DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0453 AM CDT FRI AUG 31 2007
VALID 311200Z - 011200Z
...CRITICAL FIRE WEATHER AREA FOR THE NRN ROCKIES...
...SYNOPSIS...
AN UPPER TROUGH WILL MOVE INTO THE PAC NW THROUGH THE PERIOD. AHEAD
OF THIS TROUGH...MID LEVEL MOISTURE WILL SPREAD ACROSS THE NRN
ROCKIES. THE INTERACTION OF THIS MOISTURE WITH THE FORCING AHEAD OF
THE TROUGH WILL PRODUCE SCT TO NMRS TSTMS OVER THE NRN ROCKIES. A
DEEPLY MIXED/DRY BOUNDARY LAYER ACROSS THIS AREA WILL SUPPORT MAINLY
DRY TSTMS...PRESENTING A CRITICAL FIRE WEATHER THREAT. ELSEWHERE
ACROSS THE NATION...SCT TSTMS ARE EXPECTED FROM THE DESERT SW INTO
THE SERN STATES.
...CRITICAL FIRE WEATHER AREA - NRN ID...WRN/CENTRAL MT...
PRIMARY CONDITIONS: SCT DRY TSTMS
AN UPPER SYSTEM WILL MOVE FROM NRN CA/SRN ORE INTO THE NRN ROCKIES.
SCT TSTMS WILL DEVELOP AHEAD OF THIS SYSTEM THROUGH THE AFTERNOON.
ADDITIONAL AND A GREATER CONCENTRATION OF TSTMS ARE EXPECTED TO
DEVELOP AHEAD OF A STRONGER UPPER TROUGH MOVING INTO THE PAC NW.
WHERE THE BOUNDARY LAYER WILL BE THE DRIEST /WRN AND CENTRAL
MT/...MOST OF THE CONVECTION IS EXPECTED TO BE DRY. FURTHER
WEST...OVER NRN ID...GREATER MOISTURE WILL LIKELY LEAD TO A MIX OF
WET/DRY TSTMS. STRENGTHENING MID LEVEL FLOW IN THIS AREA WILL
SUPPORT FASTER STORM MOTIONS LEADING TO NMRS LIGHTNING STRIKES WITH
LITTLE ASSOCIATED PRECIPITATION.

DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0455 AM CDT FRI AUG 31 2007
VALID 011200Z - 021200Z
...NO CRITICAL AREAS...
...SYNOPSIS...
IN THE WAKE OF A LEAD SHORTWAVE TROUGH...A SFC LEE TROUGH AND COLD
FRONT WILL MOVE THROUGH THE NRN PLAINS. DRY AIR AND MODERATE WINDS
WILL LEAD TO NEAR CRITICAL FIRE WEATHER CONDITIONS. FURTHER WEST...A
SECONDARY UPPER TROUGH WILL MOVE INTO THE PAC NW. AHEAD OF AN
ASSOCIATED COLD FRONT...ISOLATED DRY TSTMS ARE POSSIBLE OVER THE NRN
GREAT BASIN/INTERIOR PAC NW. ADDITIONAL ISOLATED DRY TSTMS WILL BE
POSSIBLE OVER SRN CA AS MONSOONAL MOISTURE ROTATES AROUND THE BROAD
UPPER RIDGE CENTERED OVER THE SRN GREAT BASIN. ELSEWHERE ACROSS THE
NATION...SCT TSTMS WILL AGAIN BE PRESENT OVER THE SERN STATES.
...NRN PLAINS...
TO THE WEST OF A LEE TROUGH AND ALONG AND JUST BEHIND A COLD
FRONT...WNWLY WINDS WILL GUST OVER 25 MPH DURING THE AFTERNOON. WARM
TEMPERATURES IN THE UPPER 80S-MID 90S WILL SUPPORT MIN RH READINGS
AROUND 20 PERCENT.
...INTERIOR WA/ORE AND WRN ID...
AHEAD OF A SECOND UPPER TROUGH...MID LEVEL MOISTURE WILL MOVE NWD
INTO THE REGION. SCT TSTMS ARE EXPECTED TO DEVELOP OVER THE AREA
DURING THE LATE AFTERNOON INTO THE OVERNIGHT. FORECAST SOUNDINGS
INDICATE THAT SOME OF THESE TSTMS WILL BE DRY GIVEN THE RELATIVELY
DEEPLY MIXED DRY BOUNDARY LAYER BENEATH THE TSTMS BASES. AREA WILL
BE MONITORED FOR A GREATER COVERAGE OF TSTMS AND POSSIBLE CRITICAL
THREAT IN A LATER OUTLOOK.
...SRN CA...
AS THE UPPER RIDGE CENTER MOVES NWD INTO THE SRN GREAT BASIN...ELY
MID LEVEL WINDS WILL DEVELOP OVER SRN CA SUPPORTING MID LEVEL
MOISTURE INCREASE TOMORROW. ALTHOUGH RELATIVELY HIGH PWAT VALUES
WILL SUPPORT A TRANSITION TO WET TSTMS...TSTMS ARE EXPECTED TO BE
INITIALLY DRY GIVEN THE HOT/DRY BOUNDARY LAYER. EXPECTED LACK OF A
LONGER DURATION OF DRY TSTMS WILL PRECLUDE A CRITICAL THREAT AREA.
