What happened

The episode as NWS OHX wrote it up.

During the early morning hours on Wednesday, April 27th, twelve tornadoes occurred across Middle Tennessee. Seven of these were EF0 tornadoes and five of these were EF1 tornadoes. Numerous thunderstorm wind damage events, along with several flash flooding events, occurred across the mid state also. This severe weather outbreak was the result of a very unstable airmass across Middle Tennessee ahead of a strong frontal system, with a warm front positioned near the Tennessee/Alabama border. As this frontal system pushed across the area through the remainder of the morning through the early evening hours, several thunderstorm wind and flash flood events also occurred as additional severe thunderstorms developed.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Nashville, TN wrote its last area forecast discussion before the first event at Apr 25, 10:40 PM CST, 1 hour 48 minutes earlier.
