Nocturnal storm risk continues overnight
Saturday saw tornado-warned storms capable of producing baseball size hail in Manitoba. These storms will continue and regenerate through the overnight hours, bringing a risk for flooding rainfall.
The greatest rainfall accumulation is expected across southeastern Saskatchewan and western Manitoba, with the heaviest totals along the shorelines of Lake Winnipeg, Cedar Lake, and Lake Winnipegosis.

The main event arrives during the day Sunday, when we’ll see ample instability, strong upper-level winds, rich moisture, and a trigger to spawn storms all line up through the afternoon and evening hours.
As a result, severe thunderstorms are likely across southern portions of Saskatchewan and Manitoba. This will be a more widespread risk than we saw on Saturday.
