A weak weather system will track into central MB tonight and into northwest Ontario Tuesday morning. This system will bring a few showers through the northern interlake and central MB regions tonight possibly mixing with some wet snow in places. As the system tracks into northwest Ontario Tuesday morning, gusty northwest winds will develop behind the system over southern MB with northwest winds of 40 to 60 km/h possible through midday Tuesday.
By Wednesday a more potent system coming off the Pacific is forecast to track across far northern SK moving north of the MB/NU border on Thursday. This system is forecast to deepen into an intense storm over Hudson Bay on Thursday into Friday, with very strong northwest winds and blizzard conditions possible over the Hudson Bay coastline including Churchill and much of the Kivalliq region of Nunavut. South of this intensifying storm system, gusty south to southwest winds will bring milder conditions over the southern Prairies by Wednesday with temperatures climbing to the 20 degree mark over southern SK and southwest MB on Wednesday. Look for gusty southerly winds of 40 to 60 km/h or more over the Red River valley on Wednesday with highs in the mid teens. The milder weather will be short lived however as gusty northwest winds on the backside of the intense Hudson Bay storm drives cooler weather across the eastern Prairies for the end of the week.
