Last week’s forecast played out pretty much as expected, with a couple of small but significant differences. The area of low pressure that affected southern and central regions on Thursday and Friday ended up being stronger than anticipated. This allowed for more cold air to work in behind the system, bringing fairly widespread frosts on Sunday and Monday morning. When we look at the medium-range models, this looks like it will be the last frost of the season.
For this forecast period it looks like we’ll see more sun than clouds, with only a few small chances for any rain. Temperatures look to be seasonable, with highs on most days expected to be right around 20 C, with overnight lows around the 8 C mark. The best chance for any precipitation looks to be over the weekend, as a trough of low pressure moves across Manitoba. It doesn’t look like the whole weekend will be cloudy with showers, but rather a mix of sun and clouds with a few scattered showers or thundershowers thrown in.
For next week it looks like it will be a little warmer, as low pressure begins to develop to our west. This low will start to pull warmer and more humid air up into our region, with highs by next Wednesday expected to be in the mid-20s. Unfortunately, that low will eventually track across our region, bringing with it more rain. Looking further ahead, the weather models show highs remaining in the mid-20s right through to the middle of the month.
Usual temperature range for this period: Highs, 18 to 28 C; lows, 5 to 14 C.
