Powerful storms killed at least 15 people and left a wide trail of destruction Sunday across Texas, Oklahoma and Arkansas after obliterating homes and destroying a truck stop where dozens sought shelter in a restroom during the latest deadly weather to strike the central U.S. The storms inflicted their worst damage in a region spanning from north of Dallas to the northwest corner of Arkansas, and the system threatened to bring more violent weather to other parts of the Midwest later in the day and to the East Coast on Monday. Seven deaths were reported in Cooke County, Texas, near the Oklahoma border, where a tornado Saturday night plowed through a rural area near a mobile home park, officials said. Storms also killed two people and destroyed houses in Oklahoma, where the injured included guests at an outdoor wedding. Tens of thousands of residents were without power across the region.
