April 29, 2014 Severe Weather - Damaging Thunderstorm Winds
An area of strong to severe winds associated with a cluster of showers and thunderstorms moved from northern Kentucky
to central Ohio during the late afternoon and evening of April 29, 2014. A small bow echo became evident in radar
reflectivity with the corridor of strongest winds as the storms traveled northeast.
There are several interesting things to note in this radar imagery:
Initially the reflectivity values are fairly weak (more greens and yellows). However, the atmosphere was conducive to strong thunderstorm downdrafts.
There is an eastward transfer of the strongest storms over southwest Ohio. This occurred as the thunderstorm cold pool organized and tracked toward a region of higher downdraft instability. Afterward, a more pronounced "bowing" structure develops.
An outflow boundary from previous rains existed over the Scioto Valley. As the existing bow intersected this boundary, it strengthened, and new storms fired instantly along the colliding boundaries in Franklin, Pickaway, and Ross Counties. While severe weather was not produced southeast of the existing bow, heavy rainfall occurred as strong thunderstorm updrafts developed.
