It will be heating up again in Calgary this week. Tuesday will be toasty in the city. Calgary will get up to 27 C in the afternoon. It will come with a mix of sun and cloud. After 6 p.m. we get into a small risk of thunderstorms. Wednesday will be a hot, bright day as well. There is a decent chance of thunderstorms Wednesday night after 8 p.m. Thursday the thunderstorm risk comes a little earlier in the day, with a chance of those storms rolling after 3 p.m. There should be more heat returning to the city to kick off the weekend. We have had thunderstorms the last couple nights in Calgary. Leigh Muir caught this strike on camera.
