Forecast: Active summer pattern developing

Issued May 28, 2018: Covering the period from May 30 to June 6, 2018

This map shows the total amount of precipitation that has fallen across the Prairies during the 14 days ending May 24. 
During this period, early-summer thundershowers and storms brought some relief to dry areas; 
parts of eastern Saskatchewan and southeastern Manitoba saw significant rainfall.

As I pointed out in last week’s forecast, some areas would see rain while other areas might miss out, and this is exactly what happened. While some regions have seen the drought conditions come to an end, other areas continue to struggle with dry conditions.

For this forecast period, it looks like we may just break out of drought conditions across all regions, as the weather models forecast a switch in the weather pattern toward a more normal June or early-summer pattern. June is typically the wettest month of the year and it looks like the first week or so of June will try to live up to its reputation.

To begin this forecast period the weather models show a broad area of low pressure working its way northeastward out of the south-central U.S. This system will likely bring more clouds than sun across our region, along with a good chance of showers and thundershowers. Temperatures will be cooler under the clouds, with daytime highs expected to be in the low 20s and overnight lows around 10 C.

There will be several areas of low pressure working their way northeastward during this forecast period, each bringing with it a mix of sun and clouds, along with the chance of rain in the form of showers or thundershowers. The exact timing of these systems is a little up in the air. The next best chance of rain is expected to be late on Friday and into Saturday morning. The weather models then show high pressure rebuilding across our region next weekend and into the early part of next week, bringing a return of sunny skies and warm temperatures.

Another area of low pressure is then forecast to move across our region around the middle of next week, bringing with it another chance of showers and thundershowers.

Usual temperature range for this period: Highs, 17 to 28 C; lows, 4 to 14 C.
