Severe Weather - June 9 & June 10, 2020
On the afternoon of June 9th, the remnants of Tropical system Cristobal tracked through the mid-Mississippi River Valley, with some bands of thunderstorms developing on its eastern periphery in the Ohio Valley. These thunderstorms mainly impacted portions of east-central Indiana and western/southwestern Ohio and northern KY with a few strong wind gusts and reports of sporadic tree damage.

A more widespread severe weather event unfolded the next afternoon, on the 10th, as an unseasonably deep upper-level trof ejected east into the Ohio Valley amidst a very warm and tropically-moist airmass that had settled into the region. With unseasonably wind fields collocated with a seasonably unstable atmosphere, the environment was primed for widespread severe storms. Several linear clusters tracked east through the local area during the afternoon and evening, bringing with it widespread swaths of damaging wind and numerous observed reports of winds in the 50-65 MPH range. There were likely instances of even higher wind that were not directly sampled. The storms produced over 50 reports of wind damage throughout the local area.
