There are no fire-weather concerns forecast for Sunday. A lack of
dry and windy conditions coupled with cooler temperatures and recent
wetting rainfall will mitigate any threat for wildfire ignition and
spread.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0131 PM CST Sun Nov 23 2025
Valid 241200Z - 251200Z
...NO CRITICAL AREAS...
No changes to the Day 2 Fire Weather Outlook were needed with no
highlights introduced. Relatively dry, post-frontal flow in the wake
of an exiting surface low/trough is expected across western TX
Monday. West/northwest winds of 10-15 mph and relatively humidity
briefly falling to between 15-20% could bring locally elevated fire
weather conditions across the TX Big Bend/Edwards Plateau region
Monday afternoon. However, at least some rainfall preceding the dry
west/northwest flow along with mostly unreceptive fuels should limit
a more significant fire weather threat across western TX. Otherwise,
minimal fire weather concerns will remain across the rest of the
contiguous U.S.

.PREV DISCUSSION... /ISSUED 1246 AM CST Sun Nov 23 2025/
...Synopsis...
No fire-weather concerns are anticipated on Monday due to an overall
lack of overlap of dry/windy conditions with receptive fuels. Cooler
temperatures, weaker surface winds, and recent wetting rainfall will
all serve to reduce the threat for wildfire ignition and spread.
U.S. Day 3-8 Fire Weather Outlook
ZCZC SPCFWDD38 ALL
FNUS28 KWNS 232115
Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0315 PM CST Sun Nov 23 2025
Valid 251200Z - 011200Z
...Synopsis...
A mid-level short wave currently over the Southwest will shift
eastward and deamplify through Day 3/Tuesday while an accompanying
surface cold front will aid in bringing more precipitation to much
of eastern U.S. A strengthening surface cyclone over the Great Lakes
and deepening mid-level trough encompassing the eastern U.S. on Day
4/Thursday, should usher in colder and drier air mass into much of
the region through late week, mitigating fire weather concerns.
Longer term ensemble guidance suggests a deep upper-level trough
evolving across the West over the weekend with subsequent surface
cyclogenesis over the Central Plains supporting the potential for
additional widespread precipitation across the central U.S. Weak
offshore flow across southern CA along with dry conditions under a
ridge aloft are expected Days 3-4/Tuesday-Wednesday. However, recent
expansive precipitation events have limited fuel receptiveness to
wildfire spread across southern CA. Overall, minimal fire weather
concerns across the contiguous U.S. are expected next week.
