.KEY MESSAGES...
- A Heat Advisory is in effect for all of North and Central Texas
today.
- The overall fire threat will be lower today due to increased
cloud cover and lower wind speeds. However, continue to take
caution to avoid sparking wildfires. Smoke from ongoing
wildfires will continue to reduce visibility in some areas.
- Low (10-30%) storm chances today, bringing the potential for
gusty winds.

.SHORT TERM...
(This evening through Thursday)
Issued at 1214 PM CDT Wed Aug 26 2026
Widespread mid level cloudiness has persisted across the western
half of North Texas, in association with a weak remnant MCV which
originated in the Panhandle last night. Where thickest, these
clouds have retarded the diurnal temperature somewhat, though
virtually all locations should still attain the century mark
today. At the surface, a weak front has pushed eastward into the
I-35 corridor, bringing winds around to a west to northwest
direction across our western counties. The boundary will slow its
progression this afternoon, but overtake most of North Texas by
sunset before stalling. The mid clouds will continue to spill
eastward across I-35 during the afternoon, while eroding gradually
due to afternoon heating/mixing. Scattered showers accompanying
this MCV during the morning have largely fizzled out as of midday.
That said, a low end chance of additional convective development
will exist across most of the area, owing to residual lift from
the MCV, and modest instability.
Later tonight, short-term models are promoting a slightly better
chance of shower and isolated thunderstorm development across our
Central Texas zones. Chance PoPs were introduced across most of
this region, with lesser chances farther north into the DFW area.
Thursday will bear some similarities to today, while likely
featuring a bit more sunshine. A weak surface low will evolve
over Southeast Texas, creating a north to eventually northeast
low level windflow across North and Central Texas from late
morning through the afternoon. With the center of the persistent
upper level ridge drifting westward this week, daytime high
temperatures will be tempered slightly, with afternoon readings
topping out in the upper 90s to lower 100s areawide.
Heat indices will top out in the 105-110 range across the bulk of
the area this afternoon, necessitating a continuation of the Heat
Advisory for most of the area. An advisory was extended through
tomorrow afternoon, though its western extent was trimmed back
slightly due to the presence of drier air across Western North
Texas.
Smoke from the wildfires across Western North Texas will continue
to affect many areas west of I-35 through at least Thursday.
Visibilities in a few spots, mainly in the closest proximity to
the Ross Fire, will be reduced today and tonight, but should not
intensify enough to warrant any Dense Smoke Advisories.
Nevertheless, this will remain a noticeable factor across these
areas over the next 2 days at least.

.LONG TERM...
(Thursday night through next Tuesday)
Issued at 1214 PM CDT Wed Aug 26 2026
The semi-permanent upper high which has afflicted most of the
southern U.S. all month long will continue to drift westward
through the remainder of the week, helping to take a little edge
off of the hot temperatures across North Texas. Day to day highs
will remain a few degrees cooler than the readings endured a few
days ago. Unfortunately, the high center will reverse course and
move back over OK/TX by the weekend. The increased subsidence
associated with this center will promote a return of daily highs
in the lower 100s over most of North Texas from the weekend on
through mid week. Farther south, slightly weaker subsidence
coupled with higher moisture will result in daily highs in the
upper 90s. With normal highs now running in the mid 90s, these
ongoing afternoon readings will remain anywhere from 3 to 8
degrees above normal through most of next week. As of now, no
appreciable forcing mechanisms are appearing in the extended
guidance, and thus rainfall chances will remain nearly zero.

.AVIATION...
(00Z TAFS)
Issued at 638 PM CDT Wed Aug 26 2026
An isolated thunderstorm continues to weaken and move through
D10 at the start of this TAF period. Outflow winds gusting 25-40
knots will remain possible before 01Z in addition to lightning in
the vicinity of D10 terminals. After this storm dissipates, there
will continue to be a very low chance (10-15%) for a stray shower
or thunderstorm throughout the overnight, but probabilities are
too low warrant inclusion in the TAFs at this time. Near KACT, a
cold front will stall in proximity to the terminal resulting in
variable wind directions and several potential flow changes
before reinforcing north winds arrive by 16Z tomorrow morning.
