.PREV DISCUSSION... /ISSUED 1246 AM CST Sun Nov 23 2025/
...Synopsis...
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.
..Williams.. 11/23/2025
.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

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.
