.DISCUSSION...
Issued at 1211 AM CDT Tue Jun 23 2026

Hot weather and low rain chances will persist as strengthening
mid level ridging continues to hold sway from south TX across the
northern Gulf. This pattern will continue to deflect a series
upper disturbances and associated convection north and northeast
of our area over the next several days. High temps will remain in
the lower to middle 90s (32-36 C) with heat indices topping out
in 103-107 F (39-42 C) range. Over the next few days, it`s
possible a few areas to briefly reach heat advisory criteria
during the afternoon, but with somewhat better daytime mixing,
dewpoints should drop enough to keep heat indices in check. Still,
caution is advised especially for those most vulnerable to heat
stress impacts. And for beachgoers, strong rip currents will
remain a concern over the next few days.

There are some hints the mid/upper ridge will break down enough
toward the end of the week for isolated diurnal convection to return
to southeast TX by this weekend or early next week. However,
probabilities are not yet high enough to warrant mention in the
official forecast.
