...Synopsis...
The first in a series of mid-level troughs will eject into the
Plains states as a second mid-level trough impinges on the West
Coast today. Seasonably moist conditions are likely across much of
the Interior West, with scattered to numerous thunderstorms likely
across the Rockies in association with the first upper trough. The
current thinking is that primarily wetting rains may accompany most
thunderstorms across the Rockies, resulting in the continued
dampening of fuels. As such, no fire weather highlights have been
introduced.

...Synopsis...
A mid-level trough will traverse the Plains states as a second
mid-level trough progresses toward the northern Rockies tomorrow
(Sunday). Upper support with the western upper trough will encourage
scattered thunderstorm development across portions of the Northern
Rockies. Furthermore, breezy but marginally dry surface conditions
are also expected across the Great Basin. However, fuel
receptiveness for wildfire spread across both regions is expected to
be relatively poor, with fire weather highlights withheld.

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0436 PM CDT Sat Sep 13 2025
Valid 151200Z - 211200Z
...Synopsis...
By early next week, two mid-level shortwave troughs over the
northern Great Plains and northern Rockies will phase resulting in a
positively tilted trough there. An increasing mid level height
gradient is expected near the base of this feature over the central
Rockies, while surface pressure falls and an increasing pressure
gradient over the northern Plains promote breezy southerlies from
eastern NE to MN. Farther east by mid week, a narrow mid to
upper-level ridge over the Great Lakes will begin to break down as
the aforementioned trough deepens and digs southward over the
Plains. Shortwave ridging, however, will likely continue through
D6/Thursday over already receptive fuels from the MS Valley
northeastward into the OH Valley. A mid to upper-level ridge will
also return to CA and the Southwest by this time. Overall,
considering modest wind speeds across most of the CONUS throughout
the extended forecast (the exception being D3/Monday), the
combined/total fire weather environment is expected to remain low.
...Snake River Plain and southern WY...
Similar to Sunday, localized breezy westerly winds are anticipated
across this area D3/Monday. Relatively higher minimum RH and
unreceptive fuels should limit the fire spread potential, and low
critical probabilities are not warranted.
