A biting cold snap continues across much of Alberta, with sub-zero temperatures lingering—but there’s light at the end of the frost-filled tunnel.

Environment and Climate Change Canada has extended extreme cold warnings, noting that wind chill values near –40 °C remain a risk to health, particularly in vulnerable communities. Forecasts suggest that this deep freeze will persist into midweek, driven by Arctic air entrenched over the province.

Calgarians should continue wrapping up well—exposed skin can develop frostbite within minutes in such conditions, and overnight lows are still plunging deep.

The good news? Temperatures will begin a gradual climb by midweek, offering a modest reprieve. The shift is likely influenced by warming Chinook winds—a signature Alberta phenomenon known to deliver dramatic temperature swings within hours by descending from the Rockies.

Still, the transition may be unpredictable, with alternating periods of frigid and mild air. This seesaw effect is typical of winter in southern Alberta, and residents are reminded that even brief milder stretches can be misleading before the cold returns.
