Extreme Heat Wave in South Texas

Extreme heat is surging in South Texas, potentially breaking a national temperature record of 108 degrees in March. The heat is unusual for this time of year and is expected to affect vulnerable groups like the elderly, young people, and pets. The hot weather is part of a larger weather pattern causing warm air to pool over central states. The heat is traced back to the tropical central Pacific Ocean, leading to compressional warming and hot, dry conditions in South Texas.
