Severe thunderstorms developed during the afternoon hours to the east of a surface low pressure system located over southwestern Oklahoma and near a stationary frontal boundary that was draped across northeastern Oklahoma and northwestern Arkansas. Several of these storms developed supercell characteristics due to a very unstable air mass that was in place over the region coupled with strong vertical wind shear. These supercells produced a couple tornadoes, hail up to baseball size, and wind gusts to around 85 mph.
The storms evolved into a line during the evening hours and moved swiftly across northwestern and west central Arkansas, producing wind damage and hail to golfball size.
Locally heavy rainfall as a result of the storms moving repeatedly across the same locations produced localized flash flooding. A flash flood fatality occurred in Carroll County when a vehicle was driven into flood waters and was swept off the road.
