Scattered high-based convection moved from the Texas Panhandle into portions of western Oklahoma during the afternoon of the 13th. Sufficient wind shear and instability combined to yield a mix of semi-organized cells and clusters across the region, resulting in a few reports of large hail with initial activity. By the evening, convection organized into a mesoscale convective system (MCS) and moved across portions of north-central Oklahoma. Multiple severe wind gusts were reported as this line swept through the aforementioned areas.
