Greenville, South Carolina – A powerful line of thunderstorms is expected to sweep through Upstate South Carolina on Friday, bringing the threat of damaging winds, hail, and intense lightning between 10 a.m. and 3 p.m.
According to the National Weather Service in Greenville-Spartanburg, the cold front will move east across the region late Friday morning, triggering strong-to-severe storms across the area. The most likely arrival time is between 10 a.m. and noon in the mountains and noon to 3 p.m. in the Piedmont, including Greenville, Spartanburg, and Gaffney.
Cities east of the mountains, including Rock Hill and Chester, could see the strongest impacts. The storms may disrupt travel on I-85 and US-29 during the midday commute. Residents should secure outdoor items, charge devices ahead of time, and remain weather-aware as conditions can change quickly.
This weather system marks one of the stronger convective events of late May, with all severe hazards on the table — including isolated tornadoes. School dismissal times and afternoon activities could be affected depending on storm timing.
Severe weather warnings remain possible throughout the day Friday. Be sure to have multiple reliable ways to receive alerts, including mobile apps, NOAA weather radios, and text notifications.
