...Synopsis...
Across the Interior West, westerly flow aloft will gradually
transition to southwesterly as a mid-level trough amplifies over the
Pacific Northwest. Resultant increasing cloud cover across much of
the western CONUS, lighter prevailing winds, and a marginal fuel
environment will limit fire weather concerns. Upper ridging will
continue across the Southeast with surface high pressure remaining
fixed over the eastern CONUS, allowing warm and dry conditions to
prevail. A lack of strong wind where fuels are available to burn,
mainly across the lower MS River Valley and southern Appalachians,
will preclude any significant fire weather threat today.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0131 PM CDT Thu Oct 29 2026
Valid 301200Z - 311200Z
...NO CRITICAL AREAS...
No changes are necessary from the previous Day 2/Friday outlook
issuance. With recent and forecast widespread precipitation across
several regions of the CONUS, remaining areas with the driest
vegetation (especially across portions of the South) will see
downward trends in fire danger.

...Synopsis...
Fire weather concerns will remain low on Day 2/Friday. The western
half of the CONUS will be categorized by amplified upper troughing,
while a mid-level shortwave trough and entrained tropical remnants
bring precipitation to the central/southern Plains. Upper ridging
will continue for one more day across the Southeast, but departing
surface high pressure and the lifting shortwave trough will allow
moisture to gradually permeate the lower MS River Valley where the
driest fuels exist.
U.S. Day 3-8 Fire Weather Outlook
ZCZC SPCFWDD38 ALL
FNUS28 KWNS 282132
Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0432 PM CDT Wed Oct 28 2026
Valid 301200Z - 051200Z
A high amplitude trough will remain over the Pacific Northwest
through at least Day 4/Saturday before nudging eastward, leaving
much of the western third of the CONUS under increased cloud cover,
below-normal temperatures, and periodic precipitation in the
meantime. Farther east, a ridge building over the central CONUS will
begin to transit eastward ahead of the aforementioned trough,
promoting above-normal temperatures over and east of the Great
Plains. Meanwhile, a shortwave trough is expected to pass through
the Southwest and the southern Plains on Day 3/Friday and Day
4/Saturday. As the large trough over the northwestern CONUS begins
to move eastward, it will drag with it cooler-than-normal
temperatures and another round of widespread precipitation across
much of the CONUS early next week. This will drop ERCs across the
board even lower headed into next week.
One area likely to experience little to no rainfall accumulation
through Day 6/Monday will be central/southern OR and northern CA.
However, given the recent and forecast cool and wet conditions over
the western CONUS, areas most likely to experience northerly surface
winds combined with low RHs also have ERCs at or below their 50th
percentile. Areas with the driest antecedent conditions (generally
over the lower MS River corridor) are anticipated to receive
beneficial precipitation. Thus, any threat of significant fire
weather remains low and will trend even lower by next week.
