.DISCUSSION...
Issued at 1026 PM CDT Thu Jul 10 2025

Weak mid-level low pressure remains sandwiched along the lower
Texas coast with high pressure across the Desert SW and eastern
Gulf into this weekend. Current Saharan dust plume is expected to
dissipate into the weekend. At the surface, high pressure holds
across the Gulf, with low pressure across northern Mexico,
maintaining moderate to gusty southeasterly flow across Deep South
Texas, especially Friday and Saturday. Rain chances generally
remain low, currently around 15 percent Friday and Saturday along
the sea breeze, then below 10 percent Sunday and Monday. Drier air
and another round of dust arrives next week, keeping rain chances
below 10 percent.

Expect seasonal temperatures gradually warming next week with
humidity boosting the heat risk to moderate (level 2 of 4) across
Deep South Texas into late next week. Skies may be hazy through
Friday and again next week, with periods of degraded air quality
for sensitive groups.

Increasing swell periods and surf around 3 to 4 feet will
maintain a moderate risk of rip currents late Friday through
Wednesday across the lower Texas coastal beaches.
