Southern Ontario: Snowfall Outlook for Tuesday, December 28, 2021

Forecast Discussion

Light snow is expected to continue overnight into Tuesday morning throughout Eastern and Central Ontario. We aren’t expecting much in terms of snowfall accumulation with a centimetre or two of accumulation. We could see between 2-4cm across Sudbury, North Bay and Algonquin Park. Another system will skirt across Lake Erie late Tuesday afternoon which could bring accumulating snow to Deep Southwestern Ontario. Accumulation between 2-6cm is possible for the Windsor and Chatham-Kent area by the end of the day with the majority of the snowfall coming after the dinner hour. The moisture from this system isn’t expected to make it that far north. Roughly north of a line from Goderich to Toronto will see barely any snowfall from this system. Snowfall will taper off just after midnight as the system fizzles out.
