It will get a little hotter each day in Calgary. Thursday will come with a high of 28 C, air quality at the moderate level and lots of sunshine. Saturday will be the hottest of the week with a high of 33 C. The weather pattern will shift on Sunday, which will dramatically adjust our temperatures. The daytime high on Sunday will be at least 10 degrees cooler than Saturday, and the day also brings the risk of thunderstorms.
