A series of weak shortwaves in the mid-level flow lended support to thunderstorm development on August 20th.  Daytime heating was slowed by a cirrus shield earlier in the day, but later strong heating, continued moisture advection, and up to 30 knots of mid-level flow provided support for strong to severe thunderstorms.  Shear was weak overall, but the presence of ample downdraft CAPE supported a threat of wind damage from downbursts.
Storms forming in the mid to late afternoon hours, although becoming strong, did not produce any severe weather reports.  It was not until after 7 PM that storms were able to become strong enough to produce many reports of tree and power line damage.  The only report of structural damage was received from Guernsey County, where a large tree fell on to a home.
