There definitely seems to be a shift going on in our overall weather pattern as the atmosphere begins to take on a fall-like pattern. Currently it doesn’t look as though this September will see the amazing weather that we saw last year.
By mid-week, the large area of low pressure that affected much of southern and central Manitoba over the past several days will have pushed off to our northeast, only to be replaced by a weaker area of low pressure. This low will bring a mix of sun and clouds on Wednesday and Thursday along with the occasional shower.
Fortunately, the long weekend is looking pretty good. High pressure is expected to build in on Friday, bringing with it plenty of sunshine along with high temperatures in the low 20s. This first area of high pressure will then be replaced by a second high that will drift down from the north on Sunday. While this high will keep our skies mainly clear, temperatures will cool a bit with highs struggling to reach 20.
At the same time, low pressure will be forming to our west and we should start to feel the influence of this low sometime late on Monday or early Tuesday. Temperatures will warm up a little bit on Monday, but some of that warming may be offset by clouds as the low approaches. This low looks like it will bring clouds and showers to most of southern and central regions of Manitoba on Tuesday and Wednesday. Temperatures look like they will be fairly mild in the south, with highs around 20, but further north highs will only be in the low teens.
Usual temperature range for this period: Highs:16 to 27 C Lows:5 to 13 C
