Residents in the southern half of the Jackson, Mississippi area should prepare for severe thunderstorms capable of producing damaging wind gusts during the late afternoon and evening hours. The extreme heat poses a significant health risk, particularly in southwest areas where heat index values may reach 115°F (46°C). Vulnerable populations, such as the elderly, children, and those with pre-existing health conditions, are at heightened risk of heat-related illnesses. Air quality concerns may exacerbate respiratory issues for sensitive groups.
