A moist and unstable airmass was in place ahead of the front and severe thunderstorm watch #628 was issued for Northwest Ohio, followed by severe thunderstorm watch #629 for North Central and Northeast Ohio.  A few thunderstorms produced wind damage with numerous reports of penny to quarter size hail.
