Last week’s forecast worked out pretty much as expected. The weak system anticipated to move through late in the weekend was a little quicker than expected and as a result, less cool air was pulled in behind the system. This gave us warmer weather over the last part of the long weekend.
This forecast period looks to be a little more active, but overall, I don’t see much in the way of significant precipitation. We start off with high pressure well in control as a large high builds over Ontario. This will place us in a dry easterly flow that should keep any storms developing to our west, well away from our region. Under the sunny skies and fairly light winds we should see daytime highs in the mid- to upper 20s, with overnight lows in the low teens — nice summer weather.

Types of tornado mimics
Not everything with spinning winds on the Canadian Prairies is a tornado. From dust devils to cold-core funnel clouds, there are a number of weather phenomenon that fit the description.
This high will slowly move farther east over the weekend, allowing a weak area of low pressure to track through northern regions. The low will drag a weak cold front through central and southern regions sometime over the weekend, with the best bet being late on Sunday or early Monday. With not a lot of moisture to work with, only a few showers and thundershowers are expected.
The following week looks to start off a little unsettled as an area of low pressure drops southeastward out of northwestern Canada. The models don’t have a good handle on how this will play out, though, so confidence in this part of the forecast is not that high. Right now it looks like the low will take a more northerly route, keeping southern and central regions sunny to partly cloudy, with highs expected to continue in the mid- to upper 20s.
Usual temperature range for this period: Highs, 20 to 30 C; lows, 8 to 15 C.
