A system tracking across the Northern Plains of the United States will bring another shot of snowfall to Southern Manitoba tonight and tomorrow.
A low pressure system in Montana has pushed snow into most of North Dakota and is beginning to push the snow northwards towards the International border. Snow should be slow to start this evening, with a dry northeast flow undercutting the moisture pushing up into Southern Manitoba, but by mid-to-late evening, the snow should have pushed all the way up to Winnipeg.
12Z GEM-REG Model Output Valid 12Z Sunday Morning (12H QPF)
Residents in Winnipeg can expect to see close to 5cm of snow fall on their freshly plowed streets, while areas closer to the border, such as Morden, Gretna, Altona, and Steinbach, will see closer to 7-10cm tonight. The show will be lighter tomorrow, with only another 2-4cm falling in most areas. Current indications are that this event won’t deliver warning-level amounts of snow; however people near the U.S. border will want to keep an eye on what Environment Canada does.
As the system moves out on Sunday, a concern again will be lake-effect snow flurries. The sudden onset of cold weather is allowing the lakes to produce heavy flurries giving near-zero visibilities at times. The exact location is too early to tell, however it looks like Winnipeg may be spared from them, with a more northerly wind expected behind the system.
After this, cold weather will return until mid-week, when it looks like there is another chance for snow.
Drive safe!
