Snow and blowing snow will continue today for the city of Sault Ste. Marie and the eastern shores of Lake Superior.
Snow Squalls began last evening as a cold front ushered in much colder air behind it. The Sault got off easy only seeing about 3cm overnight. Environment Canada is calling for a potential of 15cm additional today and lingering into the evening.
Some areas are seeing substantial snowfall from lake effect snow squalls. Highway 17 near Wawa remains closed at this hour. (8am)
Warmer air will move back in mid-week with rain showers only to see temperatures drop again with a promise of more snow squall activity on Thursday.
Snow squall warning in effect for:
Sault Ste. Marie – St. Joseph Island
Searchmont – Montreal River Harbour – Batchawana Bay
Snow squalls continue today.
Snow squalls are expected to continue today before slowly weakening tonight.
There is potential for local snowfall amounts of 15 cm or more per 12 hours in the strongest snow squalls, along with sudden near zero visibility in bursts of heavy snow and blowing snow. Total snowfall accumulations may reach 30 cm by the end of the event, especially if a snow squall can lock in over a particular location for a few hours.
Very strong northwesterly winds will also whip up freshly fallen snow and cause sudden near zero visibility from blowing snow in exposed areas at times.
Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow. Rapidly accumulating snow could make travel difficult over some locations. Consider postponing non-essential travel until conditions improve. Road closures are possible.
