It looks like we’ll be stuck in a rather unsettled weather pattern for at least another week, but there are some hints of some kind of change coming later next week.
This forecast period will begin with warm high pressure to our north — that’s right, to our north — and a broad area of low pressure over much of Western Canada and the northern states. There will be a bit of a pushing match between the northern high and the western low for the first part of this forecast period, with southern and central Manitoba being caught right in the middle. On Wednesday and Thursday it looks like the northern high might win out, bringing sunny skies to eastern and central regions with partly cloudy to cloudy skies the further west you go. Temperatures under the strong mid-summer sunshine should be in the 25 C range — a little cooler where there are more clouds.
It looks like an area of low pressure will cross the northern states on Friday, bringing increasing clouds along with the chance of showers or thundershowers. This low looks as if it will move quickly off to the east, allowing the northern high to slide a little southward and eastward. This should bring mostly sunny and dry conditions over the weekend, with seasonable temperatures.
Next week is when things start to get interesting. The weather models show another area of low pressure developing over eastern Alberta early in the week. This low, like several we’ve seen over the last month, is then forecast to deepen as it begins to move east. This time, thanks to the northern high sliding a little further to the southeast, the low is forecast to be pushed into the northern Prairies. We could see some clouds and showers from this low on Monday and Tuesday, but just how much depends on how far east the low tracks before it is pushed to the north. The big question to watch out for is, what kind of impact will this system have on the overall weather pattern going forward?
Usual temperature range for this period: Highs, 22 to 31 C; lows: 10 to 17 C.
