Opportunity for severe weather on the Prairies could strike again

Another stormy week has taken hold of the Prairies after the first tornado of 2023 was confirmed for Canada in Saskatchewan last weekend, and now what could be the second.

Photos of what appeared to be a landspout tornado northeast of Stettler, Alta., surfaced on social media Wednesday afternoon after severe storms popped up. Environment and Climate Change Canada (ECCC) issued brief tornado warnings, but in that time, numerous photos were posted on Twitter.

Going forward, the storm threat will shift once again for Thursday, with the severe potential swinging farther south into Saskatchewan and extending into parts of southwestern Manitoba and northwestern Ontario. The risk includes large hail and strong winds.

The risk for thunderstorms will continue Friday and Saturday, but will be more confined to the eastern Prairies.

Analysis

Disturbances embedded in a westerly flow will continue to trigger thunderstorms. The upper-level pattern evolves by Wednesday, as the Prairies are put in an unstable, southerly flow on the backside of a strong, high-pressure ridge across northwestern Ontario.

This means there will be a daily thunderstorm risk across the region, so check back often for thunderstorm forecast updates.

Prepare

Stay alert and monitor the forecast for updates. Have a plan and a place to head indoors if the weather changes.
