A volatile weather system is poised to unleash severe thunderstorms across the central United States on Sunday, with the potential for tornadoes, large hail and damaging winds. Nearly 175 million people from Illinois to eastern Texas and beyond could be affected, as unseasonably warm air collides with a powerful cold front.

The Dallas-Fort Worth area could see scattered strong to severe storms move through the region early Wednesday morning through the afternoon. The National Weather Service said storms would most likely develop after 3 a.
