Southern Ontario: Snow Squall Outlook for Friday, January 7, 2022

Forecast Discussion

Lake effect snow and snow squalls that brought over 20cm of snowfall accumulation to regions east of Lake Huron are expected to linger into Friday. The lake effect snow off Lake Huron has gotten fairly disorganized this evening but will reorganize overnight and into Friday morning. Current indications suggest a fairly intense band of snow setting up from Goderich and stretching into the Stratford and Grand Bend area. This will continue throughout the day before fizzling out just after the dinner hour. We could also see some scattered lake effect snow off the southern shoreline of Georgian Bay, but it shouldn’t be that intense.

When it comes to accumulation, we are looking at a general 10-15cm east of Lake Huron in addition to anything from Thursday. A few localized pockets could pick up as much as 20-25cm should a squall lock into a particular area for an extended period of time. The Collingwood and Meaford area can expect around 5-10cm of fresh snow on Thursday with locally as much as 15cm. We’re not expecting any significant snow for any other parts of Southern Ontario with just scattered lake effect flurries from the activity off Lake Huron and Georgian Bay.
