Corpus Christi, Texas – Scattered thunderstorms could drop locally heavy rain across South Texas Sunday afternoon, with flash flooding possible in low-lying areas and urban roads. But once storms clear, oppressive heat will tighten its grip on the region through at least Thursday.
According to the National Weather Service in Corpus Christi, rainfall chances range from 10–30% Sunday, with a few storms producing downpours strong enough to trigger isolated flooding, especially near Alice, Freer, and inland Nueces County. The rain risk tapers to just 10% by Monday as a ridge builds over the area.
Temperatures will steadily climb this week, peaking between 102°F and 104°F Tuesday through Thursday across much of the Coastal Bend. Corpus Christi, Beeville, and Victoria could see heat index values well over 110°F during the afternoon hours. Winds will remain light out of the east, offering little relief.
Residents are urged to limit outdoor activities during peak heat, stay hydrated, and check on vulnerable neighbors and pets. Drivers should avoid water-covered roads and be alert to sudden downpours Sunday.
This marks one of the hottest stretches of the summer so far for South Texas. Heat Advisories may be issued if conditions persist.
