Episode Narrative Broad ridging was in place across the Mississippi Valley on the morning of the 7th, with the Upper Ohio Valley region experiencing WNW flow aloft. After morning showers and thunderstorms moved across the area due to a warm front, the upper level flow regime brought an elevated mixed layer (EML) into the region during the afternoon, capping convection during the afternoon and early evening hours.
Convective clusters over Michigan during the evening congealed into a mesoscale convective system (MCS) and raced across Lake Erie, arriving in the NWS Pittsburgh forecast area shortly before midnight. Steep mid-level lapse rates thanks to the EML allow for a few large hail reports initially. However, the main impact of the system would be from wind. Surface temperatures surged into the low to mid 60s ahead of the line on gusty southwest winds, resulting in surface CAPE of 1000 J/kg and a significant curving/lengthening of the hodograph. With the boundary layer no longer decoupled, strong ambient mid-level flow combined with highly efficient evaporational cooling in the convective downdrafts allowed substantial downdraft CAPE to be realized with surface wind gusts exceeding 70 mph observed and evident over a wide area given the volume of wind damage reports. Embedded vortices in the quasi-linear convective system also led to five tornadoes in the EF0/EF1 range during this event across the region, with three of these impacting east-central Ohio. Numerous instances of tree and structural damage were observed across the region.
Event Narrative A continuous swath of tornadic damage was encountered beginning just north of Route 558 near Hawkins Rd. and ending along Carmel Achor Rd just west of Route 170. The tornado snapped or uprooted numerous hardwood and softwood trees, causing several to fall on structures and power lines. Although many of the mobile homes encountered along the path were spared direct wind damage, it is suspected that the trees surrounding them absorbed much of the wind and spared the homes damage from the strongest wind.
A few outbuildings of varying degrees of structural integrity suffered damage as well. In multiple cases, metal roof panels were ripped off. In another, a particularly well-built small shed lost several shingles and a piece of roofing. A less-sturdy but medium-size outbuilding collapsed when its north-facing wall caved in.
In several focused spots along the path, concentrated, near-total tree damage was encountered consistent with EF1 wind speed (90 mph). Much of the remaining damage was consistent with 70-80 mph wind.
