Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1024 AM CST Sun Nov 08 2026
Valid 081700Z - 091200Z
...NO CRITICAL AREAS...
Lingering offshore flow across southern CA will promote localized
corridors of east-northeast winds of 10-15 mph with gusts
approaching 30 mph through the morning hours. Relaxing offshore
pressure gradients through this afternoon will translate to lighter
winds overall and allow at least a temporary intrusion of a marine
influenced air mass along coastal areas. Although inland afternoon
RH in the 15-20% is expected, the diminishing winds and marginal
fuels will limit broader fire weather concerns for today.

.PREV DISCUSSION... /ISSUED 1135 PM CST Sat Nov 07 2026/
...Synopsis...
No fire-weather highlights are forecast for today, with much of the
CONUS characterized by unreceptive fuels owing to recent
precipitation. Some portions of the southern and central Appalachian
Mountains are drier than normal, but wind and relative humidity will
not reach Elevated criteria. Portions of the Great Lakes into
western New York will experience 15-20 MPH gusts as a cold front
progresses southeastward out of the Great Lakes, but relative
humidity is not forecast to reach Elevated criteria.

Day 2 Fire Weather Outlook

Fire weather concerns will remain low for D2/Monday across the
contiguous U.S. Please see previous discussion for more details.

.PREV DISCUSSION... /ISSUED 1136 PM CST Sat Nov 07 2026/
...Synopsis...
No fire-weather highlights are forecast for Monday owing to
generally unreceptive fuels from recent rainfall and cooler
conditions. Some prefrontal dry conditions could materialize across
portions of the Southern and Central Great Plains, but winds are
forecast to remain subdued with gusts of 10-15 MPH due to a weak
surface pressure gradient.
U.S. Day 3-8 Fire Weather Outlook

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0335 PM CST Sun Nov 08 2026
Valid 101200Z - 161200Z
...Synopsis...
An increasingly amplified upper ridge is expected to evolve across
the Intermountain West through the midweek while deeper troughing
begins to envelop much of the eastern U.S. An embedded mid-level
short wave and associated jet streak shift into the northern Plains
on Day 3/Tuesday while a related surface trough deepens over the
Dakotas. Dry west/northwest post-frontal flow in the wake of the low
will impact portions of southeastern WY and northeastern CO but a
muted fuelscape should mitigate the fire weather threat. Above
normal temperatures and dry conditions under the building ridge are
expected across the Intermountain West but absence of stronger winds
and marginal fuel conditions should limit fire weather concerns at
least through Day 5/Thursday. Lee-side troughing reemerges across
the central/northern High Plains Days 6-7/Friday-Saturday as the
upper ridge begins to break down. This could usher in stronger,
downslope enhanced winds into southern/eastern WY but expected
seasonable fuel conditions (ERCs in the 50-60th percentile) should
moderate these potential fire weather impacts.
Farther east, a dry, post-frontal wind event is possible across the
Southeast beginning Day 5/Thursday and lasting through Day
7/Saturday as a strengthening surface low moves from the Ohio River
Valley into New England. Uncertainty in precipitation distribution
associated with the front prior to the onset of north/northwest flow
introduces some predictability challenges in terms of future fuel
receptiveness. This region will be watched closely for future
introduction of critical probabilities in subsequent outlooks.
