VALID 221200Z - 231200Z
...EXTREMELY CRITICAL FIRE WEATHER AREA FOR THE MTNS/INTERIOR
VALLEYS OF SRN CA...
...CRITICAL FIRE WEATHER AREA FOR COASTAL VALLEYS OF SRN CA/CENTRAL
CA MTNS...
...CRITICAL FIRE WEATHER AREA FOR SRN AZ...
...SYNOPSIS...
AN UPPER TROUGH OVER THE PLAINS STATES WILL MOVE SLOWLY EWD AS IT
BECOMES REMOVED FROM THE NRN STREAM...AND SHOULD BECOME CLOSED OFF
BY THE END OF THE PERIOD. AHEAD OF THIS TROUGH...SCT PRECIPITATION
WILL DEVELOP OVER MUCH OF THE SRN PLAINS/SERN STATES. A STRONG UPPER
RIDGE WILL CONTINUE TO BUILD EWD INTO THE WRN STATES IN THE WAKE OF
THIS UPPER TROUGH. THIS UPPER RIDGE WILL PROVIDE FOR WARMING/DRY
CONDITIONS OVER CA AND MUCH OF THE GREAT BASIN. AT THE SFC...A COLD
FRONT WILL PUSH SEWD ACROSS THE SRN PLAINS/MS VALLEY. A BROAD AREA
OF SFC HIGH PRESSURE OVER THE GREAT BASIN/SRN ROCKIES WILL AID A
STRONG OFFSHORE WIND EVENT OF SRN CA AND MODERATE ELY WINDS OVER
PORTIONS OF AZ. COMBINED WITH LOW RH READINGS...CRITICAL FIRE
WEATHER CONDITIONS WILL EXIST IN THESE AREAS.
...EXTREMELY CRITICAL FIRE WEATHER AREA - THE MTNS/INTERIOR VALLEYS
OF SRN CA...
PRIMARY CONDITIONS: SUSTAINED NELY WINDS FROM 30-50 MPH WITH GUSTS
OVER 75 MPH...MIN RH READINGS FROM 4-8 PERCENT...LONG TERM DROUGHT
A VERY STRONG OFFSHORE WIND EVENT WILL CONTINUE EARLY IN THE PERIOD
/12-20Z/ ACROSS THE INTERIOR VALLEYS/MTNS OF SRN CA. THE STRONGEST
WINDS /SUSTAINED UP TO 50 MPH WITH GUSTS OVER 75 MPH/ WILL OCCUR
THROUGH AND BELOW PASSES AND CANYONS AND ALONG RIDGE TOPS WITH GUSTS
OVER 60 MPH IN INTERIOR VALLEYS. STRONG SUBSIDENCE AND PRESENCE OF
THE UPPER RIDGE CENTERED OVER NRN CA WILL PRODUCE NEAR RECORD HIGH
TEMPERATURES IN THE 90S IN LOWER ELEVATIONS AND 4-8 PERCENT RH
READINGS DURING THE DAY. WINDS WILL DIMINISH DURING THE AFTERNOON
HOURS...BEFORE RESTRENGTHENING OVERNIGHT.
...CRITICAL FIRE WEATHER AREA - SURROUNDING THE EXTREMELY CRITICAL
AREA - COASTAL VALLEYS OF SRN CA AND CENTRAL CA MTNS...
PRIMARY CONDITIONS: SUSTAINED NELY WINDS OF 20-30 MPH WITH GUSTS
OVER 50 MPH...MIN RH READINGS FROM 5-15 PERCENT
SURROUNDING THE EXTREMELY CRITICAL RISK AREA...WEAKER WINDS WILL
OCCUR IN THE IMMEDIATE COASTAL VALLEYS OF SRN CA AND CENTRAL CA
MTNS. HOWEVER...SUSTAINED NELY WINDS WILL STILL AVERAGE FROM 20-30
MPH WITH OCCASIONAL GUSTS OVER 50 MPH. MIN RH READINGS WILL BE
SLIGHTLY HIGHER IN THE COASTAL VALLEYS OF SRN CA THAN INTERIOR
VALLEYS/MTNS...BUT STILL WILL BE VERY LOW AS TEMPERATURES WARM INTO
THE UPPER 80S-MID 90S F. WINDS WILL STRENGTHEN THIS MORNING BEFORE
WEAKENING AGAIN LATE THIS AFTERNOON/EARLY EVENING.
...CRITICAL FIRE WEATHER AREA - SRN AZ...
PRIMARY CONDITIONS: SUSTAINED E-NE WINDS FROM 20-30 MPH WITH GUSTS
OVER 40 MPH...MIN RH READINGS FROM 5-10 PERCENT...LONG TERM DROUGHT
A STRONG PRESSURE/THERMAL GRADIENT WILL EXIST BETWEEN THE NRN
PLATEAU AND MOGOLLON RIM REGION/WRN NM AND THE LOWER DESERTS OF SRN
AZ THROUGH THE PERIOD. THE RESULT WILL BE MODERATE E-NELY WINDS FROM
20-30 MPH WITH HIGHER GUSTS. VERY DRY LOW LEVELS WITH MIN RH
READINGS FROM 4-10 PERCENT COMBINED WITH THESE WINDS WILL SUPPORT A
CRITICAL FIRE WEATHER THREAT TODAY.
...LOWER CO RIVER VALLEY...
MODEST NLY WINDS FROM 15-20 MPH WILL DEVELOP OVER PORTIONS OF THE
LOWER CO RIVER VALLEY GIVEN THE PRESENCE OF MODERATE N-S PRESSURE
GRADIENT. VERY DRY AIR WITH MIN RH READINGS FROM 5-10 PERCENT WILL
OCCUR AS TEMPERATURES WARM INTO THE LOWER 80S. GIVEN MARGINAL WIND
SPEEDS...A CRITICAL FIRE WEATHER AREA WILL NOT BE INCLUDED.
...SERN NM/SWRN TX...
IN THE WAKE OF A COLD FRONT/UPPER TROUGH PASSAGE...DEEP MIXING WILL
SUPPORT MODERATE NWLY WINDS FROM 15-25 MPH DURING THE AFTERNOON.
DESPITE MUCH COOLER TEMPERATURES THAN YESTERDAY....LITTLE CLOUD
COVER SHOULD STILL SUPPORT MILD TEMPERATURES IN THE 60S. MARGINAL RH
READINGS AROUND 20 PERCENT SHOULD PRECLUDE A CRITICAL FIRE WEATHER
THREAT.

DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0421 AM CDT MON OCT 22 2007
VALID 231200Z - 241200Z
...EXTREMELY CRITICAL FIRE WEATHER AREA FOR THE MTNS AND INTERIOR
VALLEYS OF SRN CA...
...CRITICAL FIRE WEATHER AREA FOR THE COASTAL VALLEYS OF SRN CA...
...CRITICAL FIRE WEATHER AREA FOR FAR SRN AZ...
...SYNOPSIS...
AN UPPER LOW WILL BECOME NEARLY STATIONARY OVER THE LOWER MS VALLEY
TOMORROW. SCT PRECIPITATION WILL OCCUR OVER MUCH OF THE SERN STATES
AHEAD OF THIS SYSTEM...AND AHEAD OF A NRN STREAM UPPER TROUGH OVER
MOVING THROUGH THE GREAT LAKES/NEW ENGLAND. IN THE WAKE OF THIS
SYSTEM...AN UPPER RIDGE WILL CONTINUE TO BUILD EWD INTO THE GREAT
BASIN. AT THE SURFACE...A BROAD AREA OF SFC HIGH PRESSURE WILL
REMAIN CENTERED OVER THE GREAT BASIN...WITH A SLOW WEAKENING IN
STRENGTH EXPECTED. THIS HIGH PRESSURE AREA WILL PROVIDE FOR A
CONTINUATION OF STRONG OFFSHORE PRESSURE/THERMAL GRADIENTS ACROSS
PORTIONS OF THE SOUTHWEST. THIS WILL RESULT IN ANOTHER DAY OF
CRITICAL/EXTREMELY CRITICAL FIRE WEATHER CONDITIONS OVER SRN CA AND
PORTIONS OF AZ. ELSEWHERE...GUSTY NWLY WINDS WILL DEVELOP OVER THE
SRN PLAINS TO THE WEST OF THE UPPER LOW. MILD TEMPERATURES AND LOW
RH READINGS WILL OCCUR OVER MUCH OF WRN/CENTRAL AND SRN TX ALONG
WITH THESE WINDS SUPPORTING NEAR CRITICAL CONDITIONS.
...EXTREMELY CRITICAL FIRE WEATHER AREA - THE MTNS/INTERIOR VALLEYS
OF SRN CA...
PRIMARY CONDITIONS: SUSTAINED NELY WINDS FROM 35-45 MPH WITH GUSTS
OVER 75 MPH...MIN RH READINGS FROM 4-8 PERCENT...LONG TERM DROUGHT
VERY STRONG OFFSHORE WIND EVENT WILL CONTINUE EARLY IN THE PERIOD
/12-20Z/ ACROSS THE INTERIOR VALLEYS/MTNS OF SRN CA. THE STRONGEST
WINDS /SUSTAINED UP TO 50 MPH WITH GUSTS OVER 75 MPH/ WILL OCCUR
THROUGH/BELOW PASSES AND CANYONS AND ALONG RIDGES. STRONG SUBSIDENCE
AND A STRONG UPPER RIDGE CENTERED OVER NRN CA WILL PRODUCE NEAR
RECORD HIGH TEMPERATURES IN THE 90S IN LOWER ELEVATIONS AND 4-8
PERCENT RH READINGS. WINDS WILL DIMINISH DURING THE AFTERNOON
HOURS...BEFORE RESTRENGTHENING OVERNIGHT. HOWEVER...A WEAKENING OF
OFFSHORE GRADIENTS TUE NIGHT SHOULD SUPPORT AT LEAST A 10-20 MPH
REDUCTION IN WIND GUSTS.
...CRITICAL FIRE WEATHER AREA - COASTAL VALLEYS OF SRN CA...
PRIMARY CONDITIONS: SUSTAINED NELY WINDS OF 20-30 MPH WITH GUSTS
OVER 40 MPH...MIN RH READINGS 4-10 PERCENT...LONG TERM DROUGHT
SURROUNDING THE EXTREMELY CRITICAL RISK AREA...WEAKER WINDS WILL
OCCUR IN THE COASTAL VALLEYS. HOWEVER...WINDS WILL STILL AVERAGE
FROM 20-30 MPH WITH GUSTS OVER 40 MPH EARLY IN THE PERIOD. WEAKENING
OFFSHORE GRADIENTS OVERNIGHT SHOULD LIMIT SUSTAINED WINDS TO LESS
THAN 20 MPH. LOW DEWPTS AND NEAR RECORD HIGH TEMPERATURES IN THE 90S
WILL PRODUCE VERY LOW RH READINGS FROM 4-10 PERCENT. SUSTAINED WINDS
WILL BE THE STRONGEST EARLY IN THE PERIOD....BEFORE WEAKENING TO
SUB-CRITICAL LEVELS DURING THE LATE AFTERNOON/EARLY EVENING.
...CRITICAL FIRE WEATHER AREA - FAR SRN AZ...
PRIMARY CONDITIONS: SUSTAINED E-NE WINDS FROM 15-25 MPH WITH GUSTS
OVER 30 MPH...MIN RH READINGS FROM 5-10 PERCENT...LONG TERM DROUGHT
A STRONG PRESSURE/THERMAL GRADIENT WILL EXIST BETWEEN SWRN NM AND
THE LOWER DESERTS OF SWRN AZ. THE RESULT WILL BE MODERATE E-NELY
WINDS FROM 20-30 MPH WITH HIGHER GUSTS ESPECIALLY DURING THE LATE
MORNING INTO THE MID-AFTERNOON HOURS. VERY DRY LOW LEVELS WITH MIN
RH READINGS FROM 5-10 PERCENT COMBINED WITH THESE WINDS WILL SUPPORT
A CRITICAL FIRE WEATHER THREAT.
...CENTRAL HIGH PLAINS SEWD INTO CENTRAL/SRN TX...
TO THE WEST OF THE UPPER LOW/TROUGH OVER THE LOWER MS
VALLEY...STRONG LOW-MID LEVEL WINDS WILL BE PRESENT. DEEP MIXING
DURING THE AFTERNOON WILL SUPPORT NWLY WINDS FROM 15-30 MPH. LOW
DEWPTS IN THE 20S/30S WILL COMBINE WITH TEMPS FROM 65-75 DEG F TO
PRODUCE MIN RH READINGS FROM 20-25 PERCENT. PRECIPITATION OVER
CENTRAL/SRN TX ALONG WITH MARGINAL RH READINGS OVER THE HIGH PLAINS
WILL PRECLUDE A CRITICAL FIRE WEATHER THREAT ISSUANCE AT THIS TIME.
