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 Columbia County Arkansas and concluded that storm damage was the result of an EF1 tornado. The tornado touched down at around 9:28 AM, south of Waldo AR along county road 153 ripping off tin from a small barn. A home east of CR 153 sustained minor roof damage and the adjacent garage sustained minor roof damage and some structural damage. The tornado continued east southeast crossing CR 148 where several trees were snapped and uprooted. A home sustained minor roof damage and a small shed had half of its roof torn off. Further east���several trees were snapped and uprooted in a field and a abandoned home had portions of its roof torn off and thrown southeast. The tornado lifted on the south side of cr 148. Maximum winds are estimated at 85-90 mph.
