Alberta's temperatures continue below-seasonal, with daytime highs mostly in the upper teens through the rest of the week. Even the south, while remaining warmer than the rest of the province, will be down from its early-week peak.

Elsewhere, the region looks about seasonal, with the exception of southeastern Manitoba, where "feels like" values will still be well in the 20s by the end of the week following a mid-week surge of warmth.

As for the storms, the majority of south-western Alberta and parts of eastern British Columbia could see action. Severe-storms could occur for areas around Alberta's foothills. Severe-storm risks could include large hail and strong wind gusts. Some of the storms could rotate which leads to a small tornado threat as well.

Alberta risk

Beyond, Wednesday sees storm risk shift eastward, to southern Manitoba and Saskatchewan, and further into Manitoba on Thursday, with some potential for unsettled conditions on Friday as well.

Temperature-wise, the weekend sees cooler conditions for Saskatchewan and Manitoba, but Alberta looks in line for a brief warmup.
