Reading Time: 3 minutes This forecast period starts with the last of the bitterly cold air departing Manitoba thanks to a weak area of low pressure that moved through on Wednesday. This low, combined with an area of high pressure building over the northwestern U.S., helped to pull mild air in off the Pacific and push it eastwards across the Prairies.

Prairie forecast: Warm west, cooler east

Prairie forecast: Mild start replaced by Arctic high pressure
Forecast issued January 15, covering Jan. 15 to 22, 2025
Reading Time: 3 minutes We start this forecast period with an area of low-pressure sliding southeastwards through the southern Northwest Territories and into northern Manitoba. This low is pulling mild air northwards, which means a continuation of mild temperatures in Alberta, while Saskatchewan and Manitoba are seeing a rapid rebound from the cold start to the week.

US forecaster says La Niña conditions present, could persist through Feb-April
Reading Time: < 1 minute La Niña conditions are present and there is a 59 per cent chance of it persisting through February-April 2025, with a 60 per cent chance of transition to ENSO-neutral conditions during March-May 2025, a U.S. government forecaster said on Thursday.

Prairie forecast: Battle between warm and cold
Forecast issued January 8, covering January 8 to 15, 2025
Reading Time: 3 minutes For this forecast period, the weather models have been bouncing back and forth between a return to cold weather after a brief mid-week warmup or a return to the mild weather pattern we saw during much of December. The models have been slowly converging towards the milder solutions, but at this point confidence in the second half of this forecast period is low.

Canadian Prairies, U.S. Midwest to get colder in January as South America becomes hotter, drier

What are atmospheric rivers and why do they cause flooding?
Reading Time: 2 minutes Atmospheric rivers are storms akin to rivers in the sky that dump massive amounts of rain and can cause flooding, trigger mudslides and result in loss of life and enormous property damage.

Prairie forecast: Colder weather moving in with the New Year
Forecast issued Dec. 31, covering Dec. 31 to January 8, 2025
Reading Time: 3 minutes For this forecast period, it looks like the quiet weather pattern will continue as the weather models are not showing any big storm systems impacting the Prairies. We should continue our slow cooldown with temperatures during most of this forecast period looking to be near to below average.

Prairie forecast: Mild, quiet holidays expected
Forecast issued Dec. 24, covering Dec. 24 to Dec. 31, 2024
Reading Time: 3 minutes The weather for this forecast period will be largely controlled by a large, stationary area of low pressure in the Gulf of Alaska. This has been sending wave after wave over energy into coastal B.C. This will result in a predominately west to southwesterly flow across the Prairies—meaning a continuation of mild temperatures as Pacific air dominates.

Prairie forecast: Cold start, but then turning mild
Forecast issued Dec. 18, covering Dec. 18 to 25, 2024
Reading Time: 3 minutes To start this forecast period, we have a strong area of Arctic high pressure dropping southeastwards behind the area of low pressure that hit the eastern Prairies earlier in the week. This high will bring a quick shot of cold weather to Saskatchewan and Manitoba from Wednesday to Friday.
