Summary of the Event

The year is 2020, it started very slow with tornadoes on an all-time low. The total tornado average by April 2nd was near 12 tornadoes. On April 3rd, the Storm Prediction Center issued a high risk for Ohio extending west into Indiana. Along with the issuance of the high risk, there was a 30% hatched tornado threat, 30% hatched wind threat, and a insane 60% hatched hail threat in Ohio. Many people were shocked and thought of it as a joke. Many news outlets would commonly speak of the April 27th, 2011 outbreak as a reference. Many power lines were down from a early morning mesoscale convective system. The downed power lines caused loss of communication throughout rural areas and some urban areas. This would cause the loss of life to double more than expected. A staggering 31 deaths would be counted up and over 500 people would be injured. A total of 3 EF0s, 2 EF1s, 5 EF2s, 7 EF3s, 1 EF4, and 3 EF5s. would touchdown during the event.

The enhanced risk would include, a 5% tornado threat, 30% hatched wind threat, and a 5% hail threat. The enhanced risk was issued for the early day mesoscale convective system that brought swaths of destruction throughout Indiana, Ohio, Pennsylvania, and West Virginia. Most damage was done from the fierce winds of the system. Many power lines would be brought down and many homes would receive 80+ mph straight line winds that would cause roof damage. Some trailer homes were flipped on their sides due to the fierce winds. As the mesoscale convective system leaves the swath of destruction, many people wouldn't realize it was a crucial setup for the evening storms. A tornado warning would be issued for the city of Columbus, Ohio at 6:41AM. The tornado warning would soon be dropped at 7AM. There was no confirmed tornado damage however the radar indicated rotation would be considered as 115MPH straight line winds. The time would be 8AM by the time the early morning storm would leave the Ohio region and push into Pennsylvania and weaken rapidly. By 12PM, a high risk was issued from the Storm Prediction Center. The high risk would be in Indiana, Ohio, and extreme west parts of West Virginia and Pennsylvania. It would consider of a 30% hatched tornado threat, 30% hatched wind threat, and a incredibly high 60% hatched hail threat.
