After 'Fast Start' to Severe Weather Season, What Should Ohioans Expect for 2024?

Ohio has had an unusually high number of tornadoes over the past three months.

This includes a tornado in Clark County that tore through over 90 homes. In Logan County, a recent tornado took lives with it.

Over the past 30 years, Ohio has averaged around 21 tornadoes a year. This year, there have already been 18 confirmed.

Fast start to severe weather season

Brandon Pelonquin, a warning coordination meteorologist with the National Weather Service in Wilmington, said the tornado count most likely won’t stop there.

“The main idea here is we've already got off to a fast start with the severe weather season,” Pelonquin said. “Looking at some of the patterns and projections, that active weather pattern that could support severe weather looks to continue as we go into April.”

The weather pattern Pelonquin is referring to is a combination of different weather systems in the atmosphere interacting with each other.

Jana Houser, Ohio State University professor and atmospheric scientist, said low pressure systems and irregular temperatures create favorable conditions for tornadoes to form.

“But what really differentiates rotating storms and tornado potential is not just having these unstable conditions present, which is a requirement, but you also need to have a situation where your winds change in both speed and direction as you're going up through the atmosphere,” said Houser.

More tornado potential

Houser said in the winter, Ohio doesn't usually have warm enough conditions that are needed to create atmospheric instability, which is responsible for storm weather.

That could be why, historically, tornadoes in Ohio occur most frequently during May, June, and July.

But this February was the second warmest on record in Ohio. Tornadoes need both cold air and warm moist air in order to form, according to Houser.

She said it’s hard to connect this trend to climate change.

But she also said “there might be a a shift in seasonality, where we start seeing some of those more robust events happen earlier in the calendar year.”
