DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0313 AM CDT WED AUG 30 2006
VALID 301200Z - 311200Z
...EXTREMELY CRITICAL FIRE WEATHER AREA FOR A PORTION OF CENTRAL/ERN
MT...ERN ID AND WRN/CENTRAL WY...
...CRITICAL FIRE WEATHER AREA FOR THE SRN GREAT BASIN NEWD INTO THE
NRN ROCKIES/NRN HIGH PLAINS...
...SYNOPSIS...
A STRONG UPPER TROUGH WILL SLOWLY MOVE EWD OVER THE NRN ROCKIES/NRN
GREAT BASIN THROUGH THE PERIOD. ASSOCIATED WITH THIS SYSTEM A COLD
FRONT WILL MOVE SEWD AND EXTEND FROM A SFC LOW PRESSURE CENTERED
OVER SERN MT SWWD INTO NRN NV BY EARLY EVENING. AHEAD OF THE
FRONT...AND WEST OF A LEE TROUGH...STRONG SWLY WINDS WILL DEVELOP
OVER THE SNAKE RIVER VALLEY AND MUCH OF WRN/CENTRAL WY INTO SCENTRAL
MT. BEHIND THE FRONT STRONG WNWLY WINDS WILL OCCUR OVER MUCH OF
WRN/CENTRAL MT AND PORTIONS OF SRN ID. LOW RH READINGS WILL COMBINE
WITH THESE WINDS TO PRODUCE EXTREMELY CRITICAL FIRE WEATHER
CONDITIONS MUCH OF THE NRN ROCKIES REGION. A CRITICAL FIRE WEATHER
THREAT WILL EXIST OVER MUCH OF THE REMAINDER OF THE GREAT BASIN NEWD
INTO THE NRN HIGH PLAINS WHERE SLIGHTLY WEAKER WIND SPEEDS WILL
EXIST. ELSEWHERE...A BROAD AREA OF SFC HIGH PRESSURE WILL DEVELOP
EWD ACROSS THE GREAT LAKES/MS VALLEY IN THE WAKE OF A WEAKENING
UPPER TROUGH. GENERALLY LIGHT WINDS AND NEAR/BELOW NORMAL
TEMPERATURES WILL BE A RESULT ACROSS MOST OF THIS REGION.
...EXTREMELY CRITICAL FIRE WEATHER AREA - MOST OF CENTRAL/ERN
MT...CENTRAL/WRN WY...PORTIONS OF SRN/ERN ID...
PRIMARY CONDITIONS: SUSTAINED SWLY-NWLY WINDS FROM 25-30 MPH WITH
GUSTS OVER 40 MPH...MIN RH READINGS FROM 10-15 PERCENT...WIND SHIFT
WITH A FRONTAL PASSAGE
A STRONG UPPER TROUGH WILL PROGRESS EWD ACROSS THE NRN ROCKIES
TODAY. AT THE SFC A COLD FRONT WILL EXTEND FROM A SFC LOW OVER SERN
MT SWWD INTO NWRN NV BY THE AFTERNOON HRS. WITH THE PASSAGE OF THE
FRONT...WINDS WILL SHIFT FROM SWLY TO NWLY DIRECTION AND INCREASE
SUPPORTED BY A STRONG PRESSURE GRADIENT AND STEEP LOW-MID LEVEL
LAPSE RATES. MINIMAL LOW LEVEL COOLING INITIALLY WITH THE FRONTAL
PASSAGE WILL SUPPORT CRITICAL FIRE WEATHER CONDITIONS FOR SEVERAL
HRS/50-100 MILES BEHIND THE COLD FRONT OVER CENTRAL/ERN MT AND
PORTIONS OF SRN/ERN ID DURING THE AFTERNOON. THE COMBINATION OF
SUSTAINED WIND SPEEDS FROM 20-30 MPH AND GUSTS UP TO 40 MPH
/STRONGEST OVER THE SNAKE RIVER VALLEY AND BEHIND THE FRONT OVER
CENTRAL MT/ ALONG WITH MIN RH READINGS FROM 10-15 PERCENT SUPPORTS A
EXTREMELY CRITICAL FIRE WEATHER THREAT. IN ADDITION TO THE WIND/RH
RELATED THREAT...ISOLATED DRY TSTMS WILL ALSO BE POSSIBLE OVER MUCH
OF WY AND SRN MT JUST AHEAD OF THE COLD FRONT/LEE TROUGH.
...CRITICAL FIRE WEATHER AREA - SURROUNDING THE EXTREMELY CRITICAL
FIRE WEATHER AREA...FROM THE GREAT BASIN NEWD INTO CENTRAL
ROCKIES/NRN HIGH PLAINS...
PRIMARY CONDITIONS: SUSTAINED SWLY WINDS FROM 20-30 MPH WITH GUSTS
OVER 35 MPH...MIN RH READINGS FROM 5-15 PERCENT
SOUTH OF THE STRONGEST MID LEVEL WIND FIELDS...LOW RH READINGS WILL
AGAIN BE COMMON ALONG WITH MODERATE SWLY WINDS FROM 20-30 MPH. THE
ERN EDGE OF THE CRITICAL AREA WILL EXTEND ALONG AND JUST EAST OF THE
LEE TROUGH WHERE A MODERATE PRESSURE GRADIENT WILL EXIST ALONG WITH
SLOWLY INCREASING MID LEVEL WIND FIELDS/STEEP LAPSE RATES. ISOLATED
MAINLY DRY TSTMS WILL ALSO BE POSSIBLE OVER FAR ERN WY/MT AND FAR
WRN SD/ND DURING THE LATE AFTERNOON/EVENING HRS.
...PORTIONS OF CENTRAL/SCENTRAL TX...
IN THE WAKE OF A COLD FRONT...MUCH LOWER DEWPTS /50S/ WILL FILTER
SWD INTO THE REGION TODAY. HOWEVER TEMPERATURES WILL REMAIN NEAR
SEASONAL NORMS /LOWER-MID 90S/ PRODUCING MIN RH READINGS FROM 20-30
PERCENT. EARLY MORNING PROFILER DATA INDICATED A NLY LOW LEVEL JET
OF 20-30 KTS IN THE LOWER FEW THOUSAND FEET OVER CENTRAL/ERN TX.
SIMILAR CONDITIONS WERE OBSERVED OVER OK YESTERDAY MORNING...AND
DESPITE GRADUAL WEAKENING OF THIS WIND MAX THE REMAINDER OF THE
MORNING SUSTAINED WINDS AROUND 15 MPH WITH OCCASIONAL WIND GUSTS UP
TO 25 MPH CAN BE EXPECTED TODAY OVER PORTIONS OF CENTRAL/SRN TX.
COMBINED WITH THE LOW RH READINGS AND LONG TERM SIGNIFICANT
DROUGHT...VERY HIGH FIRE DANGER IS EXPECTED. LACK OF STRONGER
SUSTAINED WINDS WILL PRECLUDE A CRITICAL FIRE WEATHER THREAT.

DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0317 AM CDT WED AUG 30 2006
VALID 311200Z - 011200Z
...NO CRITICAL AREAS...
...SYNOPSIS...
A STRONG UPPER TROUGH OVER THE NRN ROCKIES WILL SLOWLY MOVE EWD
THROUGH THE PERIOD. SOUTH OF A COLD FRONT...MODERATE SWLY WINDS/LOW
RH READING WILL DEVELOP OVER PORTIONS OF WY AND COLORADO. WINDS ARE
NOT ANTICIPATED TO BE AS STRONG AS TODAY...SO CRITICAL FIRE WEATHER
CONDITIONS ARE NOT EXPECTED. BEHIND THE FRONT...NWLY WINDS WILL
AVERAGE FROM 20-25 MPH OVER ND/MT AND NRN WY...BUT COOLER
TEMPERATURES WILL KEEP MIN RH READINGS ABOVE 25 PERCENT. UPPER
RIDGING WILL BEGIN TO REASSERT ITSELF OVER THE WEST COAST LEADING TO
INCREASING TEMPERATURES/ LOWERING RH READINGS IN THIS REGION.
ELSEWHERE ACROSS THE NATION SFC HIGH PRESSURE AND THE EFFECTS FROM A
WEAK UPPER TROUGH WILL PRECLUDE ANY CRITICAL FIRE WEATHER THREATS
...SRN WY/NWRN CO...
SOUTH OF A COLD FRONT SWLY WINDS WILL INCREASE TO AROUND 20 MPH
DURING THE AFTERNOON. VERY DRY AIR WILL SUPPORT MIN RH READINGS
AROUND 15 PERCENT. LACK OF STRONGER SUSTAINED WINDS WILL PRECLUDE A
CRITICAL FIRE WEATHER THREAT.
