Flood — Feb 17, 2022
A southeastward-moving surface cold front across southern Lower MI and northern IN approached northwest OH during the early morning of the 17th. The surface pressure gradient tightened in northwest OH as the cold frontal surface trough interacted with a surface ridge axis that remained anchored near the coast of the Carolinas and Georgia. This tightening surface pressure gradient and apparently...
Flash Flood — Sep 4, 2022
A surface cold front moved south-southeastward across Lake Erie and northern Ohio during the late morning through early evening of the 4th. Isolated to scattered showers and thunderstorms occurred along and ahead of the front, within a humid warm sector comprised of weak to primarily moderate MUCAPE and moderate effective bulk shear. Radar data suggest the weak and brief tornado was spawned by ...
Flash Flood — Jul 16, 2021
A cold front moved southeastward from Lower Michigan to Lake Erie during the evening and overnight of the 15th and then stalled in vicinity of the southern lakeshore by daybreak. This was in response to one surface low moving northeastward from southwestern Quebec toward the mouth of the Saint Lawrence River, while another low moved along the front from eastern Iowa to near the Michigan/Indiana...
Flood — Jun 4, 2020
A stationary front lingered along the US 30 corridor in northern Ohio. Afternoon and early evening thunderstorm development occurred along and near the front. Some storms produced heavy rainfall and isolated minor flooding. There were also reports of damaging wind gusts and quarter-size hail.
Flash Flood — May 28, 2019
An area of low pressure over Ohio drifted northeast driving a weak cold front south into the area in the evening. A lake breeze set up a convergence zone inland which enhanced storm development. Storms were slow movers and had rainfall rates around 2 inches per hour. This produced localized flooding in some areas.
