The heat dome poses significant risks to vulnerable populations, including children, the elderly, and individuals with pre-existing medical conditions. Prolonged exposure to these conditions increases the likelihood of heat-related illnesses such as heat stroke. High humidity levels will amplify discomfort, and the lack of cooling overnight will prevent recovery from daytime heat stress. Communities across Texas and the Gulf Coast are expected to experience the most severe conditions by midweek. While the Mid-Atlantic, Northeast, and Pacific Northwest are likely to avoid the extreme heat, the central U.S. will endure oppressive weather conditions.
