Broad high pressure over the region brought a couple of very warm days with comfortable humidity, and highs topping out in the low 90s in Columbus.
A southerly shift in the wind will allow the humidity to slowly increase through the day, resulting in more cloudiness and isolated storms in northern Ohio ahead of a weak cold front. Temperatures will peak in the mid- to upper 80s, readings overnight will only fall into the 70s. A few showers and storms will enter northwest Ohio late tonight and move southeast into central Ohio toward daybreak.
A cold front will push south Thursday across Ohio, triggering scattered rain and storms, with some threat of severe weather later in the day during peak heating. A few storms could produce damaging wind gusts, cells will contain heavy rain and sharp lightning across the southeastern half of the state.
Behind the front, much cooler and less humid weather will bring a nice weekend. A weak front could clip Ohio Sunday with a few spotty showers and strengthen the pleasant northwesterly flow heading into the first week of August.
