Environment and Climate Change Canada has issued a special weather statement for all of Southern Manitoba.
Senior climatologist David Phillips says a Montana low will bring a significant amount of precipitation.
"I think in Western Manitoba, it will be mainly a snow event. I think there is some issue in the Red River valley as to whether or not there will be some rain or maybe even freezing rain as part of this as well. And we are talking about 20 to 30 cm of snow."
Phillips says this is shaping up to be one of the biggest storms to hit our province this winter.
"Certainly for western parts of the province, it is going to start clouding over on Saturday morning, and as the system comes through there will be some flurries possible on Saturday evening. But it will principally be a Sunday event - an all-day snow event."
The snow is expected to start sometime late Saturday evening and could be accompanied by winds gusting at times as high as 80 km an hour on Sunday.
