Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0459 PM CDT Tue Oct 07 2025

Valid 091200Z - 151200Z

...Days 3-4/Thursday-Friday...
An upper-level low entering the Pacific Northwest later this week
will promote increasing onshore flow across coastal WA/OR and
northern CA, ushering in a cooler/more moist marine air mass. A
northward surge of atmospheric moisture from hurricane Priscilla
into the southwestern U.S. ahead of the upper-level trough will
support showers and thunderstorms across portions of the Southwest
and Colorado River Basin Thursday and Friday, mitigating fire
weather concerns. South to southwest pre-frontal winds across
northeastern CA/southern OR between are expected Thursday/Friday but
alignment  with sufficiently dry conditions and receptive fuels is
unlikely.

...Days 5-6/Saturday-Sunday...
A deepening surface trough across the central and northern High
Plains as the upper-level trough across the western U.S. moves into
the Northern Rockies will promote increasing southerly flow across
the Plains over the weekend. A dry, continental air mass ushered
into the eastern U.S. in the Day 2-3/Wednesday-Thursday period will
scour out deeper moisture across the Southeast, limiting Gulf
moisture return for portions of the southern Plains late this week.
Fuels are becoming increasingly dry across portions of TX and OK as
recent rainfall deficits and warm temperatures have aided in
drying/curing fuels. Primarily dry conditions preceding the increase
in southerly winds across the southern Plains will further prime
fuels for increased wildfire spread potential. A 40% probability of
critical fire weather conditions was introduced for portions of
TX/OK for Day 5-6/Saturday-Sunday to cover this threat.

...Days 7-8/Monday-Tuesday...
Troughing across the West is expected to persist, maintaining cooler
temperatures, cloud cover and opportunities for rain and higher
elevation snow across the Northwest, reducing fire weather concerns.
Increasing Gulf moisture should mitigate fire weather threats early
next week across the southern Plains within a continued
south/southwest wind regime.
