Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0322 PM CDT Tue Sep 02 2025

Valid 041200Z - 101200Z

Fire weather potential appears limited across the country for the
extended period. Medium to long-range guidance continues to show a
gradual amplification of an upper wave over the central CONUS
through late week with an unseasonably strong frontal intrusion into
the Plains and Midwest. This will result in widespread below-normal
temperatures and rain chances, though windy conditions will likely
manifest across portions of the northern Plains on D3/Thursday.
Across the West, persistent upper ridging will maintain warm and dry
conditions across the Great Basin and Pacific Northwest. Weak
gradient winds will mitigate most fire weather concerns through the
remainder of the week. A gradual breakdown of the upper ridge will
likely usher in cooler conditions for parts of the Northwest by
early next week along with scattered rain chances.

...D3/Thursday - Northern Plains...
Medium-range guidance shows strong consensus in 20-25 mph winds
developing within a post-frontal air mass across eastern MT into the
western Dakotas on Thursday afternoon. However, an influx of cooler
air is expected to modulate RH reductions with most
solutions/ensemble guidance suggesting RH values may fall into the
25-35% range. These marginal RH reductions, along with modest fuel
dryness, should limit the overall fire weather threat, though a
wind-driven concern could materialize if RH trends lower than
anticipated and finer fuels can adequately dry.
