VALID 121200Z - 131200Z
SLIGHT EXPANSIONS WERE MADE TO THE LARGER ELEVATED AREA ENCOMPASSING
THE CENTRAL ROCKY MOUNTAINS AND THE SURROUNDING AREAS OF THE
SOUTHEASTERN GREAT BASIN AND CENTRAL HIGH PLAINS. AHEAD OF THE
PREVIOUSLY MENTIONED COLD FRONT DROPPING SOUTH THROUGH THE GREAT
PLAINS, SOUTHWEST/WEST WINDS OF 10-20 MPH WILL COMBINE WITH RHS OF
5-15% ACROSS THE NE PANHANDLE AND ADJACENT PORTIONS OF EASTERN AND
CENTRAL WY TO SUPPORT ELEVATED CONDITIONS AMID CRITICALLY DRY FUELS
(ERCS NEAR THE 90-95TH PERCENTILE). ACROSS SOUTHERN UT, ABOVE NORMAL
TEMPERATURES SUPPORTING DEEP BOUNDARY LAYER MIXING WILL ALSO
CONTRIBUTE TO SLIGHTLY STRONGER WESTERLY WINDS OF 10-20 MPH AMID THE
DRY SURFACE RHS OF 5-10%. THIS WILL ALSO SUPPORT EXPANDED ELEVATED
FIRE WEATHER CONDITIONS FARTHER WEST OF THE PREVIOUSLY DRAWN AREA.
ACROSS THE SNAKE RIVER PLAIN OF ID, ELEVATED CONDITIONS REMAIN ON
TRACK AS PREVIOUSLY FORECAST.

..SYNOPSIS
AS RIDGING BUILDS OVER THE PACIFIC NORTHWEST, BROAD UPPER-LEVEL
TROUGHING WILL EXTEND ACROSS THE UPPER MIDWEST AND GREAT LAKES
REGIONS. A SHORTWAVE TROUGH WILL MOVE INTO THE NORTHERN ROCKIES
FRIDAY AFTERNOON WITH INCREASING MID-LEVEL WESTERLY FLOW USHERING
LOW RH AND GUSTY WINDS THROUGH THE SNAKE RIVER PLAIN. ENHANCED ZONAL
FLOW OVER THE CO ROCKIES AND SOUTH-CENTRAL WY WILL PROMOTE GUSTY
WINDS AND DOWNSLOPE DRYING AMID WARM DAYTIME TEMPERATURES,
CONTINUING A BROADER FIRE WEATHER THREAT WHERE FUELS APPROACH
CRITICAL THRESHOLDS.
...UPPER COLORADO RIVER BASIN, CENTRAL ROCKIES, AND SOUTHERN
WYOMING...
STRONG UPPER-LEVEL WINDS WILL OVERSPREAD THE REGION ON FRIDAY
AFTERNOON, ENCOURAGING CONTINUED DRY AND BREEZY CONDITIONS WHILE
SURFACE TEMPERATURES RISE 10+ DEGREES ABOVE NORMAL UNDER THE
INFLUENCE OF HIGH PRESSURE. SUSTAINED WESTERLY WINDS OF UP TO 15 MPH
AND 10-15% RH ARE EXPECTED TO OVERLAP A DRYING FUELSCAPE, THUS
ELEVATED HIGHLIGHTS HAVE BEEN INTRODUCED. LOCALIZED CRITICAL
CONDITIONS (LESS THAN 10% RH AND 15-20 MPH WINDS) ARE POSSIBLE
ACROSS PORTIONS OF NORTHEASTERN UT AND SOUTHERN WY. HOWEVER, SPARSE
FUELS PRECLUDE CRITICAL HIGHLIGHTS, THOUGH AN UPGRADE MAY BE
CONSIDERED IN FUTURE OUTLOOK CYCLES.
..SNAKE RIVER PLAIN
AHEAD OF AN APPROACHING COLD FRONT, SUSTAINED WESTERLY WINDS OF
10-20 MPH WILL COMBINE WITH 10-15% RH (LOCALLY LOWER) IN THE SNAKE
RIVER PLAIN, SUPPORTIVE OF ELEVATED HIGHLIGHTS. WEEKS OF DRY, WINDY
CONDITIONS AND MINIMAL PRECIPITATION HAS INFLICTED CURING OF FUELS
ACROSS THE REGION, ENHANCING FIRE WEATHER CONCERNS AS ERCS APPROACH
THE 80TH-90TH PERCENTILE ON FRIDAY.
