.SHORT TERM...
(Tonight through Thursday night)
Issued at 1202 PM CDT Wed Jul 29 2026

Seasonably hot temperatures, rain-free conditions, and persistent
southerly to southeasterly winds will continue through the short
term period across South Central Texas as the region remains under
the influence of mid level ridging centered over the Texas
Panhandle and New Mexico. Expect another warm and humid night
tonight with lows mostly in the mid to upper 70s as stratus clouds
develop once again across the region. Otherwise, areas that
remain partly to mostly clear should realize low temperatures in
the low 70s.

Morning stratus clouds are expected to scatter/lift by mid to late
morning on Thursday, with scattered diurnal cumulus clouds
through the afternoon hours. Another hot afternoon is in store
across South Central Texas, with temperatures around 1-3 degrees
warmer as subsidence increases. Areas along and east of the I-35
corridor may reach 100-102 degrees Thursday afternoon. Deeper
afternoon mixing should result in dew points falling mostly into
the 60s, which should keep heat index values below heat advisory
criteria, generally ranging from 95-105 degrees west of I-35 and
closer to 100-107 degrees along and east of I-35. Regardless of
any heat headlines, continue to practice heat safety if spending
time outdoors to prevent heat-related illnesses.

.LONG TERM...
(Friday through next Wednesday)
Issued at 1202 PM CDT Wed Jul 29 2026

The relentless summer heat will continue through the end of July
with triple-digit high temperatures as ridging aloft prevails.
Heat index values are expected to be higher than earlier this week
as well as humidity increases via persistent low level southerly
to southeasterly flow. Heat headlines may be needed as heat index
values approach 108-110 degrees Saturday afternoon, mainly along
and east of the I-35 corridor.

There will be a limited opportunity for isolated to scattered
showers and storms across portions of South Central Texas. The
aforementioned ridge aloft is expected to shift west over the
Desert Southwest, placing our region beneath northwesterly flow.
This will allow for a weak frontal boundary to track across South
Central Texas late this weekend. However, there are still
discrepancies on the timing of this weak boundary among
deterministic guidance on any convective development over the
weekend, and most precipitation chances are capped at 20% or less
for late Saturday afternoon and Sunday. More seasonable
temperatures return Sunday and into early next week.
