Major Winter Storm to Start the Week

A major winter storm will impact all of Southern Manitoba to start the week. Accumulations will be very heavy in some areas, but luckily this won’t be another blizzard.


Weather Conditions at 12pm on Monday (GEM-Regional)

A developing low pressure system currently located in south-western Saskatchewan will be responsible for the snow. This system was formed as a powerful upper-level disturbance moved onshore in British Columbia late last night. This disturbance continues to track across the Prairies and will provide the lift necessary to generate the snow.

The snow has already begun to fall in south-western Manitoba this evening. Bands of moderate to heavy snow have been falling just south-west of Brandon. Heavy snow will continue to develop in this region as the evening progresses. Further east in the Red River Valley snow will begin to fall gradually this evening, with heavier bands moving in overnight. By Monday morning all of Southern Manitoba will be in the snow. It is expected that the heaviest snow will fall mainly south and west of Winnipeg, particularly along the international border, though the city will see decent accumulations as well. The following graphic shows our snowfall forecast for Southern Manitoba:


Snowfall totals by Tuesday morning across Southern Manitoba.

The wind through this event won’t be particularly strong, with speeds of 20-30km/h gusting to 40-50km/h expected during the day on Monday. This will cause some blowing and drifting snow on the highways, but within urban areas the wind won’t be a significant factor. Temperatures through the day on Monday will be fairly steady in the mid to upper minus single digits, so the wind chill won’t be very high either. The snow will taper off on Tuesday night, with only lingering flurries expected by daybreak on Tuesday.

Tuesday will see our weather begin to settle down as the storm departs. As mentioned above, we may see a few flurries during the day on Tuesday, but additional accumulations will be small. Temperatures won’t drop off much, with highs once again in the mid to upper single digits.

Wednesday will again be a rather unexciting day weather-wise. Temperatures will be in the mid to upper minus single digits with a brisk south-easterly wind.
