Workweek Outlook: June's zonal flow may break in July

What about that wind? 

That was the question I've been asked the most since the snow has melted. 

June temperatures were almost bang on their seasonal values, and even though it felt a little damp - the Sault area only had a little more rain than normal. The big difference was the wind and the resulting rain every few days.

Winds are blowing above our heads at the midway point of our atmosphere, controlling the speed and direction of weather systems. This spring, that flow has been in what we call zonal flow from west to east.  This setup creates fast-moving weather systems that never hang around for long but brings lots of wind and rain every few days.  For us to find a long stretch of warm sunny weather, it'll mean this pattern needs to change, which is expected to happen in July.

Monday will be cloudy with rain and off throughout the day as temperatures reach 20°C.  The rain will arrive early in the morning, with a break in the afternoon before it returns for the evening.

Skies should gradually clear on Tuesday, with daytime highs reaching 23°C.

Wednesday will be mostly sunny with daytime highs near 25°C.  The end of this work week brings mostly sunny skies and temperatures in the mid to upper 20s.
