January 11, 2020 - A strong cold front with several impulses moving
northeast along the boundary moved eastward and across the region on
the afternoon and evening hours. A squall line developed just ahead
of the front and downed numerous trees across the Midlands and
Central Savannah River Area. One of the storms spawned a brief, but
strong, EF-2 tornado in Kershaw County. The tornado seriously
damaged a high school.


Here is the damage survey assessment of the tornado.

...Summary... Considerable damage occurred to North-Central High
School in Kershaw County as a result of an EF-2 tornado with maximum
wind speeds of 130 mph. The tornado began near the intersection of
Lockhart Rd and Keys Ln, then traveled northeast across the campus
of North-Central High School before lifting approximately a half
mile later beyond the parking lot on the northeast side of the
school. The tornado snapped numerous pine trees at the beginning of
the track, then partially collapsed concrete stadium bleachers and a
press box. The tornado continued across the gymnasium, lifting all
of the HVAC units off the roof. The tornado then lifted most of the
roof off of the main office and an older auditorium, then collapsed
the exterior wall along a portion of the west side of the building.
The tornado then moved into the parking lot on the north side of the
building where it moved 4 school busses, and resulted in broken
windows and other damages to 25-30 parked school busses. The tornado
then destroyed a small building just beyond the parking lot before
lifting. Strong inflow into the tornado also snapped numerous pine
trees south of the baseball field, collapsed 2 large light stands
near the baseball field, and lifted and displaced a conex shipping
container approximately 50 yards. The tornado path length was about
0.50 miles and the path width was about 150 yards.
