Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1137 PM CST Wed Nov 11 2026
Valid 121200Z - 131200Z
...Synopsis...
The upper-level pattern over the CONUS will remain amplified with a
deep trough over the eastern US, ridging over the Intermountain
West, and troughing moving onto West Coast. A cold front will sweep
southeast through the Southeast as a surface cyclone tracks
northeast off the Mid-Atlantic Coast, with a secondary cold front
moving into the Southeast and southern Plains as well.
Post-frontal dry and breezy conditions are expected across portions
of the Southeast, with elevated to locally critical conditions
extending from southwest Georgia into southeast North Carolina.
West-southwest winds will turn west-northwest behind the afternoon
frontal passage with sustained winds of 10-20 mph and wind gusts of
20-30 mph. RH will drop to 25-40% behind the front coinciding with
peak heating and little to no cloud cover. Northwest sustained winds
of 8-15 mph and minimum RH of 20-35% will likely lead to locally
elevated conditions across southern/central Alabama, Mississippi,
and into portions of Louisiana, Arkansas, and east Texas.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1140 PM CST Wed Nov 11 2026
Valid 131200Z - 141200Z
...NO CRITICAL AREAS...
...Synopsis...
A broad, deep trough will remain over the eastern US with multiple
upper lows moving onto the West Coast on Day 2/Friday. Negatively
tilted upper-level troughing will move over the West bringing rain
and snow to most of the West Coast and into the Intermountain West.
Colder, drier air will filter farther south across the eastern US
amid the continued upper-level troughing.
Dry and breezy post-frontal conditions will continue across the
Southeast on Day 2/Friday. Winds will be lighter than Day
1/Thursday, although northwest-north sustained winds of 8-15 mph and
gusts to around 20 mph remain likely. Minimum RH will once again
range from 25-40% across the region with the potential to drop to
around 20% in/around the ArkLaTex area. Locally elevated conditions
are likely, but with a forecast of weaker winds and lack of overlap
of elevated winds/RH and receptive fuels, an Elevated area was not
introduced.

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0336 PM CST Wed Nov 11 2026
Valid 131200Z - 191200Z
...Synopsis...
A prominent ridge over the central U.S. will begin to weaken as a
broad upper trough pushes into the western U.S. The trough will
usher in deeper Pacific moisture and resultant precipitation for
much of the Intermountain West through the weekend, although
portions of the northern Rockies and Northern Plains should remain
dry into early next week.
Surface high pressure settling into the eastern U.S. will keep
deeper Gulf moisture offshore allowing dry conditions to evolve
across the Deep South. Preceding rainfall across portions of the
Southeast leading up to Day 3/Friday along with cooler temperatures
in a post-frontal environment, could mitigate a broader fire weather
threat across portions of AL/GA/SC Friday despite northwest winds of
10-15 mph amid lower daytime RH and marginal fuels. Although dry
conditions will evolve across the Deep South with daytime RH as low
as 25% in areas, relaxing surface pressure gradients yielding
reduced wind speeds should subdue the overall fire weather threat
heading into next week.
