Anniversary of April 3-4, 1974, Tornado Outbreak

This was the the biggest known outbreak of violent tornadoes in recorded history (there is evidence there was an even worse outbreak in the 19th Century).

There are two articles about the outbreak that are well worth your time.

• How the outbreak would have, due to urban sprawl, hit many cities that were missed in 1974. 
• The outbreak and TV meteorology is here. 
• A personal memoir from Alabama is here. 

If you are interest in tornadoes, this is very interesting reading.
