As millions across the Midwest and Northeast continue to battle the Canadian wildfire smoke, AccuWeather meteorologists are monitoring the risk of severe thunderstorms that could bring some relief from the smoke.

Somewhat cooler and less humid air will expand from the Great Lakes to northern portions of the mid-Atlantic and clash with very warm and humid air across the Southeast, setting the stage for severe thunderstorms from western South Carolina to eastern Virginia on Sunday.

Storms in this zone can produce flash flooding and damaging wind gusts up to 65 mph. The AccuWeather Local Storm&trade is 75 mph.

On Monday, severe thunderstorms will focus farther west and become more widespread across the Midwest as a cold front from central Canada moves into the region. From central Iowa to much of Michigan and northern Indiana, storms will be capable of producing hail, damaging wind gusts, tornadoes and flooding downpours.
