A powerful storm is expected to move through the Central U.S. Saturday, sending a squall line of destructive storms through the Mid-South and dumping heavy snow on the Upper Midwest. The system is likely to weaken considerably before reaching South Carolina, but it still might be capable of producing a few severe thunderstorms upon its arrival late Saturday night.
A few showers or thunderstorms might develop across portions of the Palmetto State as early as the afternoon hours Saturday, but it likely won’t be until after sunset that the strongest storms first arrive in the Upstate region. The line of cells with potential wind gusts to 60 mph would then move toward the Midlands overnight, and then slow down and continue weakening in the Lowcountry Sunday morning.
A significant episode of severe weather is not expected with this system, and the thunderstorms are not likely to be widespread. However, there will likely be several hours of rain that falls in the western half of South Carolina Sunday, and gusty winds are expected ahead of the front statewide on Saturday and Sunday.
