A band of heavy rain and thunder caused localized ponding on a few roads early this morning after locally 1 to 3 inches of rain fell overnight across parts of central and southern Ohio, accompanied by rumbles of thunder.
A flash flood watch has been issued for southern Ohio until 8 p.m., where very heavy rain fell south of U.S. 50 down to the Ohio River, leaving the soil saturated, with up to another inch expected.
A steamy end to June also provided some needed rain. We have one more day of very muggy weather, but without the extreme heat, as clouds and showers hold temperatures to the 70s.
Weak disturbances in a warm, moist southwesterly flow have triggered clusters of showers and storms. A frontal boundary will slowly sink south through the day across Ohio, representing the leading edge of cooler, drier air.
Showers and a few storms will redevelop this afternoon with heating and linger early tonight before gradually ending, before the front pushes south of the Ohio River and low pressure moves through the Mid-Atlantic states.
A pleasant change tomorrow will reflect northerly winds, with a mix of clouds and sun and a few instability showers over the eastern portion of the state. High pressure will arrive from the Upper Midwest and bring more hours of sunshine and a comfortable pattern over the holiday weekend. An upper-level ripple could trigger a few late day showers and storms Sunday.
Very warm air and moderate humidity will return beginning Monday, with scattered storms possible Tuesday and Wednesday.
