Wider weather episode

A well-organized upper shortwave trough crossing the western Great Lakes and Ohio River Valley and associated cold front crossed the region. Warm, moist conditions across the Ohio River Valley along with limited cloud coverage resulted in increasing instability (2000-3000 J/kg) over the course of the day. This along with increasing vertical wind shear up to 40kts (effective) as the trough and front approached from the west brought conditions favorable for severe weather by late afternoon / early evening. Damaging wind was the main threat with a notable mid-level dry layer, however, tornadoes were also possible.
