Temperatures are expected to improve in Calgary Tuesday afternoon.

It will be mostly cloudy across central and southern Alberta with a chance of non-severe thunderstorms late in the day. These thunderstorms may be isolated, but slow moving which means localized flooding could be a concern for Calgary and the southern foothills. That risk ends Tuesday evening and clouds persist overnight.

Moisture returns Wednesday afternoon as a low pressure system tracks over the Rockies and moves east into central and southern Alberta. This system could bring significant rainfall across the region before more settled weather returns Friday.

  • Cloudy, chance of late day thunderstorm
  • Daytime high: 22 C
