Episode Narrative A strong upper level short wave move from west to east across the Central Plains states of the U.S. driving a cold front southeast into the Four State Region. Strong to severe thunderstorms formed in the unstable air mass ahead of the cold front. The front and at least 3 lines of thunderstorms moved through the Four State Region from west to east during the day. Strong low level shear in the atmosphere allowed some thunderstorms to rotate, producing tornadoes with damaging straight line winds producing downbursts.
Event Narrative This tornado was a continuation of the tornado that first touched down in extreme northeastern Grant Parish. Numerous trees were uprooted/snapped, with some falling on homes as the tornado tore through the Zenoria community before it lifted just northeast of Highway 84 about 5 miles southeast of Tullos. Numerous trees along the path were snapped/uprooted. Falling trees blocked Highway 84. Several homes were damaged when trees fell on/through them. One car was crushed from a falling tree in the Zenoria community. One house directly affected from the tornado in Zenoria had some shingles removed from the roof, with a tin roof of a shop behind the home having been peeled off and thrown forward into some nearby trees.
