As an upper low, and accompanying developing surface low,  traversed the region during the morning to early afternoon hours, a few storms produced small hail and strong gusty winds. A Mesoscale Convective Vortex (MCV) appeared to develop and produced strong wind gusts and some damage around Lake Murray and the central Midlands of SC.   Additional convection east of the MCV produced some localized wind damage.
