A Heat Advisory is in effect for the Rio Grande Valley (Starr, Hidalgo, Cameron, Willacy) and Kenedy County, except for the barrier island, for afternoon heat index values generally between 110 and 114F. People outdoors should hydrate continuously and take frequent breaks; all should seek cooler locations.
After the rains Monday and Tuesday, heat returns in a big way, beginning Wednesday and peaking Thursday and Friday. "Feels-like" temperatures will surge to 111 or higher Wednesday afternoon and 120 or higher for many Thursday afternoon, the highest since mid/late June, 2023. Overnight conditions are not much better, with feels-like temperatures remaining in the 90s Thursday and Friday night. Check on elderly and vulnerable populations to ensure they have access to cool locations, especially overnight.
With the hottest "feels-like" temperatures in three years (since mid-June 2023) on their way to the Valley, it's critical to follow these heat-safety tips beginning Wednesday and continuing through at least Friday. Most importantly, find cool locations by day and especially at night.
After a cloudy and stormy Monday and especially Tuesday, hazy sunshine returns to the beaches today. With oppressive heat returning inland, the beach will be inviting...but be aware of moderate south-to-north longshore currents, embedded rip currents, and difficult swimming conditions.
Here are the forecast low temperatures and rain chances for Deep South Texas tonight.
Here are the forecast high temperatures and rain chances for Deep South Texas tomorrow.
Dangerous "feels-like" temperatures peak on Thursday (Extreme Heat) and may continue into Friday before easing back a few degrees to more typical late-June levels as the summer solstice arrives on Sunday. Isolated to perhaps scattered late Saturday afternoon and evening thunderstorms may reach the Rio Grande Plains and Brush Country.
