This map shows the total amount of precipitation that fell during the 30 days ending May 26. It’s been a fairly wet period for much of Alberta and southern Saskatchewan, with some areas reporting amounts of 75 to over 100 mm. In contrast, north-central Saskatchewan has been dry, with less than 25 mm reported. Across Manitoba, amounts are a little more consistent, varying from 25 mm over western regions to around 50 mm in east-central regions.

We ended up seeing more clouds than sun during the last forecast period, thanks mostly to a couple of upper-level lows that took their sweet time moving out of our region. All of the extra clouds and showers also helped to keep temperatures cooler than expected, with daytime highs only making it into the upper teens to around 20 C and days that stayed mostly cloudy.

This forecast period begins with another strong area of low pressure bringing more clouds and precipitation. The majority of the rain from this system should have fallen earlier in the week, with only some wrap-around showers on Wednesday. Western regions should clear out during the day on Wednesday, with eastern regions clearing later in the day Wednesday or early on Thursday.

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.

Thursday looks to be sunny and pleasant, with daytime highs expected in the low 20s. On Friday, a weak trough of low pressure will bring a mix of sun and clouds along with a chance of a few showers or an afternoon thundershower. Temperatures will be a little milder, with highs nearing the 25 C mark.

Over the weekend and into the first half of next week, the weather models show a building ridge of high pressure to our west. This ridge will slowly migrate eastward, bringing us plenty of sunshine along with warm early-summer temperatures. We should expect to see daytime highs continue to warm into the mid- to upper 20s by Sunday, with overnight lows in the 10 to 14 C range.

Usual temperature range for this period: Highs, 17 to 28 C; lows, 5 to 14 C.
