The extreme heat poses significant risks, particularly for vulnerable populations such as the elderly, children, and those with pre-existing health conditions. Heat indices of up to 105°F (40.5°C) can lead to heat-related illnesses, including heat exhaustion and heatstroke. The potential for severe thunderstorms on Sunday could bring damaging winds and hail, adding to the weekend's weather hazards. Residents in the affected areas, especially in the Twin Cities and southern Minnesota, should remain vigilant and take necessary precautions.
