...NO CRITICAL AREAS...
...Synopsis...
Fire weather concerns are expected to remain low today across the
CONUS. Much of the central US and Plains states will be under the
influence of post frontal cool continental air mass. Surface high
pressure across the central US will begin to shift eastward as a
trough departs the northeast. Some lingering dry/breezy conditions
will be possible across the Texas Permian basin. Marginal relative
humidity and lack of receptive fuels will keep fire spread concerns
low.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1045 PM CST Sun Dec 07 2025
Valid 091200Z - 101200Z
...NO CRITICAL AREAS...
...Synopsis...
Surface troughing across the Plains will bring dry and breezy
conditions to portions of western Texas on D2/Tuesday. Recent days
of dry and breezy conditions across western Texas from the Caprock
south to the Permian Basin have allowed fuels to dry steadily.
Forecast ERCs indicate fuels will be around the 50th-60th percentile
across some portions of these regions on Tuesday. Afternoon relative
humidity reductions to 15-20 percent may briefly overlap winds
around 10-15 mph for localized Elevated fire weather concerns.
Overall, it doesn't appear that this overlap of drying fuels and
elevated meteorological conditions will be widespread enough for
inclusion of any areas.

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0317 PM CST Sun Dec 07 2025
Valid 091200Z - 151200Z
...Synopsis...
Medium range ensemble guidance suggests a somewhat stagnant
upper-level long wave pattern persisting across CONUS through
midweek. The eastern U.S. will remain entrenched in a broader trough
while ridging slowly amplifies and intrudes farther into the western
states through the weekend. The broader northwesterly flow regime
over the central U.S. should provide a source for colder,
continental air mass intrusions into the eastern U.S., particularly
over the weekend time frame which will limit fire weather concerns.
Farther west under the slowly amplifying ridge, dry conditions
should encompass much of the Southwestern U.S. while above normal
temperatures expand west of the Continental Divide. Despite the
upcoming persistent dry conditions across the Southwest, a diffuse
surface pressure gradient and thus lower wind speeds along with
marginal fuel dryness should allay broader fire weather concerns.
...Day 3/Tuesday - Southern High Plains...
A surface trough extending southward from a deepening surface low
across the Northern Plains should promote some overlap of lower
relative humidity and breezy west/southwest winds across
southeastern NM and West Texas on Day 3/Tuesday. However, marginal
fuel dryness precludes introducing critical probabilities at this
time.
