The most recent information is pointing toward the strongest storms across the Southern half of Ohio. These locations will have warmer and more humid air to help sustain stronger storms. Northern Ohio will stay cooler and while strong storms/showers with gusty winds are possible, not as likely to be as strong.
The main threat with the storms will be strong gusty winds and very heavy rain. The forecast model below is a projected radar image for midnight Thursday night. I think the timing is looking more like 9PM to 1AM for the leading edge of the storm to roll through Columbus. It will be a very quick moving storm and push to the east rapidly.
So a few showers early Thursday then the strong line of storms later in the evening. More updates tomorrow. Have a good one!
