What happened
The episode as NWS SHV wrote it up.
A cold front pushed through the Four State Region during the evening hours of April 27th. Supercell type thunderstorms developed along the frontal boundary with some hail noted with the storms. The pre-frontal atmosphere was moderately unstable but cold air aloft was sufficient enough for vigorous updrafts to form and therefore the development of hail. One of these supercell thunderstorms spawned a tornado in Bienville Parish that uprooted and snapped several trees in an unpopulated area of the parish.
