Saturday will bring another day of seasonably mild weather in Winnipeg, but a cold front sweeping through the province will usher in colder weather for Sunday.

Temperatures will climb near the freezing mark again today in Winnipeg as warmer air floods into the southern Prairies. The region will see mixed skies today and winds will persist out of the southwest in the 20 to 30 km/h range.

There will be a notable change in the weather this evening. A low pressure system moving through central Manitoba will sweep a cold front across the province overnight. The front will bring a band of snow that pushes from Parkland Manitoba this early into the Red River Valley before midnight, then to the Ontario border by Sunday morning. Behind the front, moderate northwest winds up to 40 gusting 60 km/h will usher a colder air mass into the region. A few flurries may linger across the region overnight behind the front. Temperatures will fall to a low in the -5 to -10 °C range.

On Sunday, the northwest winds will continue across the region as temperatures continue to fall through the day. Skies will clear by the afternoon with temperatures dropping into the -10 to -15 °C range. With clear skies and winds diminishing, temperatures will drop further into the -15 to -20 °C range on Sunday night.

The cool temperatures will continue on Monday with sunny skies and a high in the -5 to -10 °C range. On Monday evening, a warm front will push eastwards across Manitoba, bringing some more snow as a milder Pacific air mass pushes back into the province.

Long Range Outlook

We could see some snow in the Red River Valley early Tuesday, but much of the snow should fall to the north and east. Temperatures will rebound into the -5 to 0 °C range for Tuesday afternoon.

The region should be another day with above-seasonal temperatures on Wednesday, then a return to seasonal values for the rest of the week.

Today’s seasonal daytime high in Winnipeg is -5 °C while the seasonal overnight low is -14 °C.
