Instability in the upper levels of the atmosphere produced the cold air funnels, he said.
The National Weather Service confirmed a couple of very brief narrow tornado touchdowns Saturday evening in northern Miami County and southern Shelby County.
The tornadoes did not produce any damage, according to both the Miami County Sheriff’s office and the Ohio State Highway Patrol’s Piqua Post.
There were reports of funnel clouds seen in Clark and Champaign counties. Sirens also went off in Champaign County, but no warning was issued there.
A warning in Shelby and Miami counties expired just before 9 p.m. The type of funnel cloud people saw is typically short-lived and very rarely touches down, according to the weather service.
“These are not tear the house off the foundation tornadoes,” said WHIO-TV Channel 7 Meteorologist Jamie Simpson.
