The episode as NWS PAH wrote it up.
Thunderstorms increased ahead of a cold front that extended from western Missouri to northwest Arkansas. The atmosphere remained moderately to strongly unstable through the night. Couple with at least 40 knots of deep-layer westerly shear, the storms grew into a mesoscale convective system that produced isolated wind damage.
