.DISCUSSION...
Issued at 145 PM CDT Fri Jul 24 2026

Deep South Texas will remain under the influence of ridging aloft
through most of next week, which will maintain the summertime
heat and generally rain-free conditions. High temperatures will be
fairly close to seasonal normals to start the weekend, but a
gradual uptick in temperatures is expected throughout the week
with highs around 3-6 degrees above normal for late July. Expect
widespread afternoon high temperatures in the triple-digits across
most of Deep South Texas next week, with the exception being
along the immediate coast and along the lower Texas beaches. Some
areas across the region may approach daily record highs and
highest lows as well. Persistent low level southerly to
southeasterly flow will maintain elevated humidity across the
region, and the combination of high humidity and above normal
temperatures will result in heat index values ranging from 100-115
degrees each afternoon. Heat products are likely for portions or
most of the region next week.

The combination of near-record temperatures and elevated humidity
will result in a moderate (level 2 of 4) to major (level 3 of 4)
Heat Risk next week. Warm overnight low temperatures will not
allow for much recovery from the daytime heat and can result in an
increased risk of heat-related illnesses. Continue to practice
heat safety  wear sunscreen, light-colored loose-fitting
clothing, take frequent breaks in the shade or indoors, and stay
hydrated!
