Get ready for our first blast of cold air this season by early next week. A developing low pressure system over the Pacific will move across southern AB and track across the southern Prairies Sunday into Sunday night. This system will bring cold northwest winds behind it which will sweep across southern MB Sunday night into Monday. The cold air will be well entrenched across southern MB Monday and Tuesday with daily highs struggling to get above freezing, along with cold northwest winds. In addition guidance suggests this system has the potential to bring the season's first accumulating snow across southern MB Sunday night depending on the eventual track of this system. Models bring an east-west swath of snow anywhere from North Dakota through central MB, with local amounts of 5 cm possible.
Dry but cool weather is expected through the middle of next week before a potential for another snowfall late next week into next weekend. Looks like winter will finally be making an appearance next week over Southern MB!
