Forecast: Warm weather to stick around

Issued July 2, 2018: Covering the period from July 4 to 11, 2018

This map shows the total amount of precipitation that fell across the Prairies during the 30 days ending June 28. Western Manitoba, eastern Saskatchewan and northern Alberta saw near- to above-average amounts of rain. The driest area stretched from Saskatoon southwestward into southern Alberta.

After a fairly active period that brought a mix of sun and clouds along with scattered showers and thundershowers, it looks like things will settle down a bit for this forecast period.

We’ll begin this forecast period with one last area of low pressure moving across our region on Wednesday. Expect clouds and showers along with some embedded thundershowers to persist for most of the day, with clearing moving in by the evening. High pressure will then start moving in from the west on Thursday, bringing with it sunny skies and warm temperatures. This high will slowly drift eastward, ending up over the Great Lakes by Saturday. Saturday looks to be the warmest day, with daytime highs expected to be in the low 30s.

An area of low pressure is forecast to track across the northern Prairies on Saturday and this will drag a cold front across southern and central Manitoba late Saturday or early Sunday. This front, combined with the hot weather in place, will likely trigger some thunderstorms.

The first half of next week looks to be relatively quiet as a weak high pressure builds back in. Expect sunny to partly cloudy skies, with maybe the odd late-day thundershower each day. Temperatures will be near to slightly above average, with daytime highs forecast to be in the 26 to 30 C range and overnight lows in the mid-teens.

Usual temperature range for this period: Highs, 22 to 31 C; lows, 10 to 17 C.
