Back in 2011 the Super Outbreak had started. The night before four people had been killed when a wedge tornado struck Vilonia in Arkansas. SPC had issued a High Risk for April 26, driven by a 30% chance for (significant) tornadoes in the corners of Oklahoma, Texas and Arkansas. The day did bring many tornadoes, with the storm system continuing into the night. Overnight it turned into a line with strong wind gusts and tornadoes killing several people in Mississippi and causing widespread power outages.
