We saw the expected unsettled weather from our previous forecast, and in fact, the two areas of low pressure ended up being much stronger and slower moving than the models predicted, resulting in a longer period of cooler temperatures. Cooler summer temperatures usually mean daytime clouds — something most regions dealt with during a good part of last week. It definitely seems like we have undergone a change in the weather pattern. The big question, though: Is this a short-term or long-term change?

Daniel Bezte looks back on October weather on the Prairies and looks ahead to see whether there’s any consensus for this winter’s weather.
This forecast period will begin with an area of low pressure developing to our southwest. This low will help to pull up some mild air into our region but increasing clouds and showers on Wednesday and Thursday will keep daytime highs in the low 20s. The low looks like it will lift off to the northeast on Friday, allowing for clearing skies as high pressure builds across the region.
This area of high pressure looks as if it will bring sunny skies and seasonable temperatures right through the long weekend. Expect daytime highs to be in the low 20s with overnight lows dropping to around 10 C with some cooler readings in some of the more cold-prone areas.
The weather models then show more unsettled weather moving in for the start of school, as an area of low pressure with a trough extending northward is forecast to move through the northern states. This system, should it develop, will bring increasing clouds, the chance of showers, and mild temperatures as southerly winds ahead of the system pull warm air into the region. Depending on the amount of clouds and showers, daytime highs could warm into the mid-20s before cooling off later in the week.
Usual temperature range for this period: Highs, 17 to 26 C; lows, 5 to 13 C.
