Thunderstorms Produce Hail and Wind
and One Tornado

moderate risk area over northern OH

The day began with an outlook for a moderate risk of severe storms from the Storm Prediction Center (SPC). The concern was with a deepening area of low pressure that was going to track toward northwest Ohio. A warm front was situated across northern Ohio and was expected to provide a focus for storms. There was a threat for a few tornadoes along with storms that would produce hail and damaging winds.
mesoscale discussion A dying complex of thunderstorms during the morning delayed the warm-up, but by afternoon temperatures were reaching the upper 70s. Dewpoints, a measure of the amount of moisture in the air, were reaching near 60 degrees. After coordination with SPC, a Tornado Watch was issued for the evening.
The radar animation below shows the evolution of the line of thunderstorms out ahead of the cold front. This loop runs from 8 pm through 1 am. Click radar imagery below to enlarge. The first storms to initiate were discrete supercells in northwest Ohio. There was one storm that hugged the coast line from Sandusky to Cleveland and another that formed across northern Wood county and moved east to Huron. Later a few bowing segments developed as the line of thunderstorms filled in and moved eastward.

Hardest hit areas included locations from southern Wood county across Erie county and finally into Cuyahoga county. Click radar imagery below to enlarge. Early in this zoomed in radar loop, a supercell can be found moving from just south of Sandusky to Huron and Vermilion. It has a classic "hook" shape to it. This storm moved into Lakewood and Cleveland producing more damage. While no tornado developed from this supercell, there were plenty of large hail and strong winds reported.
