While the weather across our region was relatively quiet last week, the weather pattern as a whole was not behaving quite like I predicted it would. Last week I pointed out that we were now into a summer pattern with weaker weather systems and more thunderstorms. We definitely saw more thunderstorms last week, along with hail and even the odd funnel cloud, including a weak tornado or two. Move a little farther west (Saskatchewan) and it experienced, for the first time this year, a very strong area of low pressure that brought several days of showers, thundershowers, and just plain rain.
What was summer-like with this system is that it formed much farther north and as it pushed southeastwards across our region last Sunday it weakened substantially, bringing only scattered clouds and a few showers.
For this forecast period it looks to be much of the same. A ridge of high pressure will be in place for the middle of the week, bringing sunny skies with highs in the mid- to upper 20s. Towards the weekend the weather models are having a tough time figuring out just what will happen. Currently, it looks like the ridge of high pressure will begin to collapse and move eastward as an area of low pressure develops to our west. This will bring increasing humidity into our region by Thursday, along with warm temperatures. Friday may be warm and humid as well, depending on the amount of sunshine.
Over the weekend the ridge will totally collapse allowing the western low to zip through. This will bring a mix of sun and clouds with maybe a few showers, along with high temperatures in the low 20s. Next week should start off sunny with seasonable temperatures and then transition into warmer and more humid conditions as the week progresses.
Usual temperature range for this period:
Highs: 20 to 29 C
Lows: 8 to 16 C
