Warmer, but Windier
Expect the temperature to rise after midnight Saturday morning, as a wind shift to the west brings in milder weather for the weekend. The wind will be brisk at times, gusting to 40 km/h in Calgary on Saturday. The wind will be even stronger in southern Alberta. Temperatures will climb above zero and above average for Saturday and Sunday. Then it gets complicated. The chinook breaks down Monday morning, so temperatures on Monday will drop through the day. Light snow or flurries are possible as the colder weather returns. It'll stay cold until late in the day Tuesday, when the temperature will again rise through Tuesday night and early Wednesday morning. That marks the return of milder weather, which should stay through the rest of next week.
