...Synopsis...
No fire-weather concerns are anticipated on Friday. Cooler
temperatures and weak surface winds, along with recent wetting
rainfall across much of the U.S. that has dampened remaining dry
fuels, will serve to mitigate any risk of wildfire ignition and
spread.

Valid 221200Z - 231200Z
...NO CRITICAL AREAS...
No changes are needed for the Day 2 Fire Weather Outlook. Broader
fire weather concerns remain absent across the contiguous U.S. as
recent rainfall, cooler temperatures and lack of alignment of
dry/breezy conditions with receptive fuels have mitigated overall
fire danger.

.PREV DISCUSSION... /ISSUED 1251 AM CST Fri Nov 21 2025/
...Synopsis...
No fire-weather concerns are anticipated Saturday. Much of the
Continental U.S. will experience surface high pressure, cooler
temperatures, and weak surface winds, combined with recent wetting
rainfall that has dampened remaining fuels.
U.S. Day 3-8 Fire Weather Outlook
ZCZC SPCFWDD38 ALL
FNUS28 KWNS 212107
Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0307 PM CST Fri Nov 21 2025
Valid 231200Z - 291200Z
...Synopsis...
Limited fire weather concerns are expected across the contiguous
U.S. for the Day 3-8/Sunday-Friday forecast period. An eastward
moving upper-level trough across the Southwest on Day 3/Sunday along
with nascent surface cyclogenesis across the Central Plains should
usher in deeper Gulf moisture from the south, promoting another
widespread precipitation event across much of the southern/central
Plains through Day 4/Monday. The surface cyclone moves into the
Great Lakes/Upper Midwest by midweek, with a trailing cold front and
associated precipitation band affecting much of the eastern U.S.
through Day 6/Wednesday. Dry, post-frontal flow across the Southeast
on Day 7/Thursday could present elevated fire weather concerns
across southern GA/northern FL where drought and patches of dry
fuels remain, although some preceding rainfall on Day 6/Wednesday
would limit a broader threat.
Dry conditions reemerge across CA and much of the Southwest next
week as mid-level riding amplifies into the West. A broad surface
high pressure evolving across the Intermountain West will promote an
increasing offshore pressure gradient across central/southern CA
through much of the week. However, recent widespread rainfall and
unreceptive fuels should limit fire weather concerns across southern
CA next week.
