Overview

A surface low pressure system from the Midwest moved east across the area on
Tuesday, August 6, along a stationary boundary that was draped across the region
for the majority of the day. Surface features were supported by an upper level
shortwave trough moving southeast across the region in addition to the CWA
being underneath the right entrance region of the upper level jet and vorticity
maximum. MUCAPE values across the area approached 3000 J/kg with shear
values of 30-40 knots as the LLJ pushed north across the area. Strong updrafts
were evident with ample moisture of dewpoints in the 70s and 0-1km helicity
values exceeding 100 m2/s2 to go along with steep low- level lapse rates. Hodographs supported supercell and tornadic potential near the boundary owing to the multiple tornadoes, marcobursts, and strong bowing segments observed during the event. Several tornadoes occurred throughout the CWA to include two high-end EF-1s, two additional EF-1s and a macroburst in Cuyahoga, Lake, and Geauga Counties.
