It should be a smooth drive Thursday morning but the first major snowfall is expected to make landfall Thursday night.
A snow squall warning is in effect across the area with as much as 20cm of snowfall expected by Friday night starting on Thursday.
Drivers can expected reduced visibility at times in heavy and local blowing snow with more heavy snowfall expected into the weekend and early next week.
Lake effect snow off Lake Huron is forecast to develop tonight and will persist through the weekend and into early next week.
As is common with lake effect snow, snowfall amounts will be highly variable.
Some areas may receive in excess of 50 cm by the end of the weekend.
Road closures are possible this weekend especially over areas that receive multiple snow squall bands.
Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Travel may be hazardous due to sudden changes in the weather.
