.SHORT TERM...
(Today through Tuesday)
Issued at 1259 AM CDT Mon Jun 22 2026

Low clouds have begun to develop across the Coastal Plains and
spreading across portions of the I-35 corridor, Hill Country, and
southern Edwards Plateau. This trend continues overnight through
Monday morning. Also, can`t rule out a few pockets of low visibility
across portions of the Hill Country and southern Edwards Plateau
during the middle overnight period and sunrise. In addition to the
low level clouds moving from south to north over most of the local
area, there is a cluster of storms forecast to push across northeast
into central Texas overnight into Monday morning. This boundary is
likely sending a low level cloud deck over the Hill Country into the
San Antonio area before dissipating mid Monday morning. Then a good
mixing is forecast with low clouds breaking and dissipating giving
way to partly cloudy to mostly sunny skies. High temperatures are
forecast to reach the low to mid 90s across most of the local area
and mid to upper 90s along the Rio Grande Plains and southern
Edwards Plateau. With a good mixing scenario in place, heat index
values are likely to range from 100 to 107 from noon to 9 PM Monday
evening. Can`t rule out a few spots getting to 108 and 110 for a few
hours along the I-35 corridor and Coastal Plains and 110 to 113 for
parts of the Rio Grande. With that said, we are holding off on a
Heat Advisory. A Special Weather Statement could be issued during
the daytime to address any concern about heat index values once
clouds break and temperature/dewpoint combo evaluated. Otherwise, a
dry and warm day is in store for Monday with a nice southerly breeze
and gusts of 20 to 25 mph in the afternoon and early evening.

Low clouds return Monday evening and continue through Tuesday
morning. Overnight lows stay in the 70s areawide. By Tuesday
afternoon, we are expecting mostly sunny to sunny skies across South
Central Texas with highs in the low to mid 90s across most areas and
mid to upper 90s along the Rio Grande.

.LONG TERM...
(Tuesday night through Sunday)
Issued at 1259 AM CDT Mon Jun 22 2026

Dry and warm weather conditions are forecast across South Central
Texas through the work week into next weekend. An upper level ridge
between the southwest states and northern Mexico is forecast to
dominate and block disturbances from the north to reach the local
area through the long term forecast period. Highs stay in the 90s
and lows in the 70s.

.AVIATION...
(06Z TAFS)
Issued at 1259 AM CDT Mon Jun 22 2026

Overcast MVFR CIGs are near continuous over SAT/SSF, with a more
BKN profile of clouds over AUS. This should fill in nicely over
the next hour, and some BKN CIGs should begin to impact DRT as
early as 07Z. We show BKN CIGs at DRT a few hours later as the
Rio Grande Plains clouds are more erratic and sparse in some
areas as seen in the Nighttime Microphysics imagery. The trends
were somewhat typical this morning in terms of the mixing to VFR,
so we`ll continue that trend into later this morning. No IFR cigs
are in the TAFs but there could be a brief lowering at any of the
TAF sites near daybreak. More low clouds are expected to arrive
near or shortly after midnight at AUS/SAT. No convection is
expected in the region today.
