The mild conditions are expected to hold steady through the start of the coming week. Monday will see sunny skies and a high of 17°C, followed by another sunny day on Tuesday with a high of 14°C. These temperatures sit above the seasonal normal for mid-April, which typically sees a daily high of 13°C.
A significant change in weather is forecast for Wednesday, as windy conditions bring a much cooler high of 7°C. The cooling trend will continue into Thursday, with temperatures dropping to a daytime high of only 4°C.

This volatility is part of a broader, colder-than-normal spring season across the province. While the weekend offers a chance for outdoor activities, the upcoming mid-week shift serves as a reminder of the rapid changes common during spring in southern Alberta.
