U.S. Day 1 Fire Weather Outlook

Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1042 AM CST Sat Nov 22 2025
Valid 221700Z - 231200Z
...NO CRITICAL AREAS...
No changes needed to the Day 1 Fire Weather Outlook with limited
fire weather concerns across CONUS. Minimal rainfall over the past
several days has enabled marginally dry fuels to persist across west
TX. Surface high pressure in the wake of a cold front will be
centered over OK through the day supporting a dry,
easterly/southeasterly flow across west TX through the afternoon.
Although dry, relative humidity remaining above 15% combined with
wind speeds of less than 15 mph through the afternoon, will limit a
broader fire weather threat.

.PREV DISCUSSION... /ISSUED 1257 AM CST Sat Nov 22 2025/
...Synopsis...
No fire-weather concerns are anticipated Saturday.
With recent widespread wetting rainfall, cooler temperatures, and
generally weak surface winds, conditions supporting wildfire
ignition and spread will largely be absent.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0131 PM CST Sat Nov 22 2025
Valid 231200Z - 241200Z
...NO CRITICAL AREAS...
No changes needed to the Day 2 Fire Weather Outlook with minimal to
no overlap of dry/breezy conditions and receptive fuels supportive
of rapid fire spread expected across the contiguous U.S. Please see
previous discussion.
..Williams.. 11/22/2025
.PREV DISCUSSION... /ISSUED 1258 AM CST Sat Nov 22 2025/
...Synopsis...
There are no fire-weather concerns anticipated for Sunday. A
progressive trough will bring precipitation from the southern
Rockies into the southern Great Plains, while the rest of the
Continental U.S. will experience cooler temperatures and weak
surface winds, limiting the potential for wildfire ignition and
spread.
U.S. Day 3-8 Fire Weather Outlook
ZCZC SPCFWDD38 ALL
FNUS28 KWNS 222049
Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0249 PM CST Sat Nov 22 2025
Valid 241200Z - 301200Z
...Days 3-6/Monday-Thursday...
A mid-level wave and attendant surface trough/frontal features will
support showers and thunderstorms across the southern/central Plains
on Day 3/Monday, with precipitation expanding and moving into the
lower MS River Valley and OH River Valley by Day 4/Tuesday. A strong
cold front extending southwestward from a deepening surface low in
the Upper Midwest should sweep across much of the eastern U.S.
midweek, reaching the Atlantic Coast late Day 5/Wednesday period. A
dry, post-frontal flow regime could overlap with pockets of dry
fuels across southern GA, northern FL and the Carolinas on Day
6/Thursday, but some preceding rainfall associated with the frontal
passage should mitigate a more significant fire weather threat
across the Southeast. The lower confidence in spatial distribution
of expected rainfall and marginal fuel environment precludes
introduction of critical probabilities at this time.
...Days 6-8/Friday-Saturday...
A descending upper-level trough into the western U.S. and subsequent
lee cyclogenesis across the central/southern Plains could provide a
supportive environment for elevated winds and dry conditions across
the southern High Plains closer to Day 8/Saturday. However,
uncertainty in state of fuels from preceding rainfall through the
Day 2-3/Sunday-Monday period reduces predictability of critical fire
weather conditions late next week.
