What the reports say
Written by National Weather Service staff at the time of the event · public domain
County comms reported that the second severe thunderstorm produced larger than baseball size hail on the west side of the city. Multiple car windshields were reportedly broken out and skylights were broken at a department store.
A massive severe thunderstorm moved south from the Shelby, NC, area into northern Cherokee County and moved slowly across the county. This was a major hail storm with golf ball- to baseball-size hail falling for more than an hour. The largest hail, and the most damage, seemed to occur in the area from south of Gaffney to Jonesville. Up to five inches of rain fell causing localized urban flooding – though none was reported to reach flash flooding levels. Some trees were blown down although the main impact was hail and rain.
