Large hail and winds: Multi-day severe storm risk builds over Alberta
Active weather is set to return across central Alberta, bringing the risk of severe storms. The forecast includes a marginal potential for tornadoes in the region
Alberta faces a multi-day severe thunderstorm threat, with more impactful storms expected Wednesday. A low pressure system moving through the province will provide the necessary trigger to initiate severe weather.
Residents across impacted regions should monitor alerts, and be prepared for the quickly changing and deteriorating conditions.

Severe thunderstorm risk expands across Alberta and Saskatchewan Wednesday
The same slow-moving low pressure system that brought tornado watches and warnings on Tuesday will develop a trough by Wednesday, setting the stage for several pockets of severe thunderstorms across Alberta and extending into Saskatchewan.
Severe storms are expected along the QE2 corridor north of Calgary, tracking northeast throughout the day. At the same time, multiple clusters of thunderstorms are forecast to develop across northern Alberta, bringing localized threats.

By late afternoon, severe thunderstorms will intensify across southern Alberta and Saskatchewan. These storms are expected to persist through the evening and into the overnight hours, with storm clusters forming a line as they track eastward across the Alberta-Saskatchewan border.
Favourable atmospheric conditions include elevated thunderstorm energy and strong upper-level winds, increasing the risk of large hail, damaging wind gusts, and the potential for an isolated tornado.
Residents are encouraged to monitor alerts and have safety plans in place for changing weather conditions.
