Snowfall Amounts Received by Environment Canada as of 12 pm


A large disturbance tracking northeastward across the Great Lakes brought an early season snowfall to much of Southern and Eastern Ontario last night, turning a previously green landscape into a winter wonderland. Snowfall amounts of 5 to 10 cm were common in many areas, with amounts reduced to a trace of slush near Lakes Erie and Ontario where most of the precipitation fell as a cold December Rain. The highest snowfall amounts were observed in a swath from the Dundalk Highlands across Simcoe County into parts of Eastern Ontario, and at Sault Ste. Marie. Many thanks to all volunteer reports from Cocorahs, email, and social media. Snowfall amounts received by Environment Canada as of 12 PM are found in the table below.
