Flash Flood — Jun 26, 2025
During the evening of June 24th, a front wavered in a north-south manner in vicinity of Lake Erie while separating a very warm and humid air mass to the south from a somewhat cooler and less humid air mass to the north. Along and near the front, scattered multicell showers and thunderstorms persisted generally eastward across northern Ohio amidst moderate effective bulk shear and primarily mode...
Flood — May 9, 2021
A surface area of low pressure tracked from the high plains crossing northern Ohio on Sunday May 9th. Widespread light to moderate rain developed Sunday morning and was ongoing through much of the day. Temperatures were in the upper 30s to low 40s, and some snowflakes mixed in midday. As the system moved east, rain turned to snow in the primary snowbelt with reports up to 2��� in northwes...
Flash Flood — Jun 21, 2020
Low-level convergence along an eastward-moving surface trough axis contributed to the development of scattered thunderstorms over northern Ohio during the afternoon and early evening of the 21st. Vertical wind shear was weak. However, moderate instability and DCAPE amidst steep low-level lapse rates near 7.5C/km to 9.5C/km allowed multiple thunderstorms to generate damaging straight-line winds....
Flash Flood — May 26, 2018
Diurnal convection was being supported by the passage of an upper level shortwave on the evening of May 26th. The environment was favorable for heavy rain with high moisture content in the airmass. Flooding occurred over portions of Holmes County Ohio as storms merged and stalled over the central part of the county while producing torrential rainfall rates.
Flash Flood — Jun 22, 2018
An area of low pressure over western Indiana was slowly drifting towards northern Ohio on the afternoon of June 22nd. A series of lines of convection rotated into central Ohio from the south. These storms had heavy rainfall, which for most areas only lasted around 15 minutes. A slower moving north-to-south oriented line was extending over Wayne through Coshocton Counties. Flooding resulted over...
