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 The National Weather Service conducted a storm survey in Union County Arkansas and concluded that storm damage was the result of an EF1 tornado. The tornado touched down at around 10:12 AM, in the town of Norphlet. An old gas station cover was blown down and several trees were snapped along Black street eastward across Hayes St. Some minor roof damage occurred to homes along Hayes street. The tornado continued eastward crossing N Tate Road where a carport collapsed on a vehicle and several trees were snapped or uprooted. The tornado continued along the south side of Tate Road snapping trees and peeling shingles from several homes. The tornado lifted east of a pasture where several hardwood and softwood trees were snapped or uprooted. A small metal outbuilding suffered structural damage as well. Maximum winds are estimated at 90-100 mph.
