A strong area of low pressure was located over southern Lake Michigan during the early morning hours of December 11th. This low moved quickly northeast to north of Lake Ontario by mid-afternoon, deepening at a rate of almost 1 mb per hour. Ahead of this system, conditions were warm across the area with temperatures into the 60s in some locations during the early morning hours. As this low pressure system moved east, it extended a cold front across northern Ohio, which allowed for temperatures to crash significantly into the 30s. More importantly, this front also allowed for showers and thunderstorms to move ahead of it through the region early in the day. Behind the front, strong synoptic winds moved across the region with the pressure rises behind the system. Wind gusts as high as 64 mph were felt across the area with that highest report recorded by a trained weather spotter with well sited equipment on the southeast side of Parma. Minor damage occurred across the region with downed trees and power lines and poles, which prompted numerous outages. Some minor structural damage was also noted in some locations.
