UPDATE ON FORECAST SNOWFALL: Read the middle of the post please.
Well, looks like this winter isn’t done yet, I know a lot of you are royally tired of winter and I am too. I don’t like these long drawn out updates on winter weather but here I am again with another weather update to make sure that at the end of this you smile and leave informed. I am not a meteorologist but a weather specialist so I don’t have knowledge in exact details on this storm. That is why I write these updates. Anyways what we are expecting is a major Colorado low and this system will not only impact a large portion of southern Manitoba but it will have a variety of weather impacts. It’s clear Mother Nature is having a bad temper tantrum or she’s throwing a really bad late April fools joke on us. 😕😕.

For those that just want an idea of what the storm is expected to bring. Here’s info to make it easier for you to know what details are in this post: Details on day to day weather conditions. Storm timing and weather impacts. Snowfall totals and wind outlook.
Tuesday: A strong low pressure system will likely begin to develop south of the border, Tuesday will be a transition day with cloud cover increasing from the south ahead of the system. For those wondering the likelihood of significant winter weather likely won’t happen until at least Tuesday night. Temperatures on the day Tuesday will likely rise into the low to mid minus single digits (-1C to -5C).
Tuesday Night (Above): Much of southern Manitoba, will be included in the risk of increasing dangerous weather conditions by the morning hours. The Colorado low will be situated over Minnesota however the thing is with these systems is that they draw up moisture from the Gulf of Mexico and as a result the cold air on the backside of the system is entrenched in moisture and as a result can create heavy wet snow which will likely be the outcome of this system. Snow and blowing snow will begin lifting north of the border by the early evening to late evening and will likely occur as far north as highway 1 and the inter lakes into the southeast part of Manitoba, some areas of western Manitoba may see this system impact them as well. Models are predicting a northerly track which will reach as far North as the Ashern regions into central Manitoba. Highway conditions will be hazardous as the system hits our region. Overnight low temperatures will drop into the mid to high minus single digits (-4 to -7C).
Wednesday (Above): This is when the bulk of the system will impact the areas included in the southeast and interlake regions, winds on the backside of this system will likely be very strong given the fact tight isobars or thermal gradients will be in place. There is a risk as mentioned by environment Canada for blizzard conditions to develop in some areas of the red river valley on Wednesday or earlier. Snow will be expected to be the heaviest during the earlier part of the day, before tapering off to moderate snow by the afternoon and evening. Do not go out unless you have to , I won’t be volunteering at Siloam mission on Wednesday because of the storm. Temperatures on the day Wednesday will rise into the mid to high minus single digits (-5 to -2C).
Wednesday night (Above): Lingering snowfall will likely happen as this system begins to depart off to the east however, a strong northerly flow will still be present and there will be a risk for blizzard conditions or squalls. The good news is that it will begin to weaken as it moves off into Ontario and the eastern states as forecasted. Clear weather will be likely off in western Manitoba which will contribute to a cooler than expected overnight lows more typical of March where values will likely sit in the low to mid minus teens. 🥶🥶🥶. Areas further east under the heavier cloud cover can expect low temperatures in the mid to high minus single digits (-5 to -8C).
Overall Snowfall Totals: A majority of southern Manitoba will be seeing a heavy swath of snow. Main areas will likely get hit hardest from portage la prairie points east to the Ontario border north into the inter lakes where 15 to 25cm of snow could fall. 1PM Tuesday UPDATE ON SNOWFALL TOTALS: West/Southwest Manitoba, 5-10cm. Lake Manitoba to Pilot Mound and Killarney 10 to 15cm of snow. Red River valley, interlakes and Winnipeg to Emerson as far east as Beausejour and Steinbach 15-20+cm. White shell and Sprague 25 to 30cm of snow likely.
Higher amounts are likely south of the border. Have a look with that information here: https://www.pivotalweather.com/model.php?m=nam4km&p=sn10_acc-met&rh=2023040400&fh=loop&r=ca_c&dpdt=&mc=
Thursday: The winter storm should be out of our region by Thursday morning, with most of our region seeing sunny skies. A large area of our area will likely see temperatures in the low minus single digits. With overnight lows in the low to mid minus teens and high minus single digits. (-8C to -14C).
Friday and the weekend: Temperatures will return to a more normal level by Friday and for the weekend. With overnight low values in the mid to high single digits and above zero for overnight low temperatures.
