Issued at 1022 PM CDT Thu Sep 11 2025
An unsettled weather pattern continues across Deep South Texas as
ample moisture and weak impulses moving over the region will
continue to bring rain chances to Deep South Texas and the RGV,
especially in the afternoon. Rain chances will remain 20-50%
through Saturday, with a slight decrease in POPs on Sunday
(20-40%). A weak coastal trough begins to set up late this weekend
and will linger through next week with rain chances Monday
through Friday of 30-60%. The highest chance of rainfall will
coincide with the heating of the day and the sea breeze.
Temperatures will remain near normal each day with heat indices of
100 to 105 degrees through Saturday, then falling to upper 90s to
around 100 degrees for the remainder of the forecast period. Heat
Risk will be generally Minor (level 1 out of 4) with pockets of
Moderate (level 2 out of 4), mainly across the lower and mid
Valley, for the forecast period.
A moderate risk of rip currents is expected at area beaches over the
next few days.
