What happened

The episode as NWS SHV wrote it up.

A stationary front across northern Oklahoma and the Arkansas/Missouri border began moving southward during the overnight hours of March 25th and the predawn hours of March 26th. This front encountered some surface instability but moderate elevated instability across Southeast Oklahoma and portions of Southwest Arkansas. Deep Layer Shear values across this region was in excess of 35kts in association with a weak shortwave that was moving into this region as well. Lapse Rates were in the order of 7-8 degrees C/KM. Once storms developed across the region...they produced small hail.
