Make the most of the beautiful weather this weekend! Temperatures will start to climb on Saturday. Expect fog patches early in the morning, then a sunny day with a high of 18 C in Calgary. Even brighter and even warmer on Sunday as the temperature climbs into the 20s. Monday will still be warm, but it will be mostly cloudy and the winds will start to pick up in the afternoon. By Tuesday, we start a long stretch of unstable, cooler weather. Tuesday has the potential to deliver 10 mm of rain.
