Ohio Supercell Time-Lapse
It was already after 7:30 p.m. by the time that a pair of supercells were approaching I-70, to the southeast of Columbus, Ohio. With daylight dwindling and not much else lighting up on radar, I setup along an on-ramp to watch the storm approach in New Concord.
The storm (the northern cell) as a whole had broad rotation, but even though some rotation was showing up on radar, this storm was more visual than it was actually severe.
In this clip, the storm can be seen approaching from the west-southwest. The time-lapse makes the broad rotation more apparent and both a flanking line and shelf can be seen.
