Southern Ontario: Snow Squall Outlook for Tuesday, January 18, 2022

Forecast Discussion

Lake effect snow and localized snow squalls have developed off the eastern shoreline of Lake Huron and southeast of Georgian Bay tonight. They are expected to continue into early Tuesday morning bringing locally heavy snowfall to locations such as Kincardine, Goderich and Stratford. The bands are unlikely to get that intense so snowfall totals will mainly range between 5-10cm for most areas east of Lake Huron. Localized accumulation of up to 15cm isn’t out of the question if we see a squall lock in for an extended period of time, but it will be extremely isolated through somewhere in Huron and Perth counties. Regions southeast of Georgian Bay including Collingwood and Wasaga Beach will see lake effect flurries and periodic pulses of heavy snow adding up to at most 5cm. The lake effect snow machines will start to shut off later in the morning on Tuesday as a system approaches our region from the west.
