...NO CRITICAL AREAS...
...Synopsis...
The upper trough in the northern Plains/Upper Midwest will amplify
today as it moves toward the Mid-Atlantic/Northeast. This will help
drive colder air into the Plains. Ahead of the colder air, a modest
surface low will develop and evolve southward within the central and
southern High Plains. There will be brief potential for dry/breezy
conditions that may approach elevated criteria locally. Given the
short duration of these conditions and the generally unreceptive
fuels, no highlights are warranted.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1125 PM CST Fri Dec 12 2025
Valid 141200Z - 151200Z
...NO CRITICAL AREAS...
...Synopsis...
The upper trough will move through the Mid-Atlantic/Northeast on
Sunday into Monday morning. The upper ridge in the West will expand
into the Plains. A surface high pressure system will move
southeastward and a cold front will move through much of the Gulf.
Locally dry and windy conditions are possible in eastern Wyoming.
Poor fuel receptiveness will preclude much in the way of fire
weather concerns. Though temperatures will be cool/cold in the
Southeast, gusty northerly winds and modest RH reductions will be
possible. Recent precipitation in the past week has left fuel
receptiveness marginal at best. This, along with the marginal
temperatures, should preclude fire weather concerns.

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0307 PM CST Fri Dec 12 2025
Valid 141200Z - 201200Z
The potential for critical fire weather conditions remains limited
across the country for much of the extended period, though localized
concerns may emerge along portions of the High Plains during the
middle of the upcoming work week. Long-range ensemble and cluster
guidance shows strong agreement in the continuation of broad-scale
northwesterly flow aloft over the CONUS through the weekend with a
shift to a more zonal flow regime through the end of next week. This
upper-level regime will favor cool conditions with sporadic
precipitation chances from the Pacific Northwest into the northern
Plains, Midwest, and Northeast. Much of the Southwest and southern
Plains will likely see very limited rain/snow potential through the
next 8 days with above-normal temperatures possible.
...D6/Wed - Central to southern High Plains...
Latest ensemble guidance shows strong consensus in dry conditions
through the end of the upcoming work week for central and southern
High Plains. After a brief cool down this weekend, temperatures are
expected to return to the low 60s to low 70s by the middle of next
week, which falls within the 75-90th percentile of normal for
mid-December. Although ERCs are currently only in the 50-65th
percentile range, a gradual uptick in fuel readiness is anticipated
amid the dry/warm conditions. The upper-level flow regime aloft will
favor the development of lee cyclones across the northern Plains
followed by cold frontal passages during the D5/Tuesday to
D7/Thursday period. Each of these cyclones/frontal passages may
support sufficient winds for elevated to critical fire weather
concerns from eastern NM into CO and southeast WY.
A few deterministic solutions hint that the best potential for
elevated/critical winds may come on D6/Wed as a strong low develops
over the northern High Plains. However, the overall synoptic regime
favors lower-amplitude upper waves that have inherent lower
predictability at this range - as evidenced by poor agreement among
GEFS/ECENS members. Similarly, run-to-run variation remains somewhat
high among long-range deterministic solutions over the past 24-48.
While the potential for fire concerns is noted due to an
increasingly receptive fuel landscape, risk highlights are withheld
until a more clear consensus among solutions emerges.
