You never know when lightning will strike.
Vancouverites who have been hoping for a cool respite in the midst of yet another toasty spell may get some thundering theatrics instead.
The Metro Vancouver weather forecast includes the possibility of thunderstorms during the tail end of a heat warning in the region.
Starting on Thursday (Aug. 18), Environment Canada calls for mainly sunshine and clear skies with a soaring daytime high of 27 C on the coast and 33 C inland. With humidity, these temperatures will feel even hotter, at 33 C and 39 C, respectively.
But some clouds are expected to roll into those humid summer skies around midnight, painting the perfect playground for stormy weather.
While the temperature isn't expected to dip below 19 C, there is 30 per cent chance of thunderstorms overnight and continuing into Friday morning.
Once the skies clear, temperatures are forecasted to climb up to 24 C on the coast and 28 C inland; they will feel more like 29 C and 33 C with humidity, however.
Clear skies and highs in the mid-20s are expected over the weekend, with overnight lows dipping down to 16 C.
Heading into next week, Monday and Tuesday are expected to see a mix of sun and clouds with highs in the mid-20s and overnight lows in the mid-teens.
