Here is a look at satellite and radar this morning. Showers and storms are around the Chicago area this morning. Those showers and storms are associated with a cold front that will move down into our area later this evening.
The SPC (Storm Prediction Center) in Norman, OK has put areas mostly north of I-70 under a slight risk for severe weather. Everyone else is under a marginal risk for severe weather. A slight risk mean we could have a few thunderstorms reach severe limits tonight. A marginal risk means we could a few strong to possible severe storms.
Here is what our severe weather threats look like for now. There is a low chance for a spin up of a tornado, hail, and damaging winds. Flooding appears to be very low at this time even though we could see some ponding on roads tonight from steady to heavy rain.
So those showers and storms in the Chicago area this morning will fizzle out. More showers and storms will develop near Chicago and move southeastward towards Indiana and Ohio. These showers and storms will reach the northern Miami Valley between 11 pm and midnight. So, yes this will be an overnight event. Showers and storms will continue down towards the Dayton metro between 1 and 2 am. Also, another thing to point out these storms will be moving sort of fast. Storms will push south of I-70 and start to diminish around 3 am. Stay with The Greater Dayton Weather Post for the latest information.
