.SHORT TERM...
(Tonight through Friday night)
Issued at 124 PM CDT Thu Jul 30 2026

Heat will continue to be the main concern across South Central
Texas as the region remains under the influence of mid/upper level
ridging, although the ridge is expected to shift west towards the
Desert Southwest tomorrow. Stratus clouds will once again develop
late tonight, which should limit overnight cooling and result in
another warm and humid night with lows in the mid to upper 70s. A
few areas that remain mostly clear may observe temperatures in the
low 70s, most likely across portions of the Hill Country. Morning
stratus should scatter/lift by mid to late morning on Friday,
making way for another hot afternoon across the region. Highs will
remain near to slightly above normal for late July standards, with
most areas warming into the upper 90s to 100 degrees, and a few
areas across the Rio Grande Plains warming to around 100-103
degrees Friday. Slightly lower afternoon dew points should keep
heat index values below Heat Advisory criteria. However, it will
still be hot and anyone spending time outdoors should continue to
take proper heat safety precautions to avoid heat-related
illnesses.

.LONG TERM...
(Saturday through next Thursday)
Issued at 124 PM CDT Thu Jul 30 2026

The ridge remains centered over the Desert Southwest this weekend,
placing South Central Texas beneath northwesterly flow aloft.
Meanwhile, an upper level trough translating across the Plains is
expected to send a weak frontal boundary southward on Saturday and
Sunday. Ahead of this boundary, precipitable water values are
expected to increase, but guidance continues to range from around
1.5 inches to near 2 inches. Isolated to scattered showers and
storms may develop as early as Saturday morning across portions of
the Hill Country, but most likely Saturday afternoon, as the
frontal boundary pushes south, and Saturday night into Sunday
across the Coastal Plains. A few strong storms cannot be ruled
out, primarily with a gusty wind or small hail threat. Otherwise,
rainfall amounts are forecast to remain fairly light as the front
moves through the region.The first week of August will feature
seasonably hot temperatures and rain-free conditions as the
influence of the ridge returns once again. Triple-digit heat index
values are likely along and east of the I-35 corridor, so
continue to practice heat safety!

(00Z TAFS)
Issued at 604 PM CDT Thu Jul 30 2026

VFR flight conditions begin the period with few mid-level daytime
cumulus and few to sct passing high clouds. Late overnight into
early Friday morning, an area of low stratus develops across the
central portions of the region along the Balcones Escarpment,
resulting in a period of MVFR ceilings at KSAT and KSSF. It could
briefly result in MVFR conditions at KAUS as well while KDRT and
areas along the Rio Grande remain primarily VFR. All sites then
return to VFR levels by mid-morning and remain VFR through the
rest of the period with few mid-level cumulus and high cloud
cover. Moderate south-southeasterly breezes continue this
evening, especially after sunset for KSAT and KSSF, before speeds
subside after midnight into early Friday morning. The south-
southeasterly breezes then pick back up from mid-morning through
the afternoon Friday.
