Waterloo Region will experience heavy snowfall on Saturday, with five to 10 centimetres of accumulation expected by the end of the day.

CBC meteorologist Ross Hull said though some flurries will fall through Friday, the real accumulation will begin on the weekend.

"Saturday, say around 10 a.m., you'll start to see some of that snow falling and the snow is going to intensify through the day on Saturday. So by the evening hours it will likely be a little more intense," said Hull. 

Environment Canada says "this could be the first significant snowfall of the season" for the area that includes Waterloo Region, Guelph, Erin, northern and southern Wellington County, Mount Forest and Arthur which to date have seen little snowfall.  

"At this point I'm pretty comfortable with [forecasting] five to 10 centimetres. That being said, it's not an epic snowfall event but with the wind, if you're travelling along the 401, local highways and so on, driving will certainly be tricky with reduced visibility at times with that snow blowing around,"  said Hull.
