A record snowfall, a.k.a., "snowmageddon," occurred from Dec. 4-8, 2010, affecting Huron and Middlesex counties in southern Ontario. A total of 177 cm of snow fell during a 102-hour period -- falling in 98 of those hours.

In a Toronto Star article, Environment Canada senior climatologist Dave Phillips told the media outlet there’s never been a month when Lucan has had more snow than what fell over the 4.5 days in December 2010.

It was a textbook lake-effect storm, where warm Lake Huron water met cool December air and was carried over the area by winds from the west, he said. What made this storm unique were the winds “caught in a rut” with no other weather pattern to push them out of the way, so it snowed 98 out of 102 hours since the storm began.

Driving was very dangerous on numerous roads because of high winds, prompting snow squall watches was for London, as well as St. Thomas and eastern Elgin County.

A multi-vehicle accident closed the westbound lanes of Highway 401 near Ingersoll, east of London. Seven tractor-trailers and up to four other vehicles were involved in the crash, police said.

Schools in London were closed Dec. 6 and 7, with public transit shut down until Dec. 9. All schools in Middlesex and Elgin counties were also closed during the same time period.
