This tornado was on the western edge of an outbreak of storms which has been nicknamed the "Super Tuesday Outbreak" because it occurred on a huge presidential primary night.
Gassville was hit by an EF2 tornado at about 5:10 that evening.
Another powerful EF4 tornado tore a record path through Arkansas, striking Mtn. View and Ash Flat among other locations.
I have a write-up on this storm here.
