More than 90M Americans under risk of thunderstorms, hail and possible tornadoes this weekend

Strong weekend storms are expected to bring a variety of impacts to the East Coast, including thunderstorms, hail, gusty wind and possibly even a few tornadoes, causing a sense of relief from the recent heat and smoky conditions.Warm and muggy temperatures are once again plaguing portions of the East Coast, but thick Canadian wildfire smoke could throw a wrench into exactly how hot it gets.Fortunately, this warm, smoky pattern will break as storms move in this weekend.The heat dome parked across the East Coast will still keep temperatures hot and humidity levels high through Friday.But the massive wildfire smoke remains a wildcard for daily temperatures.The thick layer of smoke acts like a filter, scattering and reflecting incoming sunlight before it can reach and heat the ground, according to the FOX Forecast Center.As we head into the weekend, a slow-moving cold front will sweep through the East Coast.This incoming front will trigger widespread, heavy showers and thunderstorms, beginning Friday in the Ohio Valley and continuing through Sunday across portions of the Mid-Atlantic.While these storms will carry a risk of damaging winds, downpours and frequent lightning, the greatest concern will be Saturday.
