Seasonably Mild Temperatures On The Way!

Winnipeg will see very pleasant December weather this week as mild air floods across the region.

Winnipeg will see temperatures climb well above seasonal values as mild air floods eastwards across the Prairies. Today will bring the most sunshine of the next few to the city with nary a cloud in the sky. Temperatures will climb to a high near -6°C with light winds. The city will see increasing cloudiness tonight with temperatures dipping to a low near -11°C.

Tuesday will bring mainly cloudy skies to the city with a high once again near -6°C. Winds will be out of the south at 10 to 20 km/h. A weak upper trough moving through on Tuesday evening will bring a chance for a bit of light snow and usher in slightly milder temperatures. Under mostly cloudy skies Winnipeg will head to a low near -8°C on Tuesday night.

Wednesday will bring more cloud cover to the city, but temperatures will climb to a seasonally balmy -3°C. Winds will be out of the south at 15 to 25 km/h. A stronger trough of low pressure moving through on Wednesday evening will bring another chance for some light snow to the region as temperatures remain steady near -3°C.

Long Range Outlook

The remainder of the week continues to see very mild conditions remain over southern Manitoba. Daytime highs will climb towards 0°C by the end of the week with variable cloudiness through the second half. No major snowfall events are on the horizon.

Winnipeg’s seasonal daytime high is currently -9°C while the seasonal overnight low is -19°C.

Temperatures Return Closer to Seasonal For The Weekend

Winnipeg will see pleasant conditions this weekend with seasonably cool temperatures and variable cloud cover.

The cold weather that moved into the region yesterday has already left with a more seasonal air mass taking its place. A warm front moving into the region brought cloud through the night that will clear out early this morning. Left behind will be sunshine, light southwesterly winds, and daytime highs near -12°C. Skies will remain clear tonight with light winds as temperatures dip to a low near -18°C.

More sunshine is on tap for Saturday with a southerly flow developing ahead of yet warmer air trying to push into the region. Temperatures will climb to a high near -10°C with southerly winds near 20 km/h. Skies will cloud over on Saturday night as temperatures dip to a low near -16°C.

Sunday will bring cloudy skies to Winnipeg as a weak upper trough moves through. The city might see a few light flurries, but there won’t be any accumulating snowfall. Temperatures will be a bit cooler with a high back near -10°C. Winds will be light. The cloud cover should stick around on Sunday night with a low near -15°C.

Long Range Outlook

After the upper trough moves through on Friday, warmer air will continue to spread eastwards across the Prairies. With variable cloudiness, next wee should bring high temperatures generally around -5°C with lows near -10°C. Some days may be cloudier than others, but no major snowfall events are forecast right now. All things considered, it’s quite a pleasant start to December!

Winnipeg’s seasonal daytime high is currently -8°C while the seasonal overnight low is -18°C.

Cold Snap Comes With Quick Recovery

Winnipeg will see temperatures plummet well below seasonal for Thursday, but the cold conditions won’t last long.

An advancing cold front will bring cloudy skies with periods of light snow to Winnipeg today. Accumulations will be minimal but don’t let that fool you: this system will pack a punch. Temperatures will reach a high near -9°C this morning, but midday the cold front will slide through and shift the winds northwesterly. Winds will strengthen through the afternoon to around 30 gusting 50 km/h, ushering in a markedly colder air mass. Temperatures will fall to around -11°C by the evening, and then continue to a low near -25 or -26°C. While this is unseasonably cold, it won’t be anywhere near the record low which sits in the -30s. Skies will clear out in the evening alongside diminishing winds.

Fortunately, the cold will be short-lived. Thursday will see a daytime high colder than the seasonal overnight low as temperatures climb back to around -17°C. Winds will remain light and gradually shift to southerly as an Arctic high passes through the region into the Dakotas. The core of the cold air will already be to our east by Thursday night, with warmer air quickly moving in behind it. As a result, the city will see some cloudiness on Thursday night with temperatures remaining fairly steady near -17 or -18°C.

This forecast of temperature departures from seasonal show the core of the coldest air over southern Manitoba midday Thursday. Note, however, the flood of warmer temperatures quickly spreading back into the Northern Prairies in its wake.

Friday will bring more sunshine as temperatures continue to climb back towards seasonal. Winnipeg will see a high near -11°C with light southerly winds continuing. Temperatures will dip to a low near -15°C on Friday night with a few clouds.

Long Range Outlook

The city should see near-seasonal temperatures through the weekend with a fair amount of sunshine. Seasonal to above-seasonal temperatures look likely to start next week, but cloud and the chance for more flurries or light snow may return midweek into the weekend.

Winnipeg’s seasonal daytime high is currently -8°C while the seasonal overnight low is -17°C.

More of The Same Until Mid-Week Cold Blast

Mostly cloudy conditions will persist in Winnipeg until an Arctic cold front surges southwards mid-week and brings clearing skies along with a blast of cold weather.

Winnipeg will see near-seasonal temperatures today and tomorrow as the region remains in a relatively stagnant pattern. The vast expanse of stratus cloud that has been in place over the past several days remains. A few patches of clearing may develop through the day, but it’s practically impossible to predict where exactly that will occur before it happens. While skies should remain mainly cloudy today and tomorrow, a peek of sun is possible. Daytime highs both today and Tuesday will be a near-seasonal -7 or -8°C. Cloud cover in the region will keep overnight lows slightly warmer in the -10 to -12°C range or so.

A major pattern shift will take place on Wednesday as an Arctic cold front plows southwards though the province. The city will see cloudy skies and 2 to 4 cm of light snow as the front moves through. Northerly winds of 30 gusting 50 km/h will move in behind the front as skies clear, ushering in a markedly colder air mass. Temperatures will plummet Wednesday night to a low near -24°C with wind chill values dipping towards the mid-minus 30s.

Long Range Outlook

The remainder of the work week will bring seasonably cold temperatures with daytime highs in the minus teens.

This forecast map of temperature anomalies for Thursday shows the wide swath of temperatures well below seasonal values across the southern Prairies.

The coldest temperatures will be short-lived, though, with signs that temperatures will moderate through the weekend back towards seasonal values to start next week. On the bright side, the colder air mass will likely mean the city finally sees some consistent sunshine!

Winnipeg’s seasonal daytime high is currently -7°C while the seasonal overnight low is -16°C.
