An unsettled weekend ahead

Precipitation across Prairies as departure from average during 30 days ending Aug. 13.

The first half of last week’s forecast played out as expected, with plenty of warm weather late in the week followed by some stormy weather over the weekend. Cool weather then moved in at the start of this week. Unfortunately — or fortunately, for those who like it a little cooler — it looks like this cool weather pattern will stick around a little longer than first expected.

This forecast period will begin with a fairly strong area of low pressure tracking by to our southeast. It should be far enough to our south and east that only far-eastern areas will see a few clouds. For the rest of the region, Wednesday should have nice sunny skies, along with daytime highs in the low 20s. Temperatures will warm up a bit on Thursday and Friday as an area of low pressure develops to our west. This low is forecast to strengthen and begin pushing into our region sometime Friday. We’ll see increasing clouds on Friday with showers and thundershowers developing late in the day and continuing on Saturday as the low pushes through. There is a chance that we may see a period of steady rain on Saturday, depending on how strong this low gets.

By Sunday the low will have moved off into Ontario, but we’ll still feel its effects with fairly brisk northerly winds and a mix of sun and cloud with scattered showers. Temperatures will be on the cool side, with the high struggling to make it to 20 C.

The first half of next week looks to be pretty nice as surface high pressure builds in, bringing plenty of sunshine and warming temperatures, with highs on Tuesday and Wednesday expected to be in the mid- to upper 20s and overnight lows in the low teens.

Usual temperature range for this period: Highs, 19 to 28 C; lows, 6 to 14 C.
