Mainly during the afternoon hours on Wednesday, March 15th, showers and thunderstorms developed across Middle Tennessee again in a broad area of increased instability and moisture centered across the southeast U.S aided also by outflow from a mesoscale convective system that moved across southern Kentucky during this time period. With another day of unseasonably warm surface temperatures, but significantly colder air just off the surface and aloft, severe thunderstorms that developed across the mid state produced large hail in several counties. Hail reports ranged from penny to golf ball size. Thunderstorm wind damage and flash flooding also occurred.
