UPDATE: 10AM Sunday
Environment Canada has now issued a Winter Storm Warning for the area.
A slow moving weather system approaching from southwest of the Great Lakes is expected to bring winter storm conditions today through Monday night.
Snow has begun near the eastern shores of Lake Superior and will spread northeastward through tonight.
Significant snowfall accumulations of 20 to 30 cm as well as brisk winds gusting up to 50 km/h will result in localized blowing snow and difficult travel conditions today through Monday.
Environment Canada will continue to closely monitor this situation and provide further updates as the storm evolves.
Consider postponing non-essential travel until conditions improve. Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow.
Winter storm warnings are issued when multiple types of severe winter weather are expected to occur together.
By the looks of, Winter will take one last punch and then be done. A series of low pressure systems have impacted Ontario this past week.
Southern Ontario is currently in the middle of a major ice event with snow, freezing rain , ice pellets and wind. Tomorrow is our turn as another system taping into a lot of moisture will hit the area. Anywhere from 5cm to 30cm can be expected. The chances of seeing more than 15cm sits at 37%.
Later this week, most of the snow will melt as more typical Spring weather will finally move in with forecast highs near plus 10c.

Winter storm watch in effect for:
Agawa – Lake Superior Park
Sault Ste. Marie – St. Joseph Island

Major winter storm threatening beginning Sunday.
A moisture laden low approaching from southwest of the Great Lakes is expected to bring a winter storm to much of Northern Ontario.
Snow is expected to arrive in areas near the Great Lakes starting later Sunday morning and will quickly spread northward into all regions during the afternoon.
Significant amounts of snow are expected. This type of storm generally tends to bring a snowfall of 20 to 30 cm with it. Snow may change over to ice pellets and freezing rain Sunday night into Monday over parts of Northeastern Ontario.
In addition, strong and gusty winds may whip up the freshly fallen snow resulting in blowing snow in exposed areas.
Travelling conditions will deteriorate quickly when the snow arrives on Sunday.
Avoid travel if possible. Surfaces such as highways, roads, walkways and parking lots may become icy and slippery.
