The extreme heat poses significant risks, particularly to vulnerable populations such as children, the elderly, and individuals with pre-existing health conditions. Prolonged exposure to high temperatures and humidity increases the likelihood of heat-related illnesses, including heat exhaustion and heat stroke. The moist air around the heat dome is also creating volatile weather conditions, with risks of severe thunderstorms, flash flooding, and hail around the Great Lakes region. Authorities warn that the heat could persist into the week, with only temporary relief expected in the central U.S. by midweek.
