The ongoing heatwave poses significant risks to residents across Texas, particularly in areas where heat index values exceed 110°F (43.3°C). Prolonged exposure to such high temperatures can lead to heat-related illnesses, especially for vulnerable populations such as the elderly, children, and those with pre-existing health conditions. The Rio Grande region is expected to face the most severe heat, with temperatures potentially reaching 112°F (44.4°C). While the cold front will bring some relief, it will primarily make conditions 'less hot' rather than cool, according to the NWS.
