Get ready for a day of summer, Calgary. Tuesday will come with all sunshine and a high of 23 C. Be sure to slap on that sunscreen, because the UV index will be high. We will get some much-needed rain this week, with two to four millimetres likely late Wednesday through Thursday morning. There’s another 10 to 20 millimetres possible Friday night through Saturday. The daytime high will slip down to 7 C on Saturday — not ideal if you’re camping. Overnight lows Friday and Saturday will also be close to that freezing mark, but we will recover into the double-digit highs by Sunday.
