As a powerful trough ejected into the Central Plains on March 18, the Storm Prediction Center issued a Slight risk for Severe Weather stretching from southern Nebraska to western Texas.
That evening, many supercells evolved across the Texas Panhandle and Oklahoma, producing large hail and damaging wind gusts.
As the supercells moved towards the northeast, four tornadoes were produced across western Oklahoma, all rated an EF0 on the Enhanced Fujita Scale.
The following day, the Storm Prediction Center issued a Moderate risk of Severe Weather, encompassing much of central and eastern Texas, into southeastern Oklahoma and extreme western Arkansas.
[citation needed] A slight risk was issued for parts of the Ohio Valley, but notable tornado activity was not expected.
