For four days in mid April, severe thunderstorms spawned deadly tornadoes across the Central United States.
The outbreak occurred over a wide area, stretching into the Great Lakes region.
There were six fatalities, all were in the community of Woodward, Oklahoma where a powerful tornado tore through a mobile home park on April 14th.
It was confirmed as an EF3 tornado on the Enhanced Fujita Scale, packing winds between 219 and 266 km/h.
The twister destroyed 10 homes, and damaged nearly 90 others.
The following day, the Oklahoma state government declared a state of emergency in 12 counties. Soon after a federal disaster declaration request was filed.
That opened the door to federal aid so temporary housing and low-interest loans could be provided.
Oklahoma wasn't the only state hit hard by the outbreak. On April 15th, a state of emergency was declared in Kansas, where tornadoes, large hail and flooding caused widespread damage.
The outbreak earned its place in the history books.
It was only the second time on record, that a high risk of severe weather was issued by the U.S. Storm Prediction Center on two consecutive days. The first was on April 7th, 2006, when powerful thunderstorms spawned about 70 tornadoes across more than a dozen southern states.
Thirteen people died in that outbreak, most were in Tennessee.
