Snowstorm possible by Monday.. followed by another cold blast next week.

Just a heads up that models are hinting at our first significant snowfall of the month over Winnipeg and Southern MB by next Monday with 5-10 cm possible. Snow has been scarce this month over the Winnipeg area with only about 3 cm so far this month. Milder temperatures will be associated with this next system with temperatures possibly reaching -5C by Monday. However, models are indicating a return to below normal temperatures by Tuesday or Wednesday in the wake of this system, as northerly winds usher in another blast of Arctic air from the northwest. Will keep you posted on this developing situation in the days ahead..

In the meantime, enjoy the break from the cold snap over the next few days as the Arctic airmass moves east and moderating temperatures move in from the west. Brisk southerly winds on Thursday will begin bringing in that milder air, but those gusty south winds will make the afternoon high of -15 feel considerably colder. Friday looks much nicer as sunshine and light winds make highs of -15 feel milder. Thus, even though similar temperatures are forecast for Thursday and Friday, Friday will seem much milder due to to the lack of wind.


  1. It looks like that 5-10cm of snow will be coupled with very strong winds. This could create blizzard conditions, and close highways.

    As with most forecasts they can still fall through, we are basing our predictions on computers thoughts after all.

  2. Latest models coming more in line with Monday's storm.. taking a strong low over western North Dakota and moving it over Lake of the Woods by Monday evening. This would bring significant snow and blowing snow through much of southern MB, especially western MB and eastern SK spreading eastward into Winnipeg/SE MB by Monday night. This event of course is still a few days away and there will likely be changes in forecasts of storm track, intensity and timing, but this is a storm that bears watching. Will be an interesting start to the work week!

  3. Finally we can get some interesting weather to talk about! I would imagine it makes your job much more exciting when there is interesting weather to forecast.
