Severe storms will be possible across the upstate in the Midlands on Tuesday night into Wednesday morning. A wide, low-pressure system moving through the Plains pushes a warm front from the south across the Southeast. Behind this warm front is a cold front, and the risk for severe storms exists in between.
The biggest threats from these severe storms are damaging winds of at least 60 mph, large hail, and a few tornadoes moving through early Wednesday morning, some of which could affect the Midlands. By the afternoon, some storms will be moving through the Pee Dee and Lowcountry, but the risk will be of isolated severe storms.

Another low-pressure system and a cold front will approach the region to end the week. The low will stay well to our north but bring a push of cold air. As the cold front approaches the area from the west, the chance for showers and thunderstorms will increase again on Thursday. By Monday, a low-pressure system and a cold front will move from the south, bringing warm south winds, and the temperatures will respond and rise.
South Carolina will continue with above-average temperatures through Wednesday, while Thursday will be closer to average temperatures. There will be a noticeable drop in temperatures to end the week. But the Palmetto State will stay divided, with the western part experiencing below-average temperatures through the weekend and into early next week. In contrast, the eastern half will stay with slightly above-average temperatures.
