Forecast: Warm weather and humidity to return

Covering the period from June 24 to July 1

This weather graphic shows the total amount of precipitation that has fallen across the Prairies so far this growing season (April 1 to June 17) as percentiles. It has been very wet across central Alberta and Saskatchewan, with exceptional wetness over
a large area around Edmonton. Across much of southern Saskatchewan and Manitoba it has been dry, with a large area seeing moderately to extremely dry conditions.

After a string of weeks where the weather models did a pretty darned good job with the forecasts, last week’s forecast ended up as a bit of a stinker. Hopefully the transition to summer is finally done, which should mean a little less volatility in the weather.

For this forecast period, we will finally be saying goodbye to the pool of cool air in the upper atmosphere that brought the cool and unsettled weather to our region over the weekend and into the first part of this week. The weather models then show weak high pressure settling in across our region, bringing sunny to partly cloudy skies. Daytime highs should warm into the mid- to upper 20s from Wednesday right through to Sunday, with overnight lows falling into a comfortable 12 to 14 C range. Southern regions could see the odd shower or thundershower on any given day as a weak disturbance slowly drifts through the Dakotas.

To start next week (June 29 to July 1), the weather models show an area of low pressure developing to our southwest. The counter-clockwise flow around this low will help to pump warm, humid air into our region, with daytime highs forecast to nudge their way into the high 20s to low 30s and dew points climbing into the upper teens. With the heat, humidity and energy from the nearby low, expect to see the chance of thundershowers and thunderstorms become more widespread as the week progresses. The best chances for storms look to be late Wednesday into Thursday.

Looking a little further ahead, the weather models are leaning toward a hot start to July, with daytime highs forecast to be at or even above the usual temperature range for this time of the year.

Usual temperature range for this period: Highs: 21 to 29 C; lows, 8 to 16 C.
