Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0147 AM CDT Mon Oct 12 2026
Valid 121200Z - 131200Z
...NO CRITICAL AREAS...
...Synopsis...
A closed mid-level low will migrate slowly southward across the
western Great Basin today, with strong southwesterly flow aloft
extending from the Southwest into the central Great Plains. Coupled
with a remnant subtropical moisture plume, this will continue to
favor chances for rainfall and higher elevation snowfall across much
of the Intermountain West and northern Plains, which will largely
suppress fire weather concerns across the West. Farther east, above
normal temperatures and dry conditions will continue across portions
of the lower Mississippi River Valley and Midwest, but the lack of a
stronger surface pressure gradient and resultant limited sustained
wind speeds are expected to largely temper fire weather concerns.
...Central High Plains...
Strong southwesterly flow aloft (50-60 kts at the nose of a
prominent 500 mb jet) will overspread the central Rockies/High
Plains today, aiding in modest strengthening of a lee surface low
across the central Plains. This will foster enhanced
west-southwesterly surface winds of 15-25 mph across portions of the
central High Plains from northeastern New Mexico into east-central
Colorado, western Kansas, and adjacent portions of the TX/OK
Panhandles. Downslope warming/drying will also aid in RH values
falling to 20-25% (locally to 15% across northeastern/east-central
Colorado, northwestern Kansas, and southwestern Nebraska). Given
these factors, locally elevated fire weather conditions are likely
to manifest this afternoon, but generally marginal fuel
receptiveness across this region precludes a broader fire weather
threat at this time.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0149 AM CDT Mon Oct 12 2026
Valid 131200Z - 141200Z
...NO CRITICAL AREAS...
...Synopsis...
A closed mid-level low will progress slowly eastward across the
Intermountain West on D2/Tuesday, with strong southwesterly flow
aloft persisting from the southern Rockies into the central Great
Plains and Midwest. This will help maintain a lee surface low across
the central Plains, with a corridor of stronger southwesterly
surface winds of 15-25 mph forecast from eastern New Mexico into the
western TX/OK Panhandles, southeastern Colorado, and southwestern
Kansas. Downslope drying will also foster RH reductions to around
20% across this region, but poor fuel receptiveness (ERCs generally
below the 50th to 60th percentiles) will temper overall fire weather
concerns.
Farther east, upper-level ridging will remain in place across the
western Gulf Coast and lower Mississippi River Valley. Concurrently,
a surface frontal system will progress southward across the central
Plains and Midwest, bringing chances for precipitation. Coupled with
lingering chances for rainfall and higher elevation snowfall across
portions of the West, widespread fire weather concerns will continue
to be largely suppressed across much of the U.S.

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0432 PM CDT Sun Oct 11 2026
Valid 131200Z - 191200Z
...Synopsis...
An upper-level low and associated precipitation across the western
U.S. will move into the Upper Midwest by Day 5/Thursday and merge
with an amplifying mid-upper trough evolving over the Great Lakes
and Northeast by Day 7/Saturday. Ridging will build back over the
western U.S., supporting a warming and drying trend over the region
through the weekend. An offshore wind event is likely across
southern CA beginning Day 5/Thursday as broad surface high pressure
moves into the central U.S. coupled with a potential cut off low
setting up over Baja California. However, recent widespread
precipitation across much of southern CA should have a lingering,
mitigating impact on fuels late into the week where stronger
offshore winds are more likely. This should temper fire weather
concerns for this event. Farther east, the lower MS River Valley
will remain mostly dry as ridging persists over the Deep South
through midweek promoting a receptive fuelscape. A dry, continental
air mass settles into the eastern CONUS Days 6-7/Friday-Saturday.
The resultant post-frontal northerly flow and lack of preceding
rainfall could bring fire weather concerns back into the lower MS
River Valley on Day 6/Friday although some uncertainty in forecast
wind magnitude precludes the introduction of critical probabilities
at this time.
