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.
