Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1254 AM CST Thu Feb 12 2026
Valid 121200Z - 131200Z
...NO CRITICAL AREAS...
...Synopsis...
Upper ridging will prevail over the Plains as a mid-level trough
approaches from the west, and another upper trough progresses
further over the Atlantic today. Surface high pressure will dominate
over the Mississippi Valley to the East Coast, with moist return
flow expected over the southern Plains given potential weak surface
low development. Overall, quiescent fire weather conditions are
expected CONUS wide. However, a dry low-level airmass will
overspread portions of the Southeast and the central High Plains,
supporting drying fuels and perhaps localized wildfire growth
potential.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1255 AM CST Thu Feb 12 2026
Valid 131200Z - 141200Z
...NO CRITICAL AREAS...
...Synopsis...
Upper ridging will traverse the Southeast as a mid-level trough
overspreads the Southern Plains tomorrow (Friday). Surface high
pressure and associated cooler temperatures will linger over the
Appalachians and points east. Meanwhile, surface low development
over the southern Plains will promote a continued moistening
low-level airmass, along with appreciable rainfall accumulations
from showers and thunderstorms. As such, quiescent fire weather
conditions are expected across the CONUS on Friday.

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0351 PM CST Wed Feb 11 2026
Valid 131200Z - 191200Z
Very active upper and mid-level flow will persist across CONUS
through the extended forecast period. An upper trough and associated
surface low will move from the southern High Plains early Day
4/Saturday eastward across the Deep South/Southeast states through
Day 5/Sunday. Another upper-level trough enters the West on Day
6/Monday, progressing east over the Central and Southern High
Plains. Elevated to locally Critical fire weather is expected this
weekend and possibly early next week, given the strong mid-level
flow and increasing western US troughing.
...Texas Big Bend and Rio Grande Valley: Day 4/Saturday...
Dry and breezy conditions are expected to develop Day 4/Saturday
afternoon/evening as the mid/upper-level trough impinges on the area
and an associated surface low strengthens over the Southern Plains.
Uncertainties remain regarding precipitation placement on Day
1/Wednesday and also Day 4/Saturday. Ensemble guidance continues to
suggest a relative minimum in precipitation across portions of South
Texas into the Rio Grande Valley. The aforementioned area could see
RH values between 15-25 percent and west-northwesterly surface winds
of 15-25 mph. A 40% probability of Critical fire weather conditions
will be maintained where the dry and breezy conditions will likely
overlap dry fuels.
...Southern and Central High Plains: Day 5/Sunday - Day 6/Monday...
Fire weather conditions may increase across portions of the Southern
and Central High Plains on Day 5/Sunday and Day 6/Monday as a
mid-level trough approaches from the west and a surface lee cyclone
strengthens. Increasing southerly flow and low relative humidity
could support increasing fire weather potential given dry fuels.
There is some uncertainty given the potential for precipitation this
weekend, precluding the introduction of probabilities currently.
Later in the week (Day 7/Tuesday - Day 8/Wednesday) the secondary
mid-level trough will move from the west across the Rockies into the
Central and Southern High Plains region. Varying model trends and
significant timing differences lend to lower predictability
regarding the evolution of this system. However, the potential
exists for a strong lee-cyclone and downslope flow supporting
Critical fire weather conditions later in the week. Nonetheless,
this is conditional upon fuel moisture given the possibility of
rainfall earlier in the forecast period.
