Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1148 PM CST Mon Nov 09 2026
Valid 101200Z - 111200Z
...NO CRITICAL AREAS...
...Synopsis...
An upper-level shortwave trough will track east-southeast across the
northern Plains into the Midwest with an associated deepening
surface cyclone. Strong northwest flow aloft will trail the surface
cold front stretching from central/eastern Montana into northeast
Colorado and northwest Kansas. The west-northwest flow favors
downslope winds and drying yielding 15-25 mph sustained winds amid
minimum RH of 15-30% across southeast Wyoming into the Nebraska
Panhandle and northeast Colorado. However, according to forecast
fire danger, ERC and 10/100-hour dead fuel moisture values are
generally around the 50th percentile, with forecast BI values
between the 50-75th percentiles. While elevated to locally critical
wind/RH criteria will likely be satisfied, limited fuel
receptiveness will mitigate the fire risk.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1149 PM CST Mon Nov 09 2026
Valid 111200Z - 121200Z
...NO CRITICAL AREAS...
...Synopsis...
The upper-level flow over the CONUS amplifies on Day 2/Wednesday
with ridging over the Intermountain West and troughing across
portions of central/eastern portions of the CONUS. A surface cyclone
will strengthen and track east-southeast across the Midwest into the
Ohio Valley. Drier post-frontal flow will develop on much of the
Plains. However, the stronger winds are likely to be displaced from
the lowest RH, and fuels are not particularly receptive on the
Plains. 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.

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.
