Long Range Outlook

Cloudy skies return to the city on Saturday while below seasonal temperatures stay right through the weekend. Forecasts show a moderation in temperature to only slightly below seasonal values to start next week, but no significant warming trend is on the horizon.

Today’s seasonal daytime high in Winnipeg is -10°C while the seasonal overnight low is -21°C.

Snowy Weekend Ahead

A significant change in the weather is on tap for Winnipeg this weekend as temperatures return to near-seasonal values alongside plenty of cloud and light snow.

It’s a milder, cloudy weekend ahead for Winnipeg. A series of disturbances will push eastwards over the coming days, bringing unsettled conditions to southern Manitoba. Starting with today, Winnipeg will see cloudy skies with about 2 cm of light snow that will taper off later this afternoon. Temperatures will climb to a near-seasonal high of -13°C with 30 km/h southerly winds in the morning tapering off and shifting to the north. The city will likely see periods of light snow overnight as temperatures dip to a low near -20°C.

Saturday will see Winnipeg dodging a fairly substantial winter storm. A broad area of moderate to heavy snow will pass north of the city, beginning over western Manitoba and spreading across the Interlake into eastern Manitoba through the day. Snowfall totals over western Manitoba could reach 30 cm with 10 to 15 cm likely for the Interlake and areas east. The city will likely see cloudy skies and periods of light snow, but accumulations of only 2 to 4 cm.1 Temperatures will climb to a high near -15°C and winds will be out of the northeast near 20 km/h. The snow will taper off Saturday evening followed by some breaks in the cloud and a low near -20°C.

A large swath of the Prairies will see up to 30 cm of snow over the next 2 days, but Winnipeg is forecast to miss out on most of it.

Winnipeg will see mainly cloudy skies on Sunday ahead of the next system developing that will move through the region. Most forecast models show a significant Colorado Low developing Sunday into Sunday night. There’s some uncertainty as to where the main snow for this system will set up; some models push it across southern Saskatchewan into southern Manitoba while others keep it primarily south of the border with southern Manitoba just seeing a glancing blow. Ultimately, the details won’t become clear until a bit closer to the event. If it is going to snow, it’s likely that snow wouldn’t push into the region until a bit later in the day on Sunday. The city will see a high near -14°C with northeasterly winds continuing. Temperatures will head to a low near -24°C with a chance of snow on Sunday night.

Long Range Outlook

Next week will start with any remaining snow moving out of the region, followed by a prolonged stretch of below seasonal temperatures. It won’t be as cold as the last cold snap, but it does look like much of the week will see daytime highs near -20°C with overnight lows near -30°C.

Winnipeg’s seasonal daytime high is currently -11°C while the seasonal overnight low is -21°C.

  1. If this system ends up tracking a bit further south, however, Winnipeg could easily see 5 to 10 cm of snow.

Bitter Cold Gradually Eases

Winnipeg will slowly emerge from the bitter cold with a climb back towards seasonal temperatures.

Winnipeg will see yet another day in the deep freeze today. With the Arctic high still working its way across the province, the temperature will struggle to a high near -30°C in the city today. Fortunately, winds will remain light through the day, making the cold slightly more tolerable. Temperatures will dip to a low near -36°C tonight before some cloud cover begins building into the region.

Thursday will bring milder temperatures as Winnipeg climbs to a high near -25°C. Winds will be out of the southeast in the 20 to 30 km/h range, producing wind chills in the -35 to -40 range. The city will see a slight chance of flurries with little to no accumulation. Temperatures will slowly increase overnight to around -23°C by Friday morning.

Markedly warmer temepratures will spread across the southern Prairies on Friday.

A series of disturbances will track across the province on Friday. These systems will bring plenty of cloud alongside near-seasonal temperatures to the region with highs near -11°C. The first is forecast to pass through on Friday morning, followed by the second one on Friday night into Saturday morning. These systems will bring a swath of 5 to 10 cm of snow western Manitoba and the Interlake, but here in Winnipeg there will just be a chance for a bit of light snow. Winds will once again be out of the south at 20 to 30 kn/h for much of the day. Skies will remain cloudy on Friday night as temperatures dip to a low near -13°C.

Long Range Outlook

Temperatures should remain for much of the weekend with highs near -10°C and overnight lows in the minus teens. A major pattern change is possible on Sunday as a long-wave trough moves into the region. Current forecasts indicate the development of a Colorado Low that would lift northeastwards into Minnesota on Sunday night, spreading a large area of snow across the region late Sunday into Monday, followed by breezy northerly winds and falling temperatures. Early indications are that this system could produce as much as 15 to 20 cm of snow. This leaves the city with a the chance that we may be starting off the next work week with the aftermath of a notable snow storm!

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

Brutal Cold Builds Into Southern Manitoba

Winnipeg will experience life-threatening temperatures this week as brutally cold Arctic air moves into the region.

There isn’t a whole lot of setup to this story: in the wake of yesterday’s clipper system that moved through Saskatchewan, a huge surge of Arctic air will spread across the Prairies. Today will be a comparatively mild day with a high near -18°C. Skies will clear out bys late this afternoon, marking the arrival of the bitterly cold air. Temperatures will drop to a low near -35 tonight. Winds of 30 gusting 50 km/h will be in place for Winnipeg today, easing to 20 km/h overnight. That’s a stronger wind than normally seen in Winnipeg when this cold and will produce wind chill values in the -45 to -50 range.

Tuesday and Wednesday will both bring daytime highs near -30°C for Winnipeg. Winds will increase into the 30 to 40 km/h range for Tuesday afternoon, producing wind chill values in the -45 to -50 range. The winds will then gradually diminish on Tuesday night as temperatures drop to a low near -38°C. Wind chill values will likely hover in the -45 to -50 range. Wednesday night will be marginally “warmer” with a low near -35°C.

Temperatures will struggle to climb to -30°C in the Red River Valley on Tuesday.

Needless to say, when daytime highs struggle to reach even -30°C, the cold presents a real threat to those unable to get inside. Consider donating to shelters to help those who are unable to escape the elements. Ensure that your car contains a winter survival kit if you’re travelling on area highways. Having one could mean the difference between inconvenience and serious harm if you end up stranded on the side of the road somewhere for some reason.

Winnipeg may challenge some records in the coming days. While we are unlikely to set record lows unless temperatures really drop on Tuesday night and end up in the -40s, the city may see some new record low maximum temperatures. The record low maximum for January 29th is -32.0°C set in 2004. The record low maximum for January 30th is -30.8°C, also set in 2004.

Long Range Outlook

Cloud cover and milder temperatures will begin working into the city through the remainder of the week. The city should see a daytime high in the -25 to -20°C range on Thursday followed by near-seasonal values on Friday. Some snow is possible to round out the work week and start the weekend.

Winnipeg’s seasonal daytime high is currently -12°C while the seasonal overnight low is -22°C.
