A snow squall watch remains in effect for Sault Ste. Marie – St. Joseph Island
Snow squalls continue in the westerly flow off Lake Superior. The winds will slowly shift to more northwesterly later today which will bring the threat of snow squalls into the region. Snow amounts of 5 to 10 cm per 6 hours are possible in the heaviest snow squalls. Low visibility in blowing snow will also be an issue with any squalls that affect the region. Snow squalls will move out of the region later tonight.
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.
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.
