DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0302 AM CDT FRI JUN 26 2026
VALID 271200Z - 281200Z
...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF EASTERN
NEVADA...NORTHERN ARIZONA...NORTHWESTERN NEW
MEXICO...SOUTHERN/CENTRAL UTAH...SOUTHERN WYOMING...AND WESTERN
COLORADO...
..SYNOPSIS
A SEASONABLY STRONG MID-LEVEL TROUGH WILL CONTINUE TO DIG INTO THE
WESTERN CONUS ON D2/SATURDAY, WITH AN ATTENDANT MID-LEVEL JET
OVERSPREADING MUCH OF THE UPPER COLORADO RIVER BASIN. THIS WILL
CONTINUE TO SUPPORT A ROBUST FIRE WEATHER PATTERN ACROSS AN
EXPANSIVE PORTION OF THE GREAT BASIN AND SOUTHWEST THROUGH THE
WEEKEND.
..GREAT BASIN/SOUTHWEST
AS THE MID-LEVEL JET ASSOCIATED WITH THE DIGGING MID-LEVEL TROUGH
SHIFTS EASTWARD INTO THE UPPER COLORADO RIVER VALLEY, A CORRIDOR OF
STRONGER, SUSTAINED SURFACE WINDS (25-30 MPH) WILL EXPAND FROM
SOUTHEASTERN NEVADA INTO THE COLORADO PLATEAU AND OVERLAP WITH VERY
LOW RH VALUES OF 10-15%. EXACERBATED BY DRY, WINDY CONDITIONS ON
D1/FRIDAY, FUELS WILL BE VERY RECEPTIVE, WITH ERCS ALREADY NOTED IN
THE 80-90+ PERCENTILES. THESE CONDITIONS WILL PROMOTE AN EXTENDED
PERIOD OF CRITICAL FIRE WEATHER CONDITIONS FROM SOUTHEASTERN NEVADA
INTO THE UPPER COLORADO RIVER BASIN AND SOUTHERN WYOMING. LOCALIZED
EXTREMELY CRITICAL WIND/RH CONDITIONS ARE POSSIBLE, PARTICULARLY
ACROSS SOUTHEASTERN UTAH AND PERHAPS INTO SOUTHWESTERN COLORADO
WHERE LATEST HIGH-RES GUIDANCE SUGGESTS THAT THE BEST OVERLAP OF
SUSTAINED SOUTHWESTERLY WINDS APPROACHING 30 MPH AND VERY LOW RH
NEAR 10% MAY OCCUR. POCKETS OF FUELS IN THIS REGION ARE ALSO NOTED
TO BE AT OR ABOVE THE 95TH PERCENTILE. A BROADER AREA OF ELEVATED
WIND/RH CONDITIONS ARE EXPECTED ACROSS ADJACENT AREAS OF THE GREAT
BASIN/SOUTHWEST WHERE SUSTAINED WINDS OF 15-25 MPH ARE FORECAST TO
OVERLAP DRY FUELS AND RH VALUES OF 10-20%.
THE PRIMARY CHANGE WITH THIS OUTLOOK WAS TO EXPAND THE CRITICAL
HIGHLIGHTS INTO NORTH CENTRAL COLORADO BASED ON THE LATEST HIGH-RES
GUIDANCE. CONSIDERATION WAS GIVEN TO THE ADDITION OF A TARGETED
EXTREMELY CRITICAL AREA; HOWEVER, SOME UNCERTAINTY REMAINS REGARDING
THE DURATION OF OVERLAP BETWEEN SUSTAINED WINDS EXCEEDING 30 MPH AND
RH VALUES DROPPING BELOW 10%. A PORTION OF THE ELEVATED HIGHLIGHTS
WERE ALSO TRIMMED ACROSS CENTRAL WYOMING AND THE FOOTHILLS OF
NORTHERN COLORADO OWING TO RECENT RAINFALL.
