Forecast: Warm summer weather moves back in

Issued June 4, 2018: Covering the period from June 6 to 13, 2018

This map shows the total amount of precipitation that fell across the Prairies this spring (March through May) as a percentage of the long-term average. Nearly all of Manitoba and Alberta saw below-average amounts of precipitation this spring, with only a few locations in Saskatchewan reporting near-average amounts.

The early part of last week’s forecast played out pretty close to what the weather models predicted, but the second half kind of fell apart as a strong upper low took control of the weather over the weekend, bringing clouds, rain and cool temperatures. High pressure did build back in to begin the week, which brought a return of sunny skies along with mild temperatures.

This forecast period will start with a weak area of low pressure exiting our region. We should see mainly sunny skies on Wednesday and Thursday along with daytime highs in the mid-20s. Southern regions might see a few clouds along with the chance of thundershowers late Thursday or early Friday as an area of low pressure tracks by well to our south.

Over the weekend it looks like we’ll see a building ridge of high pressure as an area of low pressure deepens to our west. This ridge will bring plenty of clear skies along with warm temperatures. Expect daytime highs in the upper 20s to low 30s, with overnight lows in the mid-teens. The western low is forecast to track by well to our north, but it will drag a cold front through our region sometime late Sunday or during the day on Monday. If the front moves through late in the day on Sunday or Monday, we could see some severe thunderstorms; otherwise, expect some clouds along with scattered showers and thundershowers.

Currently, it looks like we’ll only see a slight cool-down behind the front, with daytime highs forecasted to be in the mid-20s under plenty of sunshine. Looking further ahead, the weather models point toward warm and wetter conditions for the later part of next week and into the following week, as the overall flow across our region becomes more southwesterly.

Usual temperature range for this period: Highs, 19 to 28 C; lows, 6 to 15 C.
