Low pressure moving through the Great Lakes and a trailing cold front will collide with very moist air to trigger occasional showers and storms, with the heaviest activity later in the afternoon and early evening across central Ohio. A few storms will likely be strong to severe, with powerful gusts.
The cold front will gradually push southeast overnight, with lingering showers ending early Friday. Drier and cooler air with high pressure building down from the Great Lakes will bring some partial sunshine in the afternoon and lower humidity, as temperatures stay in the pleasant 70s.
Another storm system in the central Plains will draw warm, humid air back into Ohio over the weekend, as the front lifts north as a warm front, with several round of showers and a few storms. High temperatures will top out in the 70s Saturday and low 80s Sunday.
Warm and humid conditions with scattered mainly afternoon storms will prevail early next week, with low pressure weakening over the mid-Mississippi Valley.
