South Carolina – Rain is already soaking parts of the Upstate, and another round of thunderstorms is expected to develop through the day. Wet pavement, reduced visibility and localized flooding could quickly affect the afternoon commute before warmer, drier weather returns later this week.
According to the National Weather Service in Greenville-Spartanburg, showers and thunderstorms remain likely through today with an 80% chance of rain and a high near 77 degrees. Most locations can expect one-quarter to one-half inch of rainfall, while stronger thunderstorms could produce locally higher totals in a short period.
Drivers along Interstate 85, Interstate 26, U.S. 221 and U.S. 29 should prepare for changing road conditions as heavier rain moves through. Standing water may develop in low-lying areas, and visibility could drop rapidly during downpours. Slow down, leave extra following distance and never drive through flooded roadways.
The broader weather pattern across the Southeast continues to support repeated rounds of showers and thunderstorms. Abundant moisture and slow-moving storms increase the risk for isolated flash flooding where heavier cells repeatedly track over the same locations. A few stronger storms could also produce gusty winds, frequent lightning and small hail. While tornado potential remains low across the Upstate, meteorologists continue monitoring storm development as conditions evolve.
Rain chances stay elevated into Tuesday before a gradual improvement begins Wednesday. Sunshine becomes more common by Thursday, allowing temperatures to climb sharply into the lower 90s. After several cooler, damp days, the return of summer heat will be noticeable across the region.
If you’re heading outdoors, keep a weather app nearby and be ready to move inside when thunder is heard. Travelers should allow extra time and expect slower traffic during heavier rain.
