...EXTREMELY CRITICAL FIRE WEATHER AREA FOR A PORTION OF THE SRN
GREAT BASIN...
...CRITICAL FIRE WEATHER AREA FOR SURROUNDING THE EXTREMELY CRITICAL
AREA OVER A LARGE PORTION OF THE SOUTHWEST/SRN ROCKIES REGION...
...SYNOPSIS...
A STRONG UPPER SYSTEM WILL DIG INTO THE WEST COAST THROUGH TODAY.
AHEAD OF THIS SYSTEM...A LARGE AREA OF MODERATE TO STRONG SFC WINDS
AND WARM TEMPERATURES/LOW RH READINGS WILL COMBINE TO PRODUCE A
CRITICAL FIRE WEATHER THREAT OVER A LARGE PORTION OF THE
SOUTHWEST/SRN ROCKIES AND SRN GREAT BASIN. WHERE THE STRONGEST SFC
WINDS WILL EXIST...EXTREMELY CRITICAL FIRE WEATHER CONDITIONS ARE
EXPECTED. ELSEWHERE A BROAD UPPER TROUGH OVER THE ERN CONUS WILL
GRADUALLY SHIFT EWD. IN IT'S WAKE...SFC HIGH PRESSURE WILL BUILD
EWD...PROVIDING FOR A DRYING TREND TO MUCH OF THIS REGION. ALTHOUGH
PORTIONS OF THE SERN STATES WILL SEE RH READINGS APPROACHING
CRITICAL LEVELS...RECENT PRECIPITATION AND SUSTAINED WINDS LESS THAN
15 MPH WILL PRECLUDE A CRITICAL FIRE WEATHER THREAT.
...EXTREMELY CRITICAL FIRE WEATHER AREA - PORTIONS OF SRN NV...SWRN
UT AND NWRN AZ...
PRIMARY CONDITIONS: SUSTAINED SWLY WINDS FROM 30-35 MPH WITH GUSTS
UP TO 50 MPH...MIN RH READINGS FROM 5-10 PERCENT...LONG TERM DROUGHT
AN UNSEASONABLY STRONG UPPER TROUGH WILL DIG SEWD INTO THE WEST
COAST AND GREAT BASIN THROUGH TONIGHT. AHEAD OF THE TROUGH...STRONG
MID LEVEL WINDS WILL MOVE INTO THE SRN GREAT BASIN AND THE
SOUTHWESTERN STATES. THE STRONGEST MID LEVEL WINDS ARE EXPECTED TO
EXTEND SW-NE FROM ERN CA INTO SRN NV/NWRN AZ AND SWRN UT DURING PEAK
HEATING. STEEP LOW-MID LEVEL LAPSE RATES WILL SUPPORT MOMENTUM
TRANSFER OF THESE STRONG WINDS TO THE SFC. AS A RESULT SUSTAINED
SWLY WINDS FROM 30-35 MPH WITH GUSTS UP TO 50 MPH ARE EXPECTED THIS
AFTERNOON...WITH ABOVE CRITICAL WIND SPEEDS LASTING MOST OF THE
NIGHT. ABOVE NORMAL TEMPERATURES/LONG TERM DROUGHT AND LOW RH
READINGS FROM 5-10 PERCENT WILL COMBINE WITH THESE WINDS TO SUPPORT
AN EXTREMELY CRITICAL FIRE WEATHER THREAT. STRONG WINDS OVERNIGHT
SHOULD PROVIDE FOR POOR RH RECOVERY.
...CRITICAL FIRE WEATHER AREA - THE REMAINDER OF SRN NV...MOST OF
UT/AZ..SERN CA...WRN CO AND WRN NM...
PRIMARY CONDITIONS: SUSTAINED SWLY WINDS FROM 20-30 MPH WITH GUSTS
UP TO 40 MPH...MIN RH READINGS FROM 5-15 PERCENT...LONG TERM DROUGHT
CONDITIONS
SURROUNDING THE EXTREMELY CRITICAL FIRE WEATHER AREA...A LARGE AREA
OF CRITICAL FIRE WEATHER CONDITIONS WILL OCCUR AS THE STRONG UPPER
TROUGH MOVES TOWARDS THE REGION. A VERY DRY AIRMASS WITH MIN RH
READINGS FROM 5-15 PERCENT /LOWEST OVER AZ/SERN CA AND SRN/WRN UT/
WILL COMBINE WITH THE STRONG WINDS TO SUPPORT CRITICAL FIRE WEATHER
CONDITIONS. SUSTAINED WINDS SHOULD REMAIN ABOVE CRITICAL LEVELS OVER
WRN PORTIONS OF THE CRITICAL FIRE WEATHER OUTLOOK AREA OVERNIGHT
WHERE THE STRONGEST MID LEVEL WINDS WILL EXIST. THE ONE EXCEPTION TO
THIS WILL BE WHERE A COLD FRONT WILL PUSH SEWD THROUGH CENTRAL
NV/NWRN UT AIDING IN THE END OF CRITICAL CONDITIONS OVERNIGHT.
...ERN/CENTRAL NM...SERN CO AND FAR WRN TX...
VERY LOW RH READINGS AND GUSTY SWLY WINDS /20-25 MPH/ WILL DEVELOP
OVER THE SRN HIGH PLAINS AND CENTRAL NM TODAY. RECENT MOIST SPELL IN
THESE AREAS WILL PRECLUDE CRITICAL FIRE WEATHER THREAT DESPITE THESE
SENSIBLE WEATHER CONDITIONS.

DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0424 AM CDT TUE JUN 05 2007
VALID 061200Z - 071200Z
...EXTREMELY CRITICAL FIRE WEATHER AREA FOR ECENTRAL AZ...WCENTRAL
NM...
...CRITICAL FIRE WEATHER AREA FOR SURROUNDING THE EXTREMELY CRITICAL
RISK AREA INCLUDING MUCH OF AZ...WRN NM AND THE FOUR CORNERS AREA...
...SYNOPSIS...
A STRONG UPPER SYSTEM WILL MOVE INTO THE ROCKIES THROUGH TOMORROW.
ASSOCIATED WITH THIS SYSTEM...STRONG SFC WINDS WILL COMBINE WITH LOW
RH READINGS TO PRODUCE CRITICAL FIRE WEATHER CONDITIONS OVER A LARGE
PORTION OF THE SOUTHWEST. AS A RESULT OF THE APPROACHING UPPER
SYSTEM...SLY WINDS WILL INCREASE OVER THE PLAINS...WITH LOW RH
READINGS OVER THE SRN/CENTRAL HIGH PLAINS. MEANWHILE...A LARGE AREA
OF SFC HIGH PRESSURE WILL RESIDE OVER THE ERN STATES. UNDER THE
PRESENCE OF RIDGING ALOFT...WARM TEMPERATURES WILL LEAD TO LOW RH
READINGS OVER MUCH OF THE SOUTHEAST/CAROLINAS...BUT LIGHT WINDS WILL
PRECLUDE ANY CRITICAL FIRE WEATHER CONCERNS.
...EXTREMELY CRITICAL FIRE WEATHER AREA - ECENTRAL AZ/WCENTRAL NM...
PRIMARY CONDITIONS: SUSTAINED SWLY WINDS FROM 30-35 MPH WITH GUSTS
UP TO 50 MPH...MIN RH READINGS FROM 5-10 PERCENT
THE STRONGEST SFC WINDS ARE EXPECTED TO DEVELOP OVER THIS AREA WHERE
MODERATE MID LEVEL COLD ADVECTION IN THE WAKE OF AN INITIAL
SHORTWAVE TROUGH WILL COMBINE WITH WARM SFC TEMPERATURES TO SUPPORT
NEARLY DRY ADIABATIC LAPSE RATES FROM THE SFC TO MID LEVELS. THIS
WILL AID IN MOMENTUM TRANSFER OF THE STRONG MID LEVEL WINDS THAT
MOVES ACROSS THIS AREA DURING THE AFTERNOON. ALTHOUGH TEMPERATURES
WILL BE COOLER THAN DAY 1...THE STRENGTH OF THE SFC WINDS AND VERY
LOW RH READINGS FROM 5-10 PERCENT /AIDED BY DEWPTS FROM 10-20 DEG F/
WILL SUPPORT AN EXTREMELY CRITICAL FIRE WEATHER THREAT. WITH THE
DEPARTURE OF THE MID LEVEL SPEED MAX DURING THE EVENING
HOURS...SUSTAINED WINDS SHOULD DIMINISH BELOW CRITICAL LEVELS BY
MIDNIGHT IN MOST LOCATIONS.
...CRITICAL FIRE WEATHER AREA - MUCH OF AZ...WRN NM...FAR SERN
UT/SWRN CO...
PRIMARY CONDITIONS: SUSTAINED SWLY WINDS FROM 20-30 MPH WITH GUSTS
TO 45 MPH....MIN RH READINGS FROM 5-15 PERCENT...LONG TERM DROUGHT
SURROUNDING THE EXTREMELY CRITICAL FIRE WEATHER AREA...SUSTAINED
WINDS WILL BE A LITTLE WEAKER /WRN...NRN AND SERN AZ...SWRN AND NWRN
NM/. HOWEVER...SUSTAINED WINDS WILL STILL AVERAGE FROM 20-30 MPH
WITH HIGHER GUSTS IN THESE AREAS. OVER NRN AZ/NWRN NM AND FAR SERN
UT/SWRN CO...SUSTAINED WINDS WILL AVERAGE 25-30 MPH WITH GUSTS TO 45
MPH IN CLOSER PROXIMITY TO THE MID LEVEL JET. MIN RH READINGS IN
THIS AREA ARE EXPECTED TO BE JUST BELOW 15 PERCENT FOR MOST OF THE
AFTERNOON AS MORE CLOUD COVER SHOULD EXIST.
...SRN/CENTRAL HIGH PLAINS...
THE STRONGEST SFC WINDS /SUSTAINED 35-45 MPH WITH GUSTS OVER 60 MPH/
ARE EXPECTED TO OCCUR OUTSIDE OF THE CRITICAL AREAS FROM ERN NM/WRN
TX INTO ERN CO/WRN KS...WHERE VERY STEEP LAPSE RATES EXIST FROM THE
SFC TO MID LEVELS AND A STRONG MID LEVEL SPEED MAX MOVES OUT INTO
THE AREA DURING THE AFTERNOON. ABOVE NORMAL TEMPERATURES FROM 85-105
DEG F ARE EXPECTED TO DEVELOP ALONG THE SFC THERMAL RIDGE AHEAD OF
THE UPPER TROUGH. COMBINED WITH LOW DEWPTS...MIN RH READINGS FROM
5-15 PERCENT WILL BE PRESENT OVER THE AREA. RECENT/LONG TERM MOIST
CONDITIONS OVER THIS AREA ARE EXPECTED TO PRECLUDE A CRITICAL FIRE
WEATHER THREAT...DESPITE THESE EXTREME SENSIBLE FIRE WEATHER
CONDITIONS.
