Significant Colorado Low Set to Slam Southern Manitoba

 Southern Manitoba will likely get impacted by a significant Colorado Low Pressure system over the next 24-48 hours. Unfortunately it looks like this system might stick around until at least Thursday. This system will have significant impacts, a batch of freezing rain ahead of the system went through southern sections of Manitoba during the overnight period into the morning today, and it’s beginning it’s impacts on southern Manitoba. This may end up being the first significant storm of the 2022-2023 winter season. Read on to find out more. 

Tuesday: Much of the day will remain cloudy and mild as we sit in the warm sector of the low pressure system, for those who sit around today wondering where all the snow is. It’s on the way. Today will be the calm before the storm, much of the snow at the moment is spiraling over northern North Dakota with snow lightly falling in western Manitoba. Winds will be light out of the south today with temperatures soaring into the high minus single digits, areas in western sections of Manitoba may see highs in the mid minus single digits. 

Tuesday Night (See above for reference): Heavy Snowfall will begin to develop over southern sections of Manitoba tonight, most of that will likely start by at least 9pm to midnight. Conditions will begin to deteriorate rapidly, snow and blowing snow will start mainly along and north of the international border. It’s hard to tell where the heaviest snowfall will occur, there’s a chance it stay’s stateside or lifts north of the border slightly. By morning it will finally reach the northern red river valley and the interlakes. This will be a multi day event so I will post snowfall totals expected at the end of this summary for the storm. Temperatures will drop into the low minus single digits.  So not a lot of cold weather expected. 

Wednesday: Snowfall will continue across much of southern sections of Manitoba this will likely move into the interlakes, parklands and much of northern Manitoba by the afternoon. Travel isn’t advised during the day on Wednesday. (See Photo for snowfall imagery above). Mild temperatures will continue for us, and bizzare enough that they will rise above zero for extreme southern parts of Manitoba near Winkler. 

Snowfall Totals: Southern sections of Manitoba especially along the American border may see as much as 20 to 30cm of snow including western portions of Manitoba. Areas along and north of highway 1 will see upwards of 10 to 20cm especially in areas of western Manitoba. Amounts will vary and if the snowfall area shifts the heavy amounts could very will shift . 

By the end of the Storm, including additional snow that falls on Wednesday night and Thursday a total of 10 to 15cm can be expected along and north of the Trans Canada Highway. 

Wednesday Night: Much of the southern sections of Manitoba will likely experience blowing snow continued with the low sitting over southern Minnesota. A brief reprieve from snow will happen heading into the overnight period before another batch of snow moves in from northwestern Ontario by morning. Temperatures will remain on the mild side as most areas only see lows in the low to mid minus single digits (-2 to -5C). 

The second Half of The week: Remnants of the low pressure system will begin to move east, and more snow and light snow will impact southern sections of Manitoba with another 2-5cm of snow likely into Friday. Temperatures will begin to drop on Thursday with highs in the upper minus single digits with the same on Thursday night. Friday and Friday night lows will drop into the high minus single digits and low minus teens right behind the low.
