After some strong overnight Prairie storms, Wednesday's storm risk straddles the Manitoba/Ontario border, where they have already begun to pop up. Environment Canada issued severe thunderstorm warnings in parts of both regions Wednesday afternoon. There has been reports of localized flooding with the storms in Manitoba. Perhaps more welcome will be a system that will cross into the region Thursday through Friday, bringing some prolonged and heavy rains that will go a long way to denting the Prairies' longstanding moisture deficit. A closer look, below.

WEDNESDAY: SEVERE STORM DRIFTS EASTWARD

Wednesday's severe threat risk shifts to the east, centred in southern Manitoba and in northwestern Ontario.

Severe storms have begun firing up in southeastern Manitoba and northwestern Ontario, where there are warnings in place. They bring the potential for strong wind gusts, heavy rain and nickel- to ping pong ball-sized hail. The threat may continue into the overnight hours for the aforementioned province, as well as in northwestern Ontario.

There has been multiple reports of localized flooding in parts of Manitoba.

The rest of the region isn't quite storm-free. Forecasters are looking at some isolated risk in Alberta and Saskatchewan Wednesday, with some slight severe potential straddling the border between the two provinces.

LATE WEEK: DROUGHT-BUSTING RAINS EN ROUTE

With a deep trough lingering on the West Coast, another system will likely develop on Wednesday in Montana, which will slowly track into the Prairies through Thursday and Friday.

This will bring more thunderstorm threats, but the bigger story will be the abundant, heavy rain this slow moving system will bring, lasting into the weekend for some places.

Most of the Prairie region is in for at least a few showers, but the heaviest rains, which are anticipated to be in Saskatchewan, could bring more than 75 mm over that time period.

Though not everyone will get as much rain as they need, this soggy set-up will be a positive story for agriculture for much of the region. It will also help to reduce the threat for wildfires.

"June is typically the wettest month of the year, and it looks like this week will deliver some meaningful relief from the drought condition," says Dr. Doug Gillham, a meteorologist at The Weather Network, adding that a drier and hotter pattern is expected to return for southern areas next week.
