A winter storm warning has been issued for Guelph, the Waterloo region and parts of Wellington County by Environment Canada.
It has also issued a blizzard warning for the northern end of Wellington County, including Mount Forest and Arthur.
The weather body is advising holiday travellers to consider postponing road-trips until conditions improve.
The storm warning says that the area could begin to see some snow or rain arrive on Thursday afternoon or into the evening, which will turn into rain overnight.
The forecast from Environment Canada calls for wind gusts of 90 to 100 km/h and snowfall amounts between 5 and 15 cm by Friday night. Flash freezing is also possible on Friday morning as temperatures drop overnight Thursday.
“If visibility is reduced while driving, slow down, watch for tail lights ahead and be prepared to stop,” the weather statement warns.
“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.”
For those hoping to fly this weekend, airlines are advising travellers to check their flight status before heading to the airport. As winter storms impact other areas in Canada and the United States, planes have been grounded, causing ripple effects of further delays around the country.
