CALGARY -- Wind speeds across the foothills strengthen Saturday night with gusts that could exceed 100 km/h by Sunday. For Calgary, those gusts could reach 70 km/h Sunday morning before diminishing Monday.

These west winds help push temperatures further above zero, which could make Sunday the warmest of the next five days.

Wind gust forecast for Feb. 20.

The gusty conditions are associated with a low pressure system moving in from B.C. bringing heavy snow to southeastern parts of that province.

This system pushes across the Rockies late Sunday night, bringing a chance of showers across central and southern Alberta starting Monday morning, and transitioning to snow by the evening. Snowfall totals depend on when that transition takes place, but southern Alberta could get roughly 5 cm of snow by Tuesday morning.

Here’s the five day:
