Snow squalls could dump up to 15 centimetres of snow on Waterloo Region and other parts of southwestern Ontario by Tuesday morning – and that’s no April Fools joke.

Environment Canada has issued a special weather statement for Waterloo Region, Wellington County, the Bruce peninsula and the Owen Sound area, warning of potential snow squalls across that region.

The agency says there is not expected to be significant snowfall until after sundown Monday, though brief snow showers could create pockets of poor visibility and potentially slippery roads.

A more organized snow squall is expected to develop Monday evening and continue through the night.

The areas likely to be hit hardest include southern Grey-Bruce as well as the northern part of Wellington County and southern part of Dufferin County.

A snow squall watch is in effect for areas around Wingham, Listowel, Mount Forest, Arthur, Orangeville, Saugeen Shores, Kincardine and Hanover.

Environment Canada says up to 15 centimetres is possible in these areas by Tuesday morning, with the squall weakening but continuing to precipitate at that point.

High winds are also expected.
