A low pressure system crossing the Prairies will bring more snow to Winnipeg and area this weekend, but its cold front will usher Arctic air back into the region.

A cold front slumped through the region yesterday evening, northerly winds and cooler temperatures for the end of the work week. Daytime highs in the Winnipeg area will sit in the -20 to -15 °C range today as north winds of 20 to 30 km/h gradually ease. The seasonably cool weather will at least come with sunny skies.

The weather will turn this evening as a low pressure system building into the Prairies pushes cloud over into the region. The cloud cover will help keep temperatures warmer tonight, with lows staying on the warm side of -20 °C before beginning to warm overnight. A warm front will push into the region overnight, bringing some light snow into the region.

Heading through the weekend, a couple waves of light snow will move through Winnipeg with clouds and flurries between them. Temperatures will warm to a high near -5 °C on Saturday as this system pushes the Arctic front back north of the region , then drop to around -10 °C on Saturday night and hover around that mark on Sunday. The region will see southeast winds up to 30 gusting 50 km/h on Saturday ease to light overnight.

While the system moving through the Prairies this weekend will bring a total of 10 to 20 cm of snow to many areas west and north of Winnipeg, the Red River Valley will likely only see 5 to 10 cm of snow by the time it tapers off later on Sunday.

This system will push the Arctic cold front back south through the region on Sunday, bringing moderate northwest winds and colder temperatures. Skies will begin to clear on Sunday night with temperatures heading back down to -20 °C.

Long Range Outlook

Colder weather will settle into the region next week with daytime highs in the -20 to -15 °C for much of the week. A bit of moderation is possible mid-week as a system crossing the northern United States may spread some cloud and light snow into the region as it passes to the south. Cold weather will likely return for the end of thew eek as well with daytime highs possibly dipping into the -20s.

Today’s seasonal daytime high in Winnipeg is -11 °C while the seasonal overnight low is -22 °C.
