It’s been a snowy couple of days in Sault Ste. Marie but no where near as snowy as you may think.
According to Environment Canada , Sault Ste. Marie picked up about 23.1 cm since Thursday night to Friday night at midnight. That gives us a total of approximately 40 cm on the ground since we already had about 15cm on the ground before the storm hit.
Snow Squalls developed behind a low pressure system that brought harsh winter conditions to the American Midwest before entering the great lakes region Thursday night. Blizzard conditions were reported in parts of Iowa and Minnesota where over a foot of snow fell from this same system.
As the low tracked easterly, winds circulating around the low drew colder air over Lake Superior that developed in a full day of lake effect snow showers and snow squalls.
The snow squalls shifted north Friday night, reducing the amount of accumulation in the city, but north along the traditional snowbelts of Heyden, Goulais and Batchawana saw snow exceed 35cm Friday and will continue for part of the day today.
Sault Ste. Marie continues to be placed under a snow squall watch . It is expected the winds will shift the snow squalls back into the city for a brief period Saturday and again on Sunday.
If snow squalls do materialize , another 5 to 10cm can be expected by Sunday night.
Lake effect snow showers will remain a threat for most of the week as much colder arctic air settles in for about ten days plummeting our daytime high temperatures to around the -14c mark and very cold overnight temperatures in the -20’s . That’s well below seasonal values.
Last year, Sault Ste. Marie saw 86cm of new snow during the month of February. With the great lakes not frozen over this year, the threat of heavy lake enhanced snow showers could exceed that monthly total this year.
The record snowfall for this date was set in 2006, with 26.8 cm falling in a 24 hour period.
