Bright morning skies were forecast to give way to thunderclouds and lightning Saturday.
Canada’s national weather service called for a 60 per cent chance of showers or thunderstorms by late afternoon.
And with it, the rain brings lower temperatures with highs of 23 C dropping to 14 C overnight. Sunday’s high won’t top more than 20 C, perfect for the thousands of marathoners running Sunday.
But they should probably dress for rain.
The forecast Sunday is the same as today: 60 per cent chance of showers. The risk of a thunderstorm holds off until afternoon and evening when winds from the northeast will pick up to 20 kilometres an hour.
Lows overnight are 11 C.
We get the usual weekend spoiler for those who’ve noticed our weekends have been cloudy and raining: The sun comes out Monday morning and temperatures start inching up again. High Monday is 22 C.
