A low-pressure system is expected to bring significant snowfall to parts of southern Manitoba this weekend. 

As much as 10 to 20 cm of snow is possible in some areas as this system rolls through Saturday. 

The city of Winnipeg is currently under a special weather statement, while the southwest corner of the province is under a snowfall warning. 

"We have a system that is developing in Montana today, and it's going to track just south of the border and push heavy snowfall into  Alberta, Saskatchewan and into Manitoba, said Shannon Moodie, a meteorologist with Environment and Climate Change Canada. "We're expecting the snow to enter southwestern Manitoba this evening into the overnight. With that will be gusty winds, so blowing snow for them and pretty significant snowfall accumulations."

As for Winnipeg, Moodie says it's a little tricky. 

"We're really right on the edge of the heaviest snowfall. The snow for Winnipeg will be starting early Saturday morning. We're looking at 5-10 centimetres, so it's looking in that sweet spot of 8 centimetres. Our snowfall warning criteria is 10 centimetres in 12 hours. So we're really close to that criteria right now."

Either way, Moodie says Saturday, in general, will be an unpleasant day. 

The snow is expected to taper off Saturday night as the system rolls out of the province.
