VALID 021200Z - 031200Z
..PORTIONS OF NORTHERN ROCKIES AND NORTHERN HIGH PLAINS
INCREASING DEEP LAYER SOUTHWESTERLY FLOW WILL AFFECT PORTIONS OF THE
INTERMOUNTAIN WEST INTO THE NORTHERN HIGH PLAINS AS A ROBUST
UPPER-LEVEL TROUGH ENTERS THE NORTHWESTERN CONUS. A ZONE OF DRY,
SOUTHWESTERLY FLOW AHEAD OF COOLER, CLOUDIER CONDITIONS ACROSS THE
PACIFIC NORTHWEST, WILL MANIFEST IN ELEVATED FIRE WEATHER CONCERNS
FOR MUCH OF NORTHEASTERN WY, FAR SOUTHWESTERN SD AND
SOUTHWESTERN/SOUTHERN MT WEDNESDAY. SUSTAINED SOUTHWEST WINDS OF
AROUND 15 MPH AND RELATIVE HUMIDITY OF 15-20% WILL PROMOTE ELEVATED
FIRE WEATHER CONCERNS LATE WEDNESDAY MORNING INTO THE AFTERNOON.
LOCALIZED AND BRIEF CRITICAL FIRE WEATHER CONDITIONS INCLUDING
SUSTAINED WINDS OF 20 MPH AND RH AS LOW AS 10% ARE POSSIBLE IN
FAVORED DOWNSLOPE AREAS, BUT A WIDESPREAD CRITICAL FIRE WEATHER
THREAT IS NOT EXPECTED.
..SOUTHEASTERN NEVADA AND SOUTHWESTERN UTAH
A CORRIDOR OF STRONGER SOUTHWEST WINDS ARE EXPECTED IN SOUTHEASTERN
PORTIONS OF THE GREAT BASIN AS THE UPPER-TROUGH SHIFTS DEEPER INTO
THE NORTHWEST. RH REDUCTIONS TO BELOW 10% BY PEAK AFTERNOON HEATING
ARE LIKELY AMID SOUTHWEST WINDS OF 15-25 MPH. HOWEVER, RECENT
RAINFALL AND ITS MITIGATING EFFECTS ON FUELS PRECLUDES INTRODUCTION
OF HIGHLIGHTS AT THIS TIME.

/ISSUED 0106 AM CDT TUE SEP 01 2026/
..SYNOPSIS
A CORRIDOR OF DRY SOUTHWEST FLOW SOUTHEAST OF THE BROADER
UPPER-LEVEL TROUGH OVER THE NORTHWEST WILL PRESENT FIRE WEATHER
CONCERNS WHERE RECEPTIVE FUELS EXIST ACROSS PORTIONS OF CENTRAL AND
NORTHEASTERN WY, CENTRAL AND SOUTHERN MT, AND THE LOW ELEVATIONS OF
FAR SOUTHWESTERN SD ON DAY 2/WEDNESDAY. A PERSISTENT DEEP LAYER OF
SOUTHWEST FLOW AMID LEE SURFACE TROUGHING OVER THE CENTRAL/NORTHERN
HIGH PLAINS WILL SUPPORT SOUTHWEST SURFACE WINDS OF 15-20 MPH
COINCIDENT WITH AFTERNOON RHS AS LOW AS 10% WITHIN PORTIONS OF THE
DRAWN AREA. LIGHT RAINFALL PRIOR TO THE ONSET OF DRY AND WINDY
CONDITIONS IS NOT ANTICIPATED TO SIGNIFICANTLY IMPACT FUELS
RECEPTIVITY.
STRONG SOUTHWEST WINDS OF 15-25 MPH AND LOW DAYTIME RH WILL ALSO
OCCUR FROM SOUTHERN NV INTO WESTERN UT ON DAY 3/WEDNESDAY. HOWEVER,
RECENT MORE SUBSTANTIAL RAINFALL HAS MUTED FUEL RECEPTIVITY ACROSS
THIS AREA, PRECLUDING ANY DRAWN AREAS.
