Sizzling heat set to fizzle in B.C. with a cooler pattern looming

Heat will persist on Wednesday in B.C., alongside a thunderstorm risk, before a pattern change will bring cool and rainy weather, gradually, on Thursday

It's been an above-seasonal June across British Columbia this year, being two degrees warmer on average than usual. In fact, the last time we saw below-seasonal temperatures in the province was back on June 10 in Vancouver. However, this was quickly followed by the hottest day of the year so far on June 15, when temperatures reached 27.3°C.
