Snow Squalls Adding to Snow Totals


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 squall watch in effect for:

  • Agawa – Lake Superior Park
  • Sault Ste. Marie – St. Joseph Island
  • Searchmont – Montreal River Harbour – Batchawana Bay

A northwesterly flow off Lake Superior and Whitefish Bay will continue to produce multiple bands of lake effect flurries today. The flurries are expected to intensify near midday over the Sault Ste. Marie area with snow squalls possible into the evening. Local snowfall amounts of 10 to 15 cm per 12 hours are possible. As winds become more westerly tonight, the threat of snow squalls will move north of the Sault Ste. Marie area affecting areas east of Lake Superior into Wednesday.

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 suddenly reduced at times in heavy snow.
