Overview

Multiple lines of thunderstorms formed across southeast Missouri after midnight on April 2, 2024. The southern line really took off as it quickly ejected east across the Mississippi River, racing across southern Illinois and into western Kentucky and southwest Indiana between 3 and 7 AM. This thunderstorm complex remained intact across Kentucky and all the way to West Virginia. This event officially met the definition requirements of a derecho, with widespread significant wind damage. Embedded within the line were dozens of circulations that led to 19 tornadoes across our forecast area. This was the most tornadoes in a single event across our Quad-State region since Halloween 2013 (19 tornadoes that day). There were 7 EF-2's, 11 EF-1's, and 1 EF-0 tornadoes with this event.
