Powerful storms spawned deadly tornadoes across southern Michigan and eastern Oklahoma on Friday, killing eight people and injuring at least two dozen others. The National Weather Service confirmed multiple touchdowns, including an EF-3 tornado with winds exceeding 150 mph in Michigan's Branch, Cass, and St. Joseph counties.

In Michigan, three people died and 12 were injured near Union Lake, west of Union City in Branch County, where the tornado flattened homes in a lakeside neighborhood and scattered debris across the area. Three of the injured were hospitalized, according to Branch County Sheriff Frederick Blankenship, who warned of power outages, closed roads, and disrupted cellular service. About 50 miles southwest, a 12-year-old boy named Silas Anderson was killed in Cass County near Edwardsburg, with several others injured. Damage extended to Three Rivers in St. Joseph County, where roofs were torn from buildings, trees uprooted, and power lines snapped. Search and rescue operations continued Saturday morning as crews cleared debris and assessed a damage path stretching from Edwardsburg through Three Rivers to Union Lake.

Oklahoma saw four fatalities linked to the storms. On Thursday night, a 47-year-old woman and her 13-year-old daughter died when an EF-2 tornado struck their vehicle near Fairview in Major County. The mother had been on the phone, urging her other children to seek shelter when contact was lost. Friday's storms killed a married couple in a house destroyed near Beggs in Okmulgee County, about 30 miles south of Tulsa; two others were hospitalized. The tornado carved a four-mile path, demolishing four homes, wrecking vehicles and tractors, killing a horse, and damaging a middle school and bus barn. Okmulgee County Emergency Manager Jeffrey Moore called it a "tragic, significant event."

Governor Kevin Stitt declared a state of emergency Saturday for affected counties and urged residents to report damage and assist neighbors. In Tulsa, storms damaged the Tulsa Tech Peoria Campus with debris and fallen trees, though no one was inside. Over 15,000 homes statewide lost power, and flash flooding prompted water rescues in Wagoner County.

The two-day outbreak produced at least 13 tornado reports from Texas to the Great Lakes, fueled by a supercell thunderstorm system bringing damaging winds, large hail, and heavy rain. Michigan's state emergency operations center was activated, and National Weather Service teams began surveys on Saturday. Additional severe thunderstorms were possible Saturday from Texas to New York, with flash flooding risks lingering.
