It’s pretty safe to say that a White Christmas is guaranteed. More snow is on the way and it will come with bone chilling temperatures. An arctic cold front will push through starting Wednesday that will kick off potential snow squalls along the Lake Superior shoreline between Heyden and Wawa. However, there is a possibility that the squalls will move more southerly and impact Sault Ste. Marie Wednesday afternoon into the evening.
Environment Canada has issued a “watch” for the Superior East region.
Snow squall watch in effect for:
Agawa – Lake Superior Park
Searchmont – Montreal River Harbour – Batchawana Bay
Long lived snow squalls are expected to develop. Under the snow squall bands, visibilities will be significantly reduced due to the heavy snow, and snow will quickly accumulate.
A cold front will bring a fresh blast of Arctic air for Northeastern Ontario this morning. Behind this cold front lake effect snow squalls are expected to develop over eastern Lake Superior and will significantly impact travel in this area.
The heaviest snow squalls are forecast to develop later this morning and are not expected to end until Thursday morning. As a result, local amounts could be considerable.
Travel may be hazardous due to sudden changes in the weather. Road closures are possible.
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.
