.DISCUSSION...
Issued at 1210 PM CDT Fri Jul 18 2025

A generally hot and rain-free period for Deep South Texas and the
Rio Grande Valley. Upper-level high pressure will continue to be the
biggest influence for the weather over the region allowing for more
subsidence to occur and thus limiting chances for rain. While a
stray shower or thunderstorm with the seabreeze cannot be ruled out
for the period, the chances for rain are very low (less than 10%).

Mostly sunny skies are expected for the period allowing for
temperatures to rise as well. The high temperatures are expected to
generally range from the mid 90s to the lower triple digits.
However, the heat indices at this time are generally expected to
only range from 105-109. There are a few days that are an exception
to this. Both Monday and Wednesday show a several locations in
Kenedy county approaching 110. While that is below the criteria for
Heat Advisory. It is still a good idea to practice heat safety and
limit time outside especially during peak heating hours. Another
notable exception is that on Tuesday, the heat indices in Kenedy
county do exceed 111 for a short period of time. While not long
enough for warrant a Heat Advisory, a Special Weather Statement for
heat could be issued. The heat risk for the period is mostly
Moderate (level 2 of 4). The low temperatures for the period are
mostly in the 70s, with a few places on the extreme southern
portions of the CWA approaching 80.

With swell and surf expected to remain low for the next couple of
days, the risk of rip currents along the Lower Texas coast is
expected to remain low.

.MARINE...
Issued at 1210 PM CDT Fri Jul 18 2025

Generally favorable conditions are expected with light to moderate
southeasterly winds and slight to moderate seas. High pressure over
the Lower Texas coast will keep rain chances to a minimum through
the period. A slight increase in the southeasterly winds over the
Laguna Madre and Nearshore Gulf waters that result in Small Craft
Exercise Caution for short periods of time starting this weekend and
continuing through the middle of next week as winds are forecasted
to be around 15 knots.
