Well, the weather did not play out quite like it looked like it was going to last week, but the overall results were about the same. Last week’s cold front took longer than expected to push through (Thursday/Friday instead of Wednesday) and the area of high pressure did finally build in over the weekend bringing with it the sunshine and mild temperatures. In fact, over the first half of September we have come in nearly 7C above average and are currently the warmest month this year.
It looks like this July-like weather will continue for at least the remainder of this week and possibly into the first half of next week. A ridge of high pressure over much of Western Canada looks like it will continue to dominate. An upper-level low that has been meandering around since last weekend looks as if it will push through central regions of Manitoba on Wednesday or Thursday and this feature could trigger the odd shower or thunderstorm.
A surface high will push down from the northwest late in the week bringing some cooler air with it. Northern and eastern areas of agricultural Manitoba could see some light frost on Friday or Saturday morning. Daytime highs still look to be on the mild side under plenty of sunshine.
As the high pulls off to the southeast we will see temperatures peak out late in the weekend or early next week as our flow becomes southwesterly. High temperatures will be above the high end of the usual temperature range for this time of the year. Temperatures then look to cool down towards more seasonal values for the remainder of next week.
Usual temperature range for this period: Highs: 10 to 22C Lows: 0 to 10C
