So far this month Mother Nature has been leaning towards providing us with warm weather, even when the weather models are trying to bring in cooler weather. The question is, will she be able to pull it off one more time or will we finally get a taste of fall before the end of the month?
For the first half of this forecast period, it looks like our summer-like weather will continue. A low-pressure system in the upper atmosphere is going to park itself over the central U. S. and a ridge of high pressure will rebuild itself across Western Canada. This ridge will bring plenty of sunshine and warm temperatures right through until Saturday. While it currently doesn’t look like we will see any record or near-record-breaking temperatures, we will have highs that are well above the usual temperature range for this time of the year.

Will Manitoba’s warm fall linger?
Weather data confirms a mild start to autumn, but forecasts farther into fall 2025 are mixed for Manitoba.
Over the weekend, the upper low over the central U. S. is forecast to push northeastward. This will bring increasing clouds for Sunday along with cooler temperatures. At the same time a strong area of low pressure is forecasted to push across the northern Prairies. These two features will help to break down the ridge of high pressure. Behind the northern low it looks like we will see a fairly strong push of cold air beginning on Monday or Tuesday of next week.
Highs for next week will likely only be in the low teens with lows falling into the low single digits. Depending on the cloud cover there is a good chance we will see our first killing frost of the year sometime between Tuesday and Thursday night.
Usual temperature range for this period: Highs: 9 to 21C Lows: -2 to 7 C
Probability of precipitation falling as snow: 10 per cent
