About Tornadoes in Collinwood
This overview was written July 24, 2026. The tornado counts and notable-event figures elsewhere on this page reflect the latest data and may differ from this summary.
Collinwood is a neighborhood on the northeast side of Cleveland, close to the Lake Erie shore in a flat, densely built stretch of the Great Lakes lowlands. Northeastern Ohio experiences tornadoes as part of its warm-season severe weather, and while they are less frequent here than on the open plains, they are a real and recurring hazard.
The region's tornadoes form when warm, humid air moving up from the south becomes unstable under summer heating and a passing disturbance aloft adds wind shear. Nearness to Lake Erie can shape local storms — a cool lake breeze sometimes stabilizes the immediate shoreline, while boundaries between lake-cooled and inland air can focus thunderstorm development. Activity is generally greatest from late spring into summer, when the atmosphere is warmest and most unstable.
Tornado strength is described on the Enhanced Fujita (EF) scale, which grades a tornado from EF0 to EF5 by the damage it produces rather than a measured wind speed. The great majority of tornadoes here are weak, though stronger ones occur when conditions align. The specific tornado history near Collinwood — the total on record, the breakdown by decade and rating, and the deadliest, costliest, and most recent events — is drawn from the NOAA Storm Prediction Center and appears in the figures elsewhere on this page.
