Scattered showers and thunderstorms are developing this evening across the Ohio Valley. With marginal amounts of instability and plenty of wind shear, isolated severe weather will be possible. The main threats from any storms will be damaging wind and large hail. Heavy rain and lightning will also be likely this evening as the showers and storms become more widespread overnight.
Showers will come to an end early Wednesday morning giving way to some sunshine once again. A few scattered showers may develop during the peak heating of the day in the afternoon hours. Expect highs to reach the lower 70s with temperatures cooling off in the evening.
A large upper level area of low pressure will move through the Midwest and Great Lakes for the remainder of the week. This will bring cooler weather and scattered showers to Columbus for Thursday through Saturday. As of right now, the weather is looking better on Sunday for graduation at Ohio State! Expect temperatures in the middle 60s under partly cloudy skies.
