The wildfire smoke has posed significant health risks, particularly for vulnerable populations such as children, the elderly, and those with respiratory conditions. While air quality is expected to improve in many areas, some regions, including parts of the Upper Midwest and western Great Lakes, may see a return of smoke early next week due to shifting winds. Severe storms accompanying the cold front could also bring risks such as strong winds and potential tornadoes, particularly along the I-95 corridor in the Northeast and Mid-Atlantic.
