That meets the criteria for Environment and Climate Change Canada to issue a heat warning for virtually all of Alberta.

The mountain parks are not included and neither are the Lethbridge/Medicine Hat regions, which have a higher threshold for Heat Warnings.

A cold front will set off some late-day showers and thunderstorms on Thursday and usher in a bit of a cooldown for Friday and Saturday with daytime highs back in the low to mid 20s for the end of the week in Edmonton.
