Calgary’s Saturday forecast features the same weather pattern that we had on Friday. Expect a mix of sun and cloud for the morning, and by 4 p.m., the city will likely see some light, brief isolated showers. The winds will get a little gusty again later in the day, up to 50 km/h. On Sunday, the day will start out with a mix of sun and cloud. The afternoon brings a good chance of rain and thunderstorms, starting after 3 p.m.. There will be consistent, widespread rainfall Sunday night until 7 a.m. on Monday, with one to two millimetres expected.
