Just before noon on Thursday, Environment Canada issued a snow squall watch for North Bay, Powassan, Mattawa, West Nipissing and French River.
Environment Canada says that conditions are favourable for lake effect snow squalls from Lake Huron and Georgian Bay to develop overnight and continue into Friday.
Local snowfall amounts near 15 cm are possible in the heaviest snow squalls.
Travel may be hazardous due to sudden changes in the weather. Visibility may be suddenly reduced at times in heavy snow.
