A lake breeze kicked off a pulse severe storm in Oakland County to start things rolling on Tuesday, May 30th. With a very unstable airmass in place, additional strong thunderstorms were able to develop on the outflow boundaries from previous storms. This led to severe thunderstorm development propagating as far north as Huron County. At the same time, another line of severe storms, that had initially formed along a lake breeze off of Lake Michigan, tracked across the Tri-Cities area. There were numerous reports of large tree limbs and trees downed. Also, several hail reports were received, with the largest hail being reported as the size of quarters.
