Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1021 AM CST Mon Dec 15 2025
Valid 151700Z - 161200Z
...NO CRITICAL AREAS...
Fire weather potential remains limited for today. Dry conditions are
noted across portions of the Southeast where RH values are falling
into the low 30s. While dry conditions will continue, a combination
of weak winds and recent rainfall should mitigate more substantial
fire concerns. Elsewhere, localized elevated conditions appear
likely within the immediate lee of the Laramie Mountains in
southeast WY, but as with yesterday, these conditions are expected
to remain sufficiently localized to preclude highlights. See the
previous discussion for additional details.

.PREV DISCUSSION... /ISSUED 1126 PM CST Sun Dec 14 2025/
...Synopsis...
Cold air will continue to move into the Southeast today. Some dry
and breezy return flow is possible in the southern Plains, but cool
temperatures/higher RH will also be present. The most likely
location for localized fire weather concerns will be east of the
terrain in southeastern Wyoming. There, downslope warming and breezy
conditions supported by a weak lee trough and modest mid-level flow
will promote potentially elevated conditions. However, the
duration/intensity of those conditions is too much in doubt for
highlights.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1132 PM CST Sun Dec 14 2025
Valid 161200Z - 171200Z
...NO CRITICAL AREAS...
...Synopsis...
Some modest breakdown of the upper ridge across the CONUS can be
expected on Tuesday. A weak front will move out of the High Plains.
There will be some increase in mid-level winds across the Rockies as
well. Where sufficient downslope warming occurs within the
central/southern High Plains, fire weather could approach elevated
criteria locally. Confidence in location/duration are too limited
for highlights.

U.S. Day 3-8 Fire Weather Outlook

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0248 PM CST Sun Dec 14 2025
Valid 161200Z - 221200Z
Confidence in the potential for critical fire weather conditions
remains limited for the country through the extended period.
Long-range guidance and cluster analyses continue to trend towards a
more active upper-level flow regime heading into the upcoming work
week. This pattern shift will favor surface cyclone development
across Plains/Midwest with most guidance showing a reasonably strong
signal for intense cyclone development across the northern
Plains/Great Lakes during the D4/Wed to D5/Thur period. A similar
signal for cyclone development is noted heading into the upcoming
weekend (albeit with considerably higher model/ensemble
variability). In general, this synoptic regime will promote
rain/snow chances from the Pacific Northwest and northern Rockies
into the Midwest and southeastern states with predominantly dry and
warm conditions expected for the Southwest and southern Plains.
...D5/Thursday - D7/Saturday - Central/Southern High Plains...
A return to warm and dry conditions is anticipated for the work week
with temperatures expected to climb into the mid/upper 60s for
portions of the southern High Plains by mid-week. These temperatures
will reside near the 90th percentile of seasonal normal for the
region, and will promote steady dead/dormant fuel drying through
late week. The development of a series of strong surface lows and
cold frontal passages beginning D4/Wed and lasting through the
weekend may support strong enough winds for periods of elevated to
critical fire weather conditions across portions of the central and
southern High Plains each afternoon. While most deterministic and
ensemble solutions generally agree in the overall pattern,
considerable variability persist among guidance. This limits
confidence in which day/regions will see the greatest fire weather
threat, though risk probabilities may eventually be needed as model
consensus improves in the coming days.
