.NEAR TERM...
(Rest of tonight through Saturday night)
Issued at 1158 PM CST Fri Nov 14 2025

Late Friday evening, despite a weak southerly flow (most areas) there
was a notable demarcation in dewpoint temperatures across western
Oklahoma and western north Texas. Low-level winds will increase
and become more veered during the overnight hours into Saturday
morning, as a pre-frontal trough and cold front approach. This
will keep the near-surface moisture very shallow even across
eastern parts of Oklahoma. As heating and mixing occurs early
Saturday morning, drier air will push eastward. Meanwhile, 60
degree dewpoint temperatures will advect northward into north
central Oklahoma which may result in a patchy dense fog through
through mid morning Saturday.

But the main weather story for Saturday will be another day of
record heat.  A cold front will move across at least the northern
2/3rds of Oklahoma by late afternoon, but very weak cold advection
will be associated with the boundary.  Temperatures reached the lower
90s across western north Texas Friday afternoon and similar readings
are expected this afternoon.  It`s certainly possible Wichita Falls
will reach 90 degrees which will be the latest 90 degree reading in
November. However, in December of 2021 (the 24th) 90 degree weather
was recorded, so it would not be the latest in the calendar year.

Wichita Falls   85
Lawton          85

The fire weather environment will become elevated Saturday afternoon
as well, especially across southwestern Oklahoma and western north
Texas, where little if any cool advection will reach this region
before peak heating. Much of western Oklahoma will also see
afternoon humidity at or slightly below 20 percent, but overall
wind speeds will be a mitigating factor for fire weather. We will
issue a Fire Danger Statement for parts of western Oklahoma and
western north Texas.

The cold front/wind shift will reach most areas by Saturday night
with the exception being parts of southeastern Oklahoma.  The air
behind the front will not be overly dry, but dry enough for low
temperatures to fall into the 40s and lower 50s (most areas).

.SHORT TERM...
(Sunday through Monday night)
Issued at 1158 PM CST Fri Nov 14 2025

Record temperatures are not expected on Sunday, but well above
average temperatures will prevail with northeast to east surface
winds.

Late Sunday into Monday, a shortwave trough will move across the
central Plains.  As an associated surface low moves across Kansas
Monday, breezy southwest winds, near record heat, and low humidity
will elevate fire weather conditions.  Afternoon humidity Monday is
expected to reach 20-25 percent across western Oklahoma and western
north Texas. Earlier forecast suggested better cooling would
occur as this system lifted to the northeast, but this may only
occur across the northern half of Oklahoma (albeit weak).

&&

.LONG TERM...
(Tuesday through next Friday)
Issued at 1158 PM CST Fri Nov 14 2025

After the Monday system moves northeast of the southern Plains,
richer Gulf moisture should be displaced just to our south in
northern Texas and perhaps along the Red River Valley of Oklahoma.
As a full-latitude trough moves across the West Coast, a warm front
may begin to lift northward into southern/central Oklahoma late
Tuesday into Wednesday.  This may result in at least scattered
showers and thunderstorms with better chances across the southern
half of Oklahoma and northern Texas.

This is expected to be the general setup, but some ensemble
members suggest a slower movement of the trough which may delay
the onset of much needed precipitation. Currently, the quickly
solution is favored which will bring the bulk of the precipitation
from very late Tuesday into Thursday of next week. Locally heavy
rainfall is possible during this period too.

.AVIATION...
(18Z TAFS)
Issued at 1105 AM CST Sat Nov 15 2025

VFR ceilings expected this TAF period, except for KDUA where MVFR
ceilings could move into the area early Sunday. SW winds will
shift towards the N and NW this afternoon/evening as a cool front
continues to move across the area.
