Miami Valley , Whitewater Valley, and the I-71 corridor of Ohio/Indiana:
Hazardous Outlook: There is the potential of a few strong to severe thunderstorms along a potent cold front late in the day tomorrow. Given thick cloud cover there will be a limit on how much heating the region will see. If the sun can get through and allow for some warming tomorrow there will be more instability to work with. However given a strong and dynamic wind field of this system combined with higher dew-points for this time of year there may be a strong line of showers with a few embedded super-cell thunderstorms that may tap into this wind field and bring down damaging gusts. There is a 3 out of 10 chance that any of one of these thunderstorms may produce a tornado as there will be plenty of wind shear available. Some storms may also produce locally heavy rainfall. Stay tuned for further details.
Even with out thunderstorms there will be strong wind gusts to 50 mph just ahead and along the cold front.
