DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0419 AM CDT SAT AUG 11 2007
VALID 111200Z - 121200Z
...CRITICAL FIRE WEATHER AREA FOR A LARGE PORTION OF THE GREAT
BASIN...
...SYNOPSIS...
A BROAD UPPER RIDGE WILL REMAIN OVER THE CENTRAL CONUS THROUGH
TODAY. ON THE WRN PERIPHERY OF THIS RIDGE...A SHORTWAVE TROUGH OFF
THE CA COAST WILL MOVE NEWD ACROSS THE GREAT BASIN. IN ADDITION...A
STRONGER UPPER TROUGH OVER THE GULF OF ALASKA WILL MOVE SWD. THE
RESULT OF BOTH SYSTEMS WILL BE AN INCREASE IN SFC WINDS OVER A LARGE
PORTION OF THE GREAT BASIN. COMBINED WITH LOW RH READINGS...A
CRITICAL FIRE WEATHER THREAT WILL EXIST IN THIS REGION TODAY. A MIX
OF WET/DRY TSTMS ARE EXPECTED TO OCCUR ON THE LEADING EDGE OF MID
LEVEL MOISTURE THAT WILL ADVECT NWD THROUGH NRN AZ/SRN UT.
...CRITICAL FIRE WEATHER AREA - A LARGE PORTION OF THE GREAT
BASIN...
PRIMARY CONDITIONS: SUSTAINED SWLY WINDS FROM 15-25 MPH...MIN RH
READINGS AROUND 10 PERCENT...LONG TERM DROUGHT
A SHORTWAVE OFF THE CA COAST WILL MOVE INTO THE NRN ROCKIES THROUGH
TONIGHT. MEANWHILE...A STRONGER UPPER LOW OFF THE BRITISH COLUMBIA
COAST WILL MOVE SWD. AS A RESULT...THE MID LEVEL FLOW WILL INCREASE
OVER MUCH OF THE GREAT BASIN AND PAC NW. SUSTAINED SWLY WINDS FROM
15-25 MPH WILL DEVELOP AS A RESULT OF THE INCREASING MID LEVEL WINDS
AND DEEPENING AREA OF LOW PRESSURE OVER THE NRN ROCKIES.
...SRN UT...SRN NV AND NRN AZ...
AS A RESULT OF INCREASING SELY MID LEVEL WINDS...MOISTURE WILL MOVE
NWD INTO THE SRN GREAT BASIN/HIGH DESERT REGION OF SRN UT/NRN AZ...
SRN NV AND SERN CA. BASED ON FORECAST SOUNDINGS AND RECENT GOES
SOUNDER DATA...MOST OF THESE STORMS WILL BECOME WET WITH
TIME...MINIMIZING THE CRITICAL FIRE WEATHER THREAT.

DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0420 AM CDT SAT AUG 11 2007
VALID 121200Z - 131200Z
...CRITICAL FIRE WEATHER AREA FOR NRN GREAT BASIN/NRN ROCKIES...
...SYNOPSIS...
A BROAD UPPER RIDGE WILL REMAIN CENTERED OVER THE CENTRAL CONUS
THROUGH TOMORROW. MODERATE SWLY WINDS AT THE MID LEVELS ASSOCIATED
WITH AN UPPER TROUGH OVER THE PAC NW WILL SUPPORT MODERATE SFC WINDS
OVER THE NRN GREAT BASIN/NRN ROCKIES DURING THE PERIOD. COMBINED
WITH ABOVE NORMAL TEMPERATURES AND LOW RH READINGS...A CRITICAL FIRE
WEATHER THREAT WILL EXIST ACROSS THIS REGION. MID LEVEL MOISTURE
WILL CONTINUE TO ADVECT NWD THROUGH THE ERN GREAT BASIN. SCT TSTMS
ARE EXPECTED TO OCCUR IN THIS REGION...BUT AN EXPECTED MIX OF
WET/DRY TSTMS WILL PRECLUDE A CRITICAL FIRE WEATHER THREAT.
...CRITICAL FIRE WEATHER AREA - NRN GREAT BASIN/NRN ROCKIES...
PRIMARY CONDITIONS: SUSTAINED SWLY WINDS FROM 15-25 MPH...LOW RH
READINGS FROM 10-15 PERCENT...LONG TERM DROUGHT
IN BETWEEN AN UPPER TROUGH OFF THE PAC NW COAST AND AN UPPER RIDGE
OVER THE CENTRAL STATES...MODERATE MID LEVEL WINDS WILL EXIST OVER
THE NRN ROCKIES/NRN GREAT BASIN AND PAC NW. SOUTH AND EAST OF A
FRONTAL BOUNDARY THAT WILL BE LOCATED OVER INTERIOR WA/ORE...STEEP
LAPSE RATES WILL COMBINE WITH THESE WINDS TO SUPPORT MODERATE SWLY
SFC WINDS OVER THE NRN GREAT BASIN/NRN ROCKIES. WARM TEMPERATURES
AND LOW RH READINGS COMBINED WITH THESE WINDS WILL SUPPORT A
CRITICAL FIRE WEATHER THREAT OVER THE REGION.
...ERN GREAT BASIN...
MID LEVEL MOISTURE WILL LIFT NWD THROUGH THE ERN GREAT BASIN
TOMORROW ON THE WRN EDGE OF A STRONG RIDGE OVER THE CENTRAL STATES.
ALTHOUGH SFC RH READINGS WILL INITIALLY BE LOW OVER THE
REGION...SUFFICIENT DEPTH AND AMOUNT OF MID LEVEL MOISTURE SHOULD
SUPPORT A FAIRLY QUICK TRANSITION OF TSTMS FROM DRY TO WET...THUS
PRECLUDING ANY CRITICAL FIRE WEATHER OUTLOOK ATTM.
