.DISCUSSION...
Issued at 135 PM CDT Sat Jul 25 2026

Heat will be the main weather concern across Deep South Texas
through next week as the region remains under the influence of
ridging aloft. The rest of the weekend will feature temperatures
close to seasonal normals for late July, with highs ranging from
the mid to upper 90s to around 102 degrees. A warming trend begins
heading into the work week, with triple-digit high temperatures
expected across most of the region, with the exception being along
the immediate coast and lower Texas beaches. This is around 3-6
degrees above normal for late July, and a few areas may tie or
break daily record high temperatures and highest low temperatures
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 Advisories are likely each afternoon next week, with a few
areas potentially reaching Extreme Heat Warning by mid week.

The combination of near-record temperatures and high 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!
