A week or two ago, we had plenty of reports of temperatures reaching 30 in Calgary, according to thermometers in cars and backyards. Officially, though, the highest temperature so far this year at the place of record (Calgary airport), is 29.4, set on July 28. We have yet to hit 30. That is expected to happen as a monster ridge of high pressure over the southwestern United States sends heat northward. Temperatures reaching or exceeding 30 are possible Sunday, and even more likely Monday and Tuesday. Overnight lows will only reach the mid teens, so expect Heat Warnings to be issued by Environment Canada next week, likely Sunday to Tuesday. Our next chance of significant rainfall or thunderstorms doesn't happen until Wednesday.
Friday night: Partly cloudy, low 13 Saturday: Sunny, high 26 Sunday: Sunny, high 29 Monday: Mainly sunny, high 31 Tuesday: Mainly sunny, high 30 Wednesday: Increasing cloud, afternoon and evening thunderstorms, high 27
