.SHORT TERM...
(Tonight through Wednesday night)
Issued at 1247 PM CDT Tue Oct 6 2026

Dry air is keeping the weather quiescent. This morning, the dry air
and clear skies helped temperatures at Austin/Camp Mabry dip below
70F for the first time since June, and at San Antonio for the first
time since late May. This air may be at its driest Wednesday (based
on precipitable water), but the overall airmass will stick around
for the rest of the week. The dryness and clear skies will also help
temperatures warm appreciably during the daytime, but the continued
presence of northerly to easterly low-level flow should keep highs
within a few degrees of average. Highs will range from the mid 80s
to low 90s today and Wednesday. Lows will range from the 60s for
most areas with cooler conditions in the mid to upper 50s in spots
in the Hill Country.

.LONG TERM...
(Thursday through next Tuesday)
Issued at 1247 PM CDT Tue Oct 6 2026

The weather stays consistent during the latter half of the week,
with slight moderation of overnight temperatures as moisture levels
stabilize. Afternoon highs continue to stay in the mid 80s to low
90s with overnight lows in the 60s through the weekend.

An upper-level trough is forecast to amplify as it moves across the
area Thursday through Saturday. The trajectory of the trough is not
especially favorable to rain chances with its track keeping our
region under more confluent flow aloft. Areas along the Rio Grande
have about a 20% chance of showers late Thursday to early Friday as
the passing trough interacts with some westward advection of low-
level moisture. Otherwise, models have trended more towards the base
of the trough sliding south of our area, with the rest of South-
Central Texas remaining under more stable conditions. Depending on
the track of the tropical disturbance in the western Gulf, there may
be a few isolated coastal showers in the Coastal Plains Friday into
the weekend. Models have come into more of an agreement in keeping
that system well to our east, so the impacts to our area will be
minor to negligible.

Once the passing trough clears the area, ridging will rebuild over
Texas ahead of a deep trough over the Pacific coast. After a long
and somewhat uncommon streak of north winds, this will cause the low-
level flow to revert back to a more conventional southerly wind,
leading an increase in dew points and moisture early next week. This
supports broader rain chances, with the medium-range guidance
suggesting likelihood increasing towards mid-October.

.AVIATION...
(18Z TAFS)
Issued at 1247 PM CDT Tue Oct 6 2026

VFR flight conditions continue under mostly to completely clear
skies. Light north to northeasterly breezes between 5 to 10 kts
continue for the I-35 sites (KAUS, KSAT, and KSSF) during the
daytime hours before subsiding slightly after sunset. Closer to
locations near the Rio Grande, wind speeds are even lighter at
around 5 kts with variable flow through the period.
