Discussion :

  
Low pressure in the Dakotas pushes cloud and showers into southern MB today, with a risk of thundershowers for southeastern areas where temperatures are warmer below the upper warm front. Saturday looks cool and cloudy with a northerly flow between surface ridging to the west and the low in northern ON.

Remarks :

  
The Canadian model is alone with bringing a surface low up though MB from Sunday to Tuesday with widespread showers, while other models track it northeast into Ontario in which case just southeastern MB sees good precipitation on Sunday, with light showers/drizzle for eastern areas on Monday. Either way temperatures remain seasonally cool, humidity high and skies on the cloudy side.
