Residents across North Texas should prepare for extreme heat conditions, with heat index values ranging from 100°F to 115°F (37.8°C to 46.1°C) later this week. Prolonged exposure to high temperatures can lead to heat-related illnesses, particularly for vulnerable populations such as children, the elderly, and those with pre-existing health conditions. Outdoor workers and individuals engaging in physical activities outdoors are at heightened risk. Heat alerts may be issued as temperatures rise further.
