Corpus Christi, Texas –South Texas faces a one-two punch of intense heat and rising thunderstorm chances today, with highs soaring into the upper 90s and lower 100s from Corpus Christi to Beeville. Dangerous heat index values and the risk of strong afternoon storms could disrupt travel and outdoor plans through Saturday night.
According to the National Weather Service in Corpus Christi, thunderstorms are likely to increase this afternoon, especially east of I-37, where highs are forecast to reach 99°F in Cotulla, 102°F in Corpus Christi, and up to 104°F in Victoria and Rockport. The risk for dangerous rip currents remains low on area beaches, but swimmers are urged to stay vigilant near piers and jetties.
Major roadways—including US-77, TX-44, and coastal access routes—may see brief flooding or delays as heavy rainfall pushes through. Local power outages are possible where storms hit hardest, especially in eastern counties like Refugio, San Patricio, and Aransas. Area beaches report moderate UV levels, water temps in the upper 80s, and low risk for rip currents, but lifeguards advise beachgoers not to swim alone and to avoid strong currents. Residents are urged to stay off the roads during downpours, charge devices, and prepare for sudden wind gusts. This system brings some relief from relentless heat, with Saturday highs ranging 90-99°F and overnight lows in the upper 70s.
The first major rain event of July comes after weeks of near-record heat, recalling last summer’s drought-busting storms. Despite a brief cooldown Sunday, expect a warming trend early next week with highs rebounding into the low 100s and rain chances tapering off.
The threat for storms will diminish after Saturday, but heat advisories could return as temperatures climb next week. Stay tuned for updated alerts, and be prepared for sudden changes in weather through Wednesday.
