Safety and planning notes
With a measurable chance of showers and the possibility of a thunderstorm this afternoon, plan outdoor activities with flexibility. Thunderstorms can bring localized heavy rain, lightning and sudden wind gusts. If thunder is heard, follow the guideline to seek safe shelter indoors until the storm has passed.
Drivers should be aware of morning and overnight fog patches that will reduce visibility at times. The humidex in the upper 20s today means those sensitive to heat or humidity may feel uncomfortable; stay hydrated and limit strenuous activity during the warmest part of the day.
We will monitor updates to the forecast and any severe weather watches or warnings issued by Environment and Climate Change Canada. For now, expect a mostly pleasant week with typical summer temperatures and a few wet interruptions.
