CALGARY -- Temperatures for much of Alberta are expected to soar into the 30s Monday afternoon.

Records may even be broken in extreme southern regions of the province, particularly towards the southeastern corner as temperatures near Medicine Hat will approach the high 30s.

The building heat contributes to instability across the province that supports severe storm development along the foothills and into central Alberta.
