A Break From The Deep Freeze

A stretch of mild weather will develop in Winnipeg this week with temperatures even climbing back towards 0°C on the weekend.

Today will mark the start of a large-scale pattern change that will cut off the supply of Arctic air to the Prairies. A westerly to southwesterly flow aloft will develop through the rest of the week, pushing warmer Pacific air gradually eastwards. Before the city sees the warmer temperatures, though, the colder air needs to vacate. Today will be the day for that; it will be a rather typical “transition day” for Winnipeg.

Moderate southerly winds of 30 to 40 km/h will persist through the day under mostly cloudy skies. There will be a slight chance of flurries this morning, but snow will likely stay mainly north of the city. Temperatures will climb to a high near -13°C.

Temperatures in Winnipeg will head to a low near -15°C tonight with diminishing winds under partly cloudy skies.

Moderate southerly winds will be in place over south-central Manitoba on Wednesday.

Thursday will bring mostly cloudy skies to the city again with a high near -10°C. Winds will be light out of the north-northeast. Temperatures will dip to a low near -13°C on Thursday night under cloudy skies with a chance of flurries.

A warm front will approach the province on Friday, keeping things cloudy with a chance for some light snow. Temperatures will continue to warm with a high near -8°C in Winnipeg. The winds will stay light, but shift to southerly.

The warm front and its parent low will push across the province on Friday night into Saturday. This will bring southerly winds of 20 to 30 km/h to Winnipeg for the night with a low near -12°C.

Long Range Outlook

Pacific air will wash over southern Manitoba on Saturday, bringing seasonably mild warmth to the region. Temperatures will climb to around 0°C this weekend with overnight lows in the -5 to -10°C range. Plenty of cloud will stick around, but by the weekend some sunny breaks look likely as well. Temperatures will cool slightly to start the new work week with daytime highs dropping into the -5 to -10°C range with overnight lows dipping into the minus teens.

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

Temperature Roller Coaster Ahead for Winnipeg

Winnipeg will see temperatures vary significantly over the next few days as Pacific lows and Arctic highs quickly move through.

The first of 3 weather systems set to impact the region in as many days is on the way. A low pressure system will move across the province today, spread warmer air across southern Manitoba. Temperatures in Winnipeg will climb to a high near -10°C with southerly winds near 20 km/h shifting to westerly late in the day. Skies will start off clear, but cloud cover will work into the region this afternoon and bring a chance of flurries with it.

Skies will clear tonight as a cold front pushes through the region. Temperatures will dip to a low near -26°C.

The second system to impact the region – an Arctic high – will move through the province on Tuesday. It will bring mainly sunny skies to Winnipeg but temperatures will be cold with a high of just -22°C. Some cloud cover will begin working in from the west on Tuesday night, but not before temperatures dip to a low near -27°C.

RDPS 2m Temperature Forecast valid 09Z Tuesday December 17, 2019
An Arctic high will move through northern Saskatchewan Monday night and into Manitoba on Tuesday. It will bring seasonably cold conditions to the region.

On Wednesday, the third system of the week will move into the province. A low pressure system will approach from the northwest, drawing another push of milder Pacific air eastwards. In Winnipeg, skies will stay mostly cloudy with moderate southeasterly winds near 30 gusting 50 km/h. There will be a chance of flurries, but the dry southerly winds will limit the potential. With warmer air pushing in, Winnipeg will see a high near -15°C late in the day. Winds will ease on Wednesday night with temperatures remaining steady near -15°C.

Long Range Outlook

The rest of the week looks seasonably mild with daytime highs climbing into the -7 to -10°C range and overnight lows in the warmer half of the minus teens. Cloud looks to be plentiful, though, and there will be the occasional chance of flurries. No significant snowfall is in the forecast.
