.DISCUSSION...
Issued at 1032 PM CDT Wed Jul 9 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. At the surface, high pressure holds across
the Gulf, maintaining southeasterly flow across Deep South Texas
through the forecast period. Rain chances generally remain very
low (below 15 percent) through the rest of the week, potentially
limited by a large plume of Saharan dust through Friday. Above
normal moisture returns over the weekend, nudging rain chances
slightly to near 20 percent, still mainly isolated along the sea
breeze Saturday into Monday.

Drier air and potentially another round of Saharan dust arrives
by mid next week, dropping rain chances once again. Expect near
normal temperatures into early next week with humidity boosting
the Heat Risk from minor (level 1 of 4) Thursday to mostly
moderate (level 2 of 4) Friday through Tuesday. Above normal
temperatures arrive by Wednesday and Thursday, with drier
conditions, maintaining generally minor to briefly moderate Heat
Risk. 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 feet will bring back a
moderate risk of rip currents by Friday afternoon to the lower
Texas coastal beaches.

northern nearshore waters due to gusty winds. There remains a low
