Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0500 PM CDT Mon Jul 07 2025

Valid 091200Z - 151200Z

...Day 3/Wednesday...
Stronger west winds with the arrival of a mid-level short wave
trough and attendant cold front are expected across the Columbia
Basin where fuels remain dry. Although cooler temperatures and
slightly higher humidity arrive with the cold front, sustained west
winds of 15-25 mph will continue to support a fire weather threat
amid dry fuels across the Columbia Basin. A mid-level short wave
trough will translate over a broad ridge situated over the
Southwestern U.S. Collocation of ascent ahead of a mid-level jet max
and antecedent mid-level moisture should support isolated
thunderstorms with limited rainfall across southeastern
OR/southwestern ID on Day 3/Wednesday. The accelerated mid-level
flow on the southern periphery of the aforementioned short wave
along with a deep/well-mixed boundary layer will promote elevated
west-southwest winds across much of the Great Basin and portions of
southern Idaho. The breezy and very dry conditions support at least
a 40% probability for critical fire weather conditions across the
region amid an expected dry fuelscape.

...Day 4/Thursday...
The mid-level short wave edges eastward into the Southern Rockies
bringing elevated west winds to the Intermountain West and great
Four Corners region Day 4/Thursday. A 40% probability for critical
fire weather was introduced into southern UT and northern AZ where
fuels will go under several days of drying through midweek, becoming
more receptive to wildfire spread.

...Day 5-8/Friday-Monday...
Building heat is expected across much of the Western U.S. through
the weekend under an expanding mid-level ridge over southern CA
which will promote a limited wind threat across the region. Monsoon
moisture and associated thunderstorms will remain confined to
southern AZ and NM through the weekend.
