.SHORT TERM...
(Monday through Wednesday)
Issued at 1033 PM CDT Sun Jun 29 2025

Tropical Depression Barry has made landfall in Eastern Mexico, 273
miles south of Brownsville. Its remnants are bringing showers and
some thunder to the region tonight, and an increased swell is
leaving a Moderate Risk of rip currents. These showers and coastal
hazards are the only anticipated impacts to Deep South Texas from
TD Barry. While flash flooding is not anticipated, PWAT values of
2.25" from the 00Z sounding indicate plenty of moisture available
and may allow for heavy rain rates, which can lead to ponding.

Showers are likely (70-80%) with thunderstorms possible today as
moisture influx from Barry`s remnants work northward. The chance
for showers and thunderstorms will continue through Wednesday,
with rain chances beginning to decrease Monday night. Rain chances
are moderate (50-60%) on Tuesday with thunderstorms possible, and
low (10-20%) Wednesday. High moisture content lead to heavy
rainfall within showers possible.

High temperatures early this week start off below normal - highs
in the 80s will not feel realized with this increase of moisture,
leaving apparent temps in the 90s to around 100 by midweek.
Seasonable low temperatures in the 70s provide little relief.

At the local beaches, increased swell from TD Barry maintains a
Moderate Risk of rip currents.

pressure builds over the central US. A Moderate Heat Risk is

triple digits.
