Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0126 AM CST Fri Nov 13 2026
Valid 131200Z - 141200Z
...NO CRITICAL AREAS...
...Synopsis...
Deep, longwave troughing will remain positioned over the eastern
U.S. today as negatively tilted upper-level troughing moves onshore
across the West, bringing rain and snow to most of the West Coast
and Intermountain West. Cooler, drier air will filter farther south
across the eastern U.S. amid the continued upper troughing as a
surface low departs the Northeast and high pressure builds slowly
southeastward into the Midwest.
...Southeast...
Dry and breezy, post-frontal conditions will continue across much of
the Southeast today. While minimum RH values are forecast in the
25-40% range (locally down to 20% across portions of the ArkLaTex
and lower Mississippi Valley), winds are forecast to remain lighter
than yesterday at 10-15 mph with a few gusts to around 20 mph
possible. Thus, while locally elevated fire weather conditions are
likely, weaker winds and a lack of overlap between elevated winds/RH
and receptive fuels precludes the addition of Elevated highlights.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0127 AM CST Fri Nov 13 2026
Valid 141200Z - 151200Z
...NO CRITICAL AREAS...
...Synopsis...
Deep, longwave upper-level troughing will begin to gradually shift
offshore of the East Coast on Day 2/Saturday as negatively tilted
upper troughing progresses eastward from the Intermountain West
toward the central Rockies/Great Plains and another robust upper
trough approaches the Pacific Northwest. These upper-level features
will continue to bring chances for precipitation to portions of the
Rockies and Pacific Northwest, with rain chances also spreading into
the southern Plains. At the surface, high pressure will remain
positioned across the upper/mid Mississippi Valley, with cooler and
drier conditions continuing across much of the Southeast. While dry
conditions/fuels should be maintained across the Southeast and
mid/lower Mississippi Valley, generally light surface winds are
expected to limit the overall fire weather threat at this time.

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0326 PM CST Thu Nov 12 2026
Valid 141200Z - 201200Z
...Synopsis...
An upper-level trough will gradually exit the East Coast by early
next week as broader ridging shifts into the north-central U.S. and
Canadian Prairies. Surface high pressure along with a period of
prolonged dry conditions and cooler temperatures will settle into
much of the Southeastern U.S. in the wake of the exiting trough. Dry
fuels should be maintained across the region but light winds will
tend to limit a greater fire weather threat through the middle of
next week across the Southeast and mid/lower MS River Valley.
An active troughing pattern will evolve across much of the
Intermountain West as deeper Pacific moisture shifts inland and
associated precipitation subdues fire weather concerns into next
week. The northern Plains and portions of the central Plains should
remain dry through early next week. A mid-level short wave trough
pushes into the southern Plains should bringing widespread rainfall
to the region over the weekend with rainfall amounts tapering off
farther north across the central Plains. Model guidance consensus
suggests a stronger trough ejecting into the central Plains on Day
7/Wednesday which could promote enhanced downslope winds and drying
over the central High Plains. Some uncertainty in the preceding
precipitation event and potential for additional precipitation with
the stronger trough arrival, limits predictability of the fire
weather threat for the central High Plains on Day 7/Wednesday.
