DAY 1 FIRE WEATHER OUTLOOK

1100 AM CDT THU JUN 04 2026
VALID 041700Z - 051200Z
ONLY MINOR ADJUSTMENTS WERE MADE TO ELEVATED AREA BASED ON THE
LATEST FORECAST GUIDANCE. WHILE THERE MAY BE LOCALIZED AREAS
REMAINING BELOW ELEVATED WIND CRITERIA THIS AFTERNOON, THEY WILL BE
THE EXCEPTION, NOT THE RULE. MUCH OF THE STRONGEST WINDS COMBINED
WITH THE LOWEST RHS WILL OCCUR BEHIND THE FRONT, PROMOTING EASTWARD
FIRE SPREAD THIS AFTERNOON ACROSS THE HIGHLIGHTED AREA. IT'S NOT OUT
OF THE QUESTION THAT SOME NORTHERN PORTIONS OF THE DRAWN AREA COULD
EXPERIENCE BRIEF LOCALIZED CRITICAL WIND/RH, BUT FUELS ALSO APPEAR
SLIGHTLY LESS CRITICALLY DRY THERE. ADDITIONALLY, GIVEN THE
ABOVE-NORMAL TEMPERATURES, WELL-MIXED BOUNDARY LAYER, AND RESULTANT
DRY SURFACE AIR, EXPECT BURN PERIODS TO BECOME INCREASINGLY LONGER
OVER MUCH OF THE HIGHLIGHTED AND SURROUNDING AREAS STARTING
TODAY/TONIGHT.

..SYNOPSIS
AHEAD OF A SLOW APPROACHING DEEP UPPER LOW CURRENTLY OFFSHORE THE
BRITISH COLUMBIA COAST, ZONAL FLOW WILL OVERSPREAD THE NORTHWEST
THROUGH THE UPPER MIDWEST. MULTIPLE EMBEDDED PERTURBATIONS WITHIN
THE DOWNSTREAM FLOW WILL ENCOURAGE ADDITIONAL PRECIPITATION ACROSS
PORTIONS OF MINNESOTA AND WISCONSIN, BRINGING SOME RELIEF TO A
RECENTLY RECEPTIVE FUELSCAPE. UPPER RIDGING WILL CONTINUE TO FLATTEN
OVER THE GREAT LAKES REGION, STEERING SURFACE HIGH PRESSURE ATOP THE
SOUTHEAST AND INITIATING A GRADUAL WARMING TREND INTO THE WEEKEND.
A WEAK, DRY COLD FRONT WILL STALL ACROSS THE GREAT BASIN TODAY,
EXTENDING FROM SOUTHWESTERN WYOMING INTO CENTRAL NEVADA. BEHIND THE
FRONT, SUSTAINED WESTERLY WINDS OF 10-20 MPH (GUSTS UP TO 35 MPH IN
THE UPPER COLORADO WESTERN SLOPE INTO THE WYOMING BASIN) ARE
EXPECTED THROUGH MUCH OF THE AFTERNOON HOURS. HOT AND VERY DRY
(5-15% MINIMUM RHS) CONDITIONS SUPPORTIVE OF DEEP BOUNDARY LAYER
MIXING UP TO 450 MB WILL BE IN PLACE OVER MUCH OF THE SOUTHWEST,
GREAT BASIN, AND CENTRAL ROCKY MOUNTAIN REGIONS. ELEVATED FIRE
WEATHER HIGHLIGHTS HAVE BEEN MAINTAINED WHERE THIS COMBINATION OF
WIND/RH AMID RECEPTIVE FUEL CONDITIONS WILL SUPPORT A LIMITED FIRE
WEATHER RISK THIS AFTERNOON. GIVEN THE RIGHT ALIGNMENT OF WIND, RH,
AND VERY DRY FUELS POSSIBLE WITHIN LOCALIZED PORTIONS OF THE DRAWN
AREA, CRITICAL THRESHOLDS COULD BE BRIEFLY ACHIEVED.
