The bitter cold temperatures are gone, but a quick moving Alberta Clipper will bring some snow to the Sault for Sunday .Temperatures are expected to rise to plus 4c by this Wednesday. Snow squalls are developing off Lake Superior Sunday.
8:15 AM EST Sunday 07 January 2018
Snow squall warning in effect for:
Searchmont – Montreal River Harbour – Batchawana Bay
Snow squalls are expected. Under the snow squall bands, visibilities will be significantly reduced due to the heavy snow, and snow will quickly accumulate.
Snow squalls from Lake Superior are expected to develop late this morning.
Local snowfall amounts of 15 cm in 12 hours are possible. Snow squalls may persist into Monday.
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. Be prepared to adjust your driving with changing road conditions.
Snow squall warnings are issued when bands of snow form that produce intense accumulating snow or near zero visibilities.
Snow will affect all of northeastern Ontario today and tonight.
However, bands of heavier snow will develop in a strong southwesterly flow off of Lake Huron with areas of reduced visibilities in snow and blowing snow. Rapidly accumulating snow could make travel quite difficult in some locations.
Along Highway 17, the most affected locations in these Lake Huron bands will be between Massey and North Bay and Highway 69 between Sudbury and Bayfield Inlet.
Meanwhile, Sault Ste. Marie will be affected by snow off Lake Michigan until later this afternoon.
Snowfall totals off Lake Huron may reach 15 to 20 cm in a few locales over the next 24 hours, however the snowfall warning criteria of 15 cm in 12 hours is not expected to be reached.
It is recommended to adjust travel plans accordingly.
