Below Seasonal Temperatures ahead, after early week snowfall

 Much of southern sections of Manitoba and our region will be impacted by yet another Alberta clipper, 🤦🏻‍♂️ however this one will only make significant weather in Northern Manitoba and portions of central Manitoba into the interlakes mainly. There will be southward extending impacts such as light snow and strong winds. This system unfortunately will mark a transition over to a weeks worth of cold weather, and maybe longer. Read on to find out if minus twenties or minus thirties are in store. 

Tuesday: During Tuesday morning into the afternoon we should see the waning impacts of a low pressure system as it moves out of the province into Ontario, northwesterly winds gusting to 50km/h should abate by the late morning and early afternoon to light. Snow and light snow will continue throughout the day into the early evening hours, with general amounts of 2-4cm. Temperatures during the day will rise to the mid to high minus single digits with some areas in the parklands seeing highs in the low minus teens (-4C to -12C). Windchills will however sit in the mid to high minus teens , with low minus twenties possible in the parklands regions in small sections (-16C to -21C). Tuesday Night: Cloudy skies and light snow may persist until shortly after midnight in some sections. Generally partly cloudy skies are expected overnight with clear skies in some places at times. Overnight lows will drop into the mid to upper minus teens (-15 to -18C) eastwards away from the west and interlake regions, parts in the southwest to just west of Winnipeg and all points north will see lows in the low minus twenties (-20 to -25C). Windchills accordingly will likely drop into the mid to high minus twenties for most and the low minus thirties in the southwest and western portions. (-25 to -32C). 

Wednesday: During the afternoon a large area of high pressure will drift south into the western Canadian prairies. Sunny to partly cloudy skies are likely this will unfortunately prevent our daytime high temperatures from rising to our normal day time averages, we will likely be seeing high temperatures rise into the mid to high minus teens, (-14C to -17C) with windchill values sitting in the low to mid minus twenties (-21C to -26C). 

Wednesday Night: Much of the region will unfortunately see a significant drop in temperatures with areas seeing lows in the mid to high minus twenties (-24C to -29C), and windchills in the low minus thirties with a high minus thirties values being reached at some point (-32C to -36C). The fact that clear skies are gonna be in play there’s a risk that temperatures could drop below minus 40C but I don’t see that being likely. 

Thursday: Another clipper system 🤦🏻‍♂️🤓🤓 will probably come into the province bringing another round of snowfall, it’s hard to tell right now if the system will bring a risk of blizzard conditions. At the moment a general 5cm can be expected with lesser amounts in other areas especially the western half of Manitoba. Temperatures during the day will rise into the low minus teens (-10 to -12C), with the windchills likely sitting in the mid to high minus teens (-15C to -19C). Everyone will be between those values. I just also looked at the isobarbs after the system passes through and it seems there  could be a risk of a blizzard late Thursday. 

Update coming on Thursday evening or Friday.
