...Synopsis...
Fire weather concerns are expected to remain low across the CONUS
today. A series of shortwaves will bring widespread precipitation
across the central/northern Rockies into the central Plains and
upper Midwest. Warm and dry conditions will persist across the
eastern US amid high pressure. Fuels are near the 90-95th percentile
across portions of the lower Mississippi River Basin and adjacent
ArkLaTex region amid severe/extreme drought. Though afternoon
relative humidity will drop near 25%, good overnight recoveries and
generally light winds will keep fire concerns low.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0147 AM CDT Mon Oct 26 2026
Valid 271200Z - 281200Z
...NO CRITICAL AREAS...
...Synopsis...
Fire weather concerns will remain low on D2/Tuesday. A mid-level
trough will bring westerly flow across the northern/central Rockies.
Lee troughing will increase across portions of northeastern Wyoming
and southeastern Montana. Though windy conditions are forecast,
fuels across the region are marginal with limited RH reductions and
cooler temperatures expected. This should mitigate a broader fire
weather threat across northeastern Wyoming and southern Montana.

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0444 PM CDT Sun Oct 25 2026
Valid 271200Z - 021200Z
...Synopsis...
A series of mid-level short wave troughs will eject northeastward
into the Central Plains and Upper Midwest through Day 5/Thursday,
supporting areas of precipitation across the Plains towards the
Great Lakes through midweek. A strong mid-level jet stretching from
the Great Basin to the Northern Plains will couple with an evolving
surface trough in eastern MT to support enhanced westerly winds
across portions of eastern/northeastern WY Day 3/Tuesday. However,
marginal fuels, limited RH reductions and cooler temperatures should
mitigate a broader fire weather threat across WY.
A broader trough pattern with an increasing southwesterly flow
component returns across the western U.S. through the end of the
week. Ridging will likely remain in place across the eastern U.S.
promoting persistent dry and warm conditions across much of the Deep
South. Fuels are driest across the lower MS River Basin but light
surface winds will tend to limit significant fire weather concerns
through the week.
