Things are looking not too bad for those who want to see snow or deep freeze temperatures. As we start this forecast period, a strong area of Arctic high pressure is dropping southeastwards over the eastern Prairies behind the strong area of low pressure that zipped through on Tuesday. Over the western Prairies, the weather models show a strong ridge of high pressure building over B.C. which is expected to transition eastwards.

Prairie forecast: Melting in the west, milder in the east
Forecast issued Dec. 4, covering Dec. 4 to 11, 2024
Prairie forecast: Short cold snap, then warmer
Forecast issued Nov. 27, covering Nov. 27 to Dec. 4, 2024
For this forecast period, it looks like some of the coldest air of the season is on its way to Saskatchewan while most of Alberta and Manitoba appear to miss the really cold stuff. The weather models are not showing any strong storm systems impacting the region but there a few weak systems that may bring a light shot of snow here and there.
US forecaster sees 57 per cent chance of La Niña developing between now and December
There is a 57 per cent chance of La Niña emerging from now to December, and it is expected to persist through January to March 2025, a U.S. government forecaster said on Thursday.
Prairie forecast: Mild weather returns
Forecast issued Nov. 6, covering Nov. 6 to 13, 2024
The weather models are showing an area of low pressure tracking across northern Canada on Wednesday and Thursday. This, combined with a digging trough of low pressure off the West Coast, will open the door for mild air to flood across the Prairies—first from the Pacific then from the western U.S.
Prairie forecast: Warmer weather to continue
Forecast issued Oct. 30, covering Oct. 30 to Nov. 6, 2024
For this forecast period, as we work into what's often the first month of winter across the Prairies, it looks like the current warmer and drier-than-average pattern of the last two months will continue. Now, to be fair, we need to realize that we are transitioning into winter. Average temperatures are cooling, so though the forecasting is calling for above-average temperatures, those temperatures are getting cooler and cooler.
Prairie forecast: Mild pattern trying to hold on
This forecast starts with an area of low pressure over northern Ontario and a resulting push of cool air over the eastern half of the Prairies. Over the western half of the Prairies, a weak ridge of high pressure is moving in. This will bring sunny skies and average or above average temperatures.
Prairie forecast: No snow – yet
Forecast issued Oct. 16, covering Oct. 16 to 23, 2024
As we work our way towards winter, we'll eventually have to start talking about snow... but it looks like that type of weather is at least another week away. Instead, the models show unseasonably warm weather continuing across much of the Prairies over this forecast period.
US forecaster sees 60 per cent chance of La Niña weather in September-November
There is a 60 per cent chance of La Niña weather conditions emerging in September-November and they are expected to persist through January-March 2025, a U.S. government forecaster said on Thursday.
Prairie forecast: Mild temperatures to continue
Forecast issued Oct. 9, covering Oct. 9 to 16, 2024
As this forecast period starts, the Prairies are feeling the effects of an upper ridge as it slowly slides eastwards and breaks down thanks due to low-pressure tracking over the ridge. Here is where things get interesting. Overall, the models have consistently shown an area of low-pressure tracking over the ridge late this week and over the weekend. This low is forecasted to drop southeastwards and deepen dramatically.
Warmer, drier October followed by colder, snowier November
The balance of October is likely to remain warmer than normal across the Canadian Prairies, but the weather could turn colder than normal in November, Weatherlogics chief scientist Scott Kehler explained.
