Snow squall watch in effect for:
Goderich – Bluewater – Southern Huron County
Listowel – Milverton – Northern Perth County
Stratford – Mitchell – Southern Perth County
Wingham – Blyth – Northern Huron County
Snow squalls are expected to develop. Under the snow squall bands, visibilities will be significantly reduced due to the heavy snow combined with blowing snow, and snow will quickly accumulate.
Snow squalls are expected to develop this evening.
Snow squalls and blowing snow will develop this evening and are expected to diminish late Thursday morning. Snowfall amounts of 15 cm per 12 hours are possible.
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 significantly and suddenly reduced to near zero. Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow.
Snow squall watches are issued when conditions are favourable for the formation of bands of snow that could produce intense accumulating snow or near zero visibilities.
