRONGER THAN PREVIOUS DAY WITH CONTINUED LOW RH. THIS
APPROACHING UPPER TROUGH WILL ALSO RESULT IN STRONGER WINDS OVER THE
SRN GREAT BASIN INTO SRN CA. A FEW DRY THUNDERSTORMS ARE LIKELY AS
WELL...MAINLY OVER NV LATE. MEANWHILE...SURFACE FRONT WILL SETTLE
OVER SRN MT WITH MAINLY LIGHT NLY WINDS PREVAILING N OF THE FRONT.
...CRITICAL FIRE WEATHER AREA - NERN CA...NWRN NV...SERN OR...
PRIMARY CONDITIONS: STRONG WIND GUSTS...LOW RH
SUSTAINED SWLY WINDS NEAR 20 MPH WILL OCCUR WITH HIGHER GUSTS TO 30
MPH. THIS WILL COMBINE WITH RH NEAR 15 PERCENT AND VERY DRY FUELS TO
PRODUCE CRITICAL CONDITIONS DURING THE AFTERNOON/PEAK HEATING HOURS.
WINDS MAY REMAIN GUSTY NEAR RIDGE TOPS WITH UPPER JET OVERHEAD. IN
ADDITION...THE APPROACHING SHORTWAVE ALOFT AND ASSOCIATED MOISTURE
AND LIFT COULD RESULT IN A FEW DRY THUNDERSTORMS. AT THIS TIME IT
APPEARS ANY STORMS WOULD BE ISOLATED DUE TO LITTLE IF ANY
INSTABILITY...BUT WILL CONTINUE TO MONITOR.
...SRN CA DESERTS...
PRESSURE GRADIENT WILL INCREASE BETWEEN MARINE LAYER AND HEAT LOW
ACROSS THE MOJAVE DESERT...RESULTING IN GUSTY WINDS FROM THE
ANTELOPE VALLEY INTO OWENS AND DEATH VALLEYS. SUSTAINED SWLY WINDS
OF 20 MPH APPEAR LIKELY WITH HIGHER GUSTS WITH MODERATELY LOW RH OF
10-15 PERCENT.
