The Tornado East Texas Never Saw Coming was the name of a tornado that hit the small East Texas town of Lovelady, Texas on April 18, 2014. There was no tornado watches or warnings at all. As it turned out, Lovelady happens to be in the middle of a "blind spot", meaning that there was no radar close enough to detect anything within 12,000 feet in the air.
