Scattered showers from a crossing upper-level disturbance will diminish through the rest of this morning. Lingering cloud cover will initially limit destabilisation but midday warming and abundant moisture will eventually lead to the development of thunderstorms as a cold front approaches later in the day.
12:45PM UPDATE | The Storm Prediction Center has downgraded the threat for severe storms to a marginal risk (1/5) in all areas of Ohio except for a small area in northeast Ohio with their noon update. A Marginal Risk means that isolated strong to severe thunderstorms will be possible.
All severe modes will be in play this afternoon and evening. The biggest threat will come from damaging wind gusts of 58 mph or better in the strongest storms. There is a lesser threat for large hail. Tornadoes are not much of a concern.
Abundant moisture at the surface and drier air aloft will limit thunderstorm coverage. But, it will also allow the potential for some storms to lift fairly high and pull down upper-level winds. While just about all areas will get into some thunderstorms this afternoon and evening, severe storms will likely be scattered across east-central Ohio.
High resolution guidance suggests the best odds for scattered strong storms will be mid-afternoon into early this evening. The threat for showers and storms will exit the area as the front travels south of the area.
