21 March 2015 Tornado Outbreak

This twiser outbreak was the ultimate 'reasonable' tornadic day of all time. Hundreds of twisters scoured multiple states, especially Texas, which had over 300+ tornados alone, and overall, this one day alone featured at least 13 EF4 tornados along with [coincidentally] five EF5 twisters. More than 450 people were killed at the end of the day. As of 13 August 2016, it was finally confirmed that the final death toll was 464, and more than $4.9 billion in damages were done.

Tornado Totals
At least 517 twisters were reported, as 414 were confirmed. This twister outbreak hit a few metropolitan areas, and even had multiple villages entirely flattened.

Fatality by State
More than 330 fatalities were claimed in Texas, 174 from just one tornado in that state.

[You guys can edit this later, but make it reasonable! Example: Instead of 36 EF5s and 75 EF4s with over 400,000 fatalities, make it the same as before, which were 461 fatalities, 13 EF4s and 5 EF5s.] And only include the ones that did damage.
