.SHORT TERM...
(This afternoon through Sunday)
Issued at 1129 AM CDT Sat Sep 12 2026

As ridging amplifies over the South and Southeast CONUS, high
heights building in across the region will result in clear skies
and dry conditions for the vast majority of those across North
and Central Texas. Temperatures will remain at near record warm
levels for this time of year with triple digit highs expected this
weekend for much of the region.

Despite strong diurnal mixing during the afternoon and evening
hours, deep Gulf moisture will remain in place especially along
and east of the I-35 corridor with dew points struggling to drop
below the upper-60s/lower-70s. This combined with temperatures
ranging from 95-103 will result in afternoon heat indices in the
100-108 degree range today. As such, a Heat Advisory has been
issued for much of the area today through 8 PM. There may need to
be another Heat Advisory for areas along and east of the I-35
corridor tomorrow, but uncertainties in the degree of diurnal
mixing precludes an issuance decision at this time. Regardless,
heat indices Sunday afternoon and evening will be very hot, likely
ranging from 100-104 with isolated pockets (primarily north of
I-20 and east of I-35) of 105-106 degree heat indices possible.

Given the amount of boundary layer moisture in place and strong
diurnal heating expected, a stray shower or thunderstorm can`t be
ruled out (10-15% chance) across portions of Central Texas and for
areas North of I-20 and east of I-35. However, strong synoptic
scale subsidence and the lack of any surface boundaries in the
area may very well prevent the development of any convection
across the region this weekend.

.LONG TERM...
(Sunday night through next Friday)
Issued at 1129 AM CDT Sat Sep 12 2026

Strong upper-level ridging and surface high pressure are expected
to dominate the region`s weather pattern this upcoming work week.
Expect dry conditions and near-record highs (95-103 degrees) each
day.

Just beyond the current forecast period, some medium-range
guidance suggests a cold front may make it as far south as Texas
sometime next weekend. We will continue to monitor this signal and
discuss it more in future forecasts should subsequent model runs
continue to resolve this scenario.

.AVIATION...
(18Z TAFS)
Issued at 1129 AM CDT Sat Sep 12 2026

There is a low chance (10-20%) for periodic MVFR CIGS at KACT
11Z-15Z. However, confidence is too low to include in TAFs at this
time. Otherwise, VFR conditions and southerly flow (150-200) at
7-13 knots will prevail at all TAF sites for the duration of this
forecast period.
