Fast-moving hailstorms rumbled through the Ohio Valley, bringing with them a mix of awe and concern for residents across Illinois, Indiana, Kentucky, and Tennessee. Reports poured in of large hail, with some stones reaching up to 2.5 inches in diameter around Bellair, Illinois, painting a stark picture of the storm's intensity. These hailstorms, fueled by a persistent warm front, are expected to continue their march across the region, posing a significant threat through Wednesday morning.
