0208 PM CDT TUE AUG 04 2026
VALID 051200Z - 061200Z
AN ELEVATED AREA WAS ADDED FROM SOUTHEAST IDAHO AND NORTHEAST UTAH
INTO SOUTHERN WYOMING AND WESTERN COLORADO. WEST-NORTHWEST SUSTAINED
WINDS OF 10-20 MPH WITH GUSTS OF 20-30 MPH ARE LIKELY AMID MINIMUM
RH OF 5-15%. THERE REMAINS CONCERN THAT STRONGER FLOW ALOFT WILL
SHIFT EAST BEFORE THE AFTERNOON AND THUS LIMIT STRONG WINDS MIXING
TO THE SURFACE. HOWEVER, MOST FORECAST GUIDANCE KEEPS SLIGHTLY
STRONGER FLOW ALOFT NEAR/OVER THE ELEVATED AREA INTO THE AFTERNOON.
ADDITIONALLY, HREF/REFS/NBM JOINT WIND/RH PROBABILITIES SHOW MUCH OF
THE ELEVATED AREA WITH AT LEAST A 50% CHANCE OF HAVING ELEVATED FIRE
WEATHER CONDITIONS DURING THE AFTERNOON INTO THE EVENING, WITH
SWATHS OF AREAS ABOVE 90%.

..SYNOPSIS
UPPER-LEVEL TROUGHING OVER THE NORTH/CENTRAL U.S. WILL GRADUALLY
SHIFT EASTWARD INTO THE GREAT LAKES REGION, WHILE UPPER RIDGING
CONTINUES TO STRENGTHEN AND LIFT NORTHWARD ACROSS THE WESTERN CONUS.
A DRY AIRMASS WILL PERSIST IN THE INTERIOR WEST AMID A VERY DRY
FUELSCAPE, BUT WEAKENING MID/UPPER-LEVEL FLOW AS THE TROUGH DEPARTS
SHOULD LIMIT BROADER SUSTAINED WINDS TO LESS THAN 15 MPH. HOWEVER,
LOCALLY ELEVATED FIRE CONCERNS MAY EMERGE ACROSS SOUTHEAST IDAHO
INTO PORTIONS OF THE COLORADO PLATEAU AND ADJACENT HIGHER ELEVATIONS
WHERE TERRAIN-DRIVEN WINDS COMBINE WITH RH VALUES OF 5-15%. FARTHER
WEST, LOCALLY ELEVATED FIRE WEATHER CONDITIONS ARE EXPECTED AS A
THERMAL TROUGH EXTENDING OUT OF NORTHERN CALIFORNIA INTO WESTERN
OREGON/WASHINGTON PROMOTES HOT, DRY, UNSTABLE, AND LOCALIZED BREEZY
WINDS.
