Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1122 PM CST Tue Nov 10 2026
Valid 111200Z - 121200Z
...NO CRITICAL AREAS...
...Synopsis...
The upper-level flow over the CONUS will continue to amplify with
ridging over the Intermountain West and troughing over portions of
the central/eastern US. A surface cyclone will strengthen and track
east-southeast across the Midwest into the Upper Ohio Valley. Drier
pre-frontal conditions are likely across portions of the southern
Appalachians into Georgia and South Carolina. However, there will
likely be limited overlap of moderately receptive fuels and elevated
winds/RH, thus precluding introducing any risk areas at this time.
Drier post-frontal northwesterly flow is expected on the Plains as
well, but the strongest winds (15-20 mph sustained) are likely to be
displaced from the lowest RH (20-25%), with limited receptive fuels.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1136 PM CST Tue Nov 10 2026
Valid 121200Z - 131200Z
...NO CRITICAL AREAS...
...Synopsis...
The upper-level pattern over the CONUS will remain amplified on Day
2/Thursday 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 moves off the Mid-Atlantic coast.
Dry and breezy post-frontal conditions will develop across portions
of the Southeast, and locally elevated conditions are likely from
the Lower Mississippi Valley into portions of the Carolinas.
Northwest-west sustained winds of 10-18 mph amid minimum RH of
25-40% are forecast from the Lower Mississippi Valley extending east
through the Deep South into the Carolinas. Forecast burning index
values may exceed the 80th percentile and approach the 90th
percentile in portions of this area. If the forecast continues to
trend towards little to no pre-frontal rainfall and better alignment
of dry/breezy conditions with modestly receptive fuels, an elevated
area may be warranted. Additionally, this is the type of scenario
where forecast guidance can under predict winds and over predict RH.

ZCZC SPCFWDD38 ALL
FNUS28 KWNS 092121
Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0321 PM CST Mon Nov 09 2026
Valid 111200Z - 171200Z
...Synopsis...
A highly amplified flow pattern develops across the CONUS through
late this week. Ridging across the western U.S. will contribute to
above normal temperatures and dry conditions through Day 5/Friday
under a relatively light wind regime. Farther east, broad troughing
will envelop the eastern U.S. with a strong surface low moving into
the Mid Atlantic as a trailing cold front sweeps towards the Gulf
and Atlantic coasts. A post-frontal air mass will filter into the
Southeast on Day 4-5/Thursday-Friday bringing dry, offshore flow to
the Deep South. Preceding precipitation in the Day 3/Wednesday into
Day 4/Thursday time frame could mitigate impact from the enhanced
north/northwesterly winds and lower RH.
An upper-level trough is expected to enter the western U.S. this
weekend bringing rain and high elevation snow to much of the
Intermountain West, alleviating fire weather concerns across the
region into early next week. Warm and dry conditions across the
central and northern High Plains ahead of the trough should allow
for drier fuels to develop into the weekend but lack of overlapping
dry and breezy conditions should limit the fire weather threat.
