| 1 | February 28, 2011 | Greenville | (EF0) A line of showers and thunderstorms entered the mountains of the western Carolinas and northeast Georgia during the late afternoon hours. The line intensified and expanded northward as it moved out of the mountains. An environment of high shear and moderate instability supported several strong to severe storms within the line. Most the severe weather was the result of straight line winds, though there were a few reports of large hail. One QLCS tornado was spawned along a strong bowing segment over the upstate. The storms crossed the foothills and western piedmont during the early evening hours, a little ways ahead of a strong cold front. NWS survey found a short tornado path embedded within a larger area of downburst winds. The track began along Goodwin Rd, just east of Goodwin Bridge Rd. Numerous trees were snapped off or uprooted toward the northeast along the east/southeast oriented damage path that roughly paralleled Goodwin Rd. One tree fell on and damaged a mobile home. The underpinning was blown out from underneath and a metal awning tossed from another mobile home. The tornado crossed highway 25 before lifting in the Boswell Rd area just before its intersection with highway 414. | 1.53 | 50 |
| 2 | February 28, 2011 | Newberry | (EF1) Severe thunderstorms produced wind damage and spawned one tornado as they moved across the Midlands of South Carolina.
