There’s a warm spell developing for next weekend, in fact there’s going to be a yo-yo of temperatures for the month of December, from below average to normal to above average, but first we must deal with a possible 20 cm of new snow until Thursday.

Environment Canada has issued, yet another snow squall watch for the area. Expect to see white outs and blowing snow with periods of snow squall bands affecting the snow belt areas of the district today.

Snow squall watch in effect for:

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

Snow squalls have developed over eastern portions of Lake Superior. They are expected to intensify this morning when winds become northwesterly. Snow squall warnings are in effect for areas just north of Sault Ste Marie. But as the northwest winds develop, these bands will begin shifting southward later today when they will potentially target Sault Ste Marie and possibly Manitoulin before weakening Thursday morning.

Under the snow squall bands, visibilities will be significantly reduced due to the heavy snow combined with blowing snow, and snow will quickly accumulate at a rate of up to 15 cm every 12 hours.

Snow squalls cause weather conditions to vary considerably, changes from clear skies to heavy snow within just a few kilometres are common. Public Safety Canada encourages everyone to make an emergency plan and get an emergency kit with drinking water, food, medicine, a first-aid kit and a flashlight.

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.
