VALID 221200Z - 231200Z
...NO CRITICAL AREAS...
...SYNOPSIS...
AN UPPER TROUGH WILL SAG SWD ACROSS THE WRN STATES INTO THE GREAT
BASIN WITH A WEAK FRONT MOVING INTO THE NRN GREAT BASIN THIS
AFTERNOON. THIS FRONT WILL SERVE AS A FOCUS FOR ISOLATED
THUNDERSTORMS...SOME DRY. SOUTH OF THIS FRONT...VERY WARM AND DRY
CONDITIONS WILL PERSIST...WITH LOCALLY GUSTY WINDS.
FARTHER E...LOW PRESSURE WILL DEEPEN OVER ERN CO/WRN KS AND WILL
INDUCE VERY STRONG SLY WINDS ACROSS THE CNTRL AND SRN HIGH
PLAINS...WHILE UPPER RIDGE REMAINS CENTERED OVER THE LOWER MS
VALLEY/GULF COAST WITH VERY HOT AND DRY WEATHER AND PERSISTENT
DROUGHT.
...NERN NV...NRN UT...SERN ID...WRN WY...
AN APPROACHING TROUGH ALOFT AND WEAK SURFACE FRONT WILL RESULT IN
ISOLATED THUNDERSTORMS THIS AFTERNOON FROM NERN NV INTO NRN UT/SERN
ID/WRN WY. THE GREATEST THREAT OF DRY LIGHTNING WILL BE FROM ERN NV
INTO PORTIONS OF UT...WHERE SUB-CLOUD RH LEVELS WILL BE LOWEST. IN
GENERAL...A MIXTURE OF DRY AND WET STORMS ARE EXPECTED. CRITICAL
COVERAGE OF DRY LIGHTNING IS NOT ANTICIPATED THOUGH...GIVEN ONLY
ISOLATED COVERAGE. ANY STRIKES WILL HAVE A HIGH IGNITION EFFICIENCY.
...SRN GREAT BASIN INTO NRN AZ/SRN CA...
A VERY HOT...DRY AND UNSTABLE ATMOSPHERE WILL EXIST THIS AFTERNOON
WITH A HIGH HAINES INDEX EXPECTED. SUSTAINED WINDS ON THE LARGE
SCALE ARE EXPECTED TO REMAIN AT OR BELOW 15 MPH...BUT HIGHER GUSTS
WILL BE COMMON. THE GREATEST THREAT WILL BE FOR AFTERNOON PLUME
DOMINATION WITH ONGOING FIRES.
..,.AL/GA/SC...
VERY HOT AND DRY CONDITIONS WILL CONTINUE UNDER UPPER RIDGE.
TEMPERATURES OVER 100 F WILL RESULT IN MIN RH VALUES FROM 20-30
PERCENT BY AFTERNOON. WINDS WILL BE LIGHT BUT LOW LEVELS WILL BE
VERY UNSTABLE AND WILL FAVOR FIRE GROWTH.
...ERN MT...MD...NWRN MN...
IT WILL BE COOL BUT WINDY AND DRY IN A POST FRONTAL REGIME.
SUSTAINED WLY WINDS AROUND 20 MPH ARE EXPECTED WITH HIGHER GUSTS
WHILE TEMPERATURES APPROACH 80 F AND RH DROPS INTO THE 20 PERCENT
RANGE MT/WRN ND AND NEAR 30 PERCENT NW MN...RESULTING IN A MARGINAL
FIRE THREAT THIS AFTERNOON.

DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0453 AM CDT WED AUG 22 2007
VALID 231200Z - 241200Z
...CRITICAL FIRE WEATHER AREA FOR ERN NV...CNTRL UT...WRN CO...
...SYNOPSIS...
AN UPPER TROUGH WILL AMPLIFY AND DIG SEWD ACROSS THE GREAT BASIN
RESULTING IN SCATTERED DRY THUNDERSTORMS FROM ERN NV ACROSS UT INTO
WRN CO. WINDS WILL ALSO INCREASE ALONG AND SOUTH OF THE COLD
FRONT...FROM THE SRN GREAT BASIN INTO NRN AZ AND SRN CA. FARTHER
E...A VERY WARM AIR MASS WILL REMAIN FROM THE SRN PLAINS INTO THE
LOWER MS VALLEY/GULF COAST AREA. VERY LOW RH WILL EXIST OVER
PORTIONS OF TN/MS/AL/GA.
...CRITICAL FIRE WEATHER AREA - ERN NV...CNTRL UT...WRN CO...
PRIMARY CONDITIONS: DRY THUNDERSTORMS AND GUSTY WINDS
LARGE SCALE LIFT WITH APPROACHING UPPER TROUGH ALONG WITH A SURFACE
FRONT WILL HELP TO FOCUS AN AREA OF THUNDERSTORMS THURSDAY AFTERNOON
FROM ERN NV ACROSS UT INTO WRN CO. SOME STORMS ALONG AND NORTH OF
THE COLD FRONT WILL HAVE RAIN...BUT THE SRN HALF OF THE AREA OF
STORMS SHOULD BE DRY WITH LOW RH BELOW CLOUD BASE. IN
ADDITION...SWLY WINDS OF 15-20 MPH ARE EXPECTED WHICH WILL FURTHER
INCREASE FIRE DANGER.
...TN/MS/AL...
UPPER RIDGE CENTER WILL REMAIN OVERHEAD AND WILL RESULT IN HOT AND
DRY CONDITIONS. RH LEVELS WILL DROP TO CRITICALLY LOW LEVELS OF
20-30 PERCENT BUT WINDS WILL BE LIGHT. THE MAIN THREAT WILL BE FOR
AFTERNOON FIRE GROWTH GIVEN A DEEPLY MIXED AND UNSTABLE BOUNDARY
LAYER AND HIGH HAINES INDEX.
...SRN NV/UT...NWRN AZ...SRN CA...
BORDERLINE CRITICAL FIRE WEATHER CONDITIONS ARE ANTICIPATED ON
THURSDAY AS UPPER TROUGH APPROACHES. WINDS WILL INCREASE WITH
SUSTAINED SPEEDS OF 15-25 MPH AND HIGHER GUSTS. HUMIDITY LEVELS ARE
FORECAST TO ONLY BE MARGINALLY LOW OVER MUCH OF AZ WITH AMPLE LOW
LEVEL MOISTURE...BUT RH WILL DRY QUICKLY WITH WWD EXTEND TO NEAR 15
PERCENT ACROSS THE LOWER CO RIVER VALLEY...SRN NV...SWRN UT AND SERN
CA WHERE HOT TEMPERATURES WILL EXIST.
