Despite a fairly unsettled pattern over the last forecast period, the weather models did a pretty good job of the forecast. For this forecast period, things should settle down a bit with a ridge of high pressure starting off our forecast. That doesn't mean that we won’t see any areas of low pressure, but unsurprisingly, the weather pattern is slowly shifting towards more of a fall pattern. That means quicker moving systems.

This forecast period starts with one of the northwestern U.S. lows slowly lifting northwards. The unsettled weather that started the week across parts of Saskatchewan and much of southern Manitoba looks to continue. It appears the low will only move out late Friday or early Saturday. Even parts of southern Alberta my see some rainfall from this low on Wednesday.

Our weather pattern looks to be on the brink of a shift as a trough of low pressure begins to develop along the West  Coast. For those of you in Alberta, this will mean cooler and wetter conditions. In Manitoba, it looks like summer will continue for at least one more week. If you are in Saskatchewan, well, you will be stuck in the middle of these two features.

Last week's forecast got off to a rough start. The area of low pressure that pushed through the eastern Prairies ended up as a large upper level low. Because those are slow to move out, they can affect systems trying to move east by backing them up or forcing them to take a different path. So, while the overall pressure pattern across the Prairies was still slack as forecasted, the details got all messed up.
