What happened

The episode as NWS ILM wrote it up.

Thunderstorms initiated along the Piedmont trough during the early afternoon and quickly became severe as they organized and generated a cold pool. This cold pool bowed out ahead of the main line of storms through the late afternoon and early evening. Incredible instability was present with CAPE values in excess of 6000 J/kg combined with steep lapse rates to produce widespread severe weather.

The radar

The Columbia radar (KCAE), 147 km away, was scanning. The volume nearest the first event began at 18:59 UTC.
