Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0454 PM CDT Wed Sep 03 2025

Valid 051200Z - 111200Z

...Day 3-6/Friday - Pacific Northwest...
A mid-level, negatively tilted trough moving into the northern
CA/southern OR region on Day 3/Friday will usher in a more favorable
convective environment with increasing vertical shear and
instability supportive of thunderstorms across much of OR. However,
some uncertainty exists in magnitude of sub-cloud moisture content
which could bring more wetting rain cores to the area in conjunction
with cooling temperatures and higher relative humidity values as the
upper-level trough translates eastward through the weekend. The
parent Pacific low is expected to bring much cooler temperatures
along with wetting rains to much of the Pacific Northwest beginning
Day 5/Sunday, mitigating fire weather concerns through late next
week.

...Day 3-8/Friday-Wednesday - Eastern CONUS...
A broad upper-low will usher in a cold front and subsequent cooler
air mass into much of the eastern U.S. Day 3/Friday through early
next week. Injection of tropical moisture from the remnants of
Hurricane Lorena into the Southwest through Day 4/Saturday will
support wetting rains along the cold front across portions of the
Southern Plains and Deep south early next week, reducing fire
weather concerns.
