Forecaster: Brennen Perry

A fairly intense snow squall is expected to develop off southeastern Georgian Bay around 10-11 am Tuesday and stretch inland around Wasaga Beach to as far as Bradford throughout the afternoon. Snowfall rates will be quite heavy at times getting close to 5cm/hour in the strongest part of the squall. Very dangerous travel conditions can be expected within the affected region as squalls can produce sudden whiteouts with little warning not to mention the extensive snowfall accumulation. The lake effect activity will continue into the evening hour although the main squall will weak somewhat with the development of multiple unorganized bands. Overnight we should see the squalls retreat close to the shoreline around Collingwood before slowly fizzling out by sunrise on Wednesday. Accumulation will vary significantly across the region, but it wouldn’t be a surprise to see some localized accumulation of over 50cm by Wednesday morning. Current indications suggest the potential for 50+cm exists just northwest of Barrie around Wasaga Beach although a slight shift in the location of the squall may put the City of Barrie in the bullseye. Accumulation will drop off quite fast as you move away from the southeastern shoreline of Georgian Bay.
