Miami Valley , Whitewater Valley, and the I-71 corridor of Ohio/Indiana:
A few pop up showers and storms are possible this afternoon before things dry out and cool down tonight as a front settles and stalls near the Ohio River. This same front will lift North putting the area back into an unstable air mass during the day Wednesday. This will set the stage for a potential Derecho. This is a large complex of storms that arrives late afternoon and last into early night with very strong winds, large hail, and heavy rains. These types of complexes can cause significant wind damage across large regions. They are also know to produce a few tornadoes on their Southern flank especially if any Super-cell thunderstorms can form ahead of them. Stay tuned for further details on this developing situation.
Cool air rushes in behind Wednesday's system bringing pleasant sunny weather through the early part of the weekend. Another system brings more scattered showers and storms Sunday and Sunday night before more cool air returns.
