Day 1 Fire Weather Outlook

1123 AM CDT Mon Jun 22 2026

Valid 221700Z - 231200Z

A broad area of elevated fire weather highlights remains across much
of the lower CO River Basin and adjacent Four Corners region.
Critically dry and breezy conditions will develop under a building
upper ridge, with current RH across much of the Southwestern U.S.
already in the single digits following poor overnight recoveries.
Sustained southwest winds of 10-15 mph, very low RH and dry fuels
are still expected for several hours during peak afternoon heating.
Elevated highlights were expanded northward into portions of
southeastern NV and southwestern UT where sustained south to
southwest winds of around 15 mph could prove impactful to existing
active wildfires.

...Synopsis...
A mid-level ridge will begin building over the Interior West as
upper troughing takes shape over the eastern U.S. today. An embedded
impulse will overspread the central Rockies, encouraging surface
trough development over the Great Basin, where dry and breezy
conditions are expected through the afternoon. Fifteen (15) mph
sustained west-southwesterly surface winds and 10-15 percent RH will
overspread dry fuels across the southern Great Basin into the Four
Corners, warranting the continuation of Elevated highlights. Dry and
breezy conditions will also occur across the Snake River Plain in
southern Idaho due to channeled flow. Fifteen to twenty (15-20) mph
west-southwesterly surface winds will overlap with 10-15 percent RH,
with Elevated highlights continued here as well.
