Several rounds of severe thunderstorms are forecasted for parts of South Carolina on Wednesday and Thursday, as a mid-level disturbance slowly makes its way eastward from the Central Plains. The main area at risk Wednesday is the northern Midlands and Upstate. On Thursday, strong storms are possible over the entire state.
Forecasters at the Storm Prediction Center have classified parts of the Upstate including Greenville and Spartanburg under a slight risk for severe thunderstorms on Wednesday. That is a level 2 out of 5 in terms of risk. The latest forecast guidance suggests that scattered severe thunderstorms could develop across parts of northern South Carolina at lunch time with another round of storms developing in the evening hours. Some strong storms could persist through the overnight hours and into most of Thursday. All severe hazards, including some isolated tornadoes, damaging hail, and severe or damaging winds could occur.
The slight risk for severe weather will likely spread across all of South Carolina on Thursday. Storms will be pushing mainly west to east throughout the next 24-36 hours. These storms are expected to be more linear, with a threat for linear tornadoes also possible. Hail and damaging wind gusts will be possible with thunderstorm activity through Wednesday night with the threat increasing most of Thursday. Storms will likely begin to impact the forecast area as early as 2-5 AM on Thursday, with the storms pushing east through the morning hours towards the coast by early-mid afternoon.
