.DISCUSSION...
Issued at 1048 PM CDT Sun May 24 2026

Drier weather is forecast for the area Monday, with rain chances
generally remaining below 10% with mostly sunny skies. Some
showers and thunderstorms may develop over Mexico Monday
afternoon, however most guidance keeps the development south of
the area, where better instability and forcing are likely.

Rain chances are forecast to increase again Tuesday and Wednesday
as an upper level trough moves into West Texas. PWAT values are
forecast to increase above 2 inches again Tuesday and Wednesday,
which could support heavy rainfall across portions of the CWA.
Given the antecedent soil moisture from recent rainfall, some
isolated to scattered slash flooding will be possible with these
storms. The Weather Prediction Center has a Marginal Risk of
Excessive Rainfall for the northwestern half of the CWA Tuesday
and the eastern half of the CWA Wednesday. Some of these
thunderstorms storms may be strong to severe Tuesday as they
approach Deep South Texas, and the Storm Prediction Center has
Zapata County under a Marginal Risk for Severe Weather.

Drier conditions look to return again Thursday and Friday, though
some isolated showers or thunderstorms along the sea breeze cant
be ruled out Thursday afternoon.
