Snow squall watch in effect for:
- Barrie – Collingwood – Hillsdale
- Midland – Coldwater – Orr Lake
- Orillia – Lagoon City – Washago
Lake effect flurries and local snow squalls are expected to develop late this afternoon and shift through the region tonight. Snowfall amounts of 10 to 15 cm will be possible under the most intense bands.
The squalls are forecast to persist through Friday in some areas.
Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Visibility may be suddenly reduced at times in heavy snow. Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow.
