After severe storms, tornado warnings, Prairie storm risk returns

Wednesday, July 8th 2020, 8:14 pm - After a stormy Tuesday that brought damaging storms and at least one potential tornado to Alberta and Saskatchewan, the worst risk shifts eastward out of the region into northwestern Ontario, though lingering in central Saskatchewan as well.

Strong Tuesday storms brought tornado warnings to Alberta, with some storm damage reported in Saskatchewan as well. For Wednesday, the worst risk looks to be in Manitoba and northwestern Ontario, with a patch of severe potential in the latter province. Further to the west, widespread showers look set to continue Wednesday, and Alberta looks to be near or below-seasonal for the foreseeable future. Details and timing, below.

  • Widespread rain continues Wednesday, especially in Saskatchewan and Alberta, locally heavier in thunderstorms
  • Severe storm risk zones in northwestern Ontario, Saskatchewan
  • Keep an eye on weather ALERTS in your area


Though there is some chance of thunderstorms in northern Alberta Wednesday, any that do spark look to be non-severe.

The real show will be far to the east, with a widespread storm risk across Manitoba, a slice of Saskatchewan, and northwestern Ontario. Some storms will indeed be ongoing in the latter province Wednesday morning, but forecasters are eyeing another round for more severe risk, including some supercell potential, moving in from Minnesota Wednesday afternoon and evening.

The storms of the past few days have not been friendly for farmers caught in cells with isolated heavy hail, but generally, the region has seen a fair bit of precipitation, and it's not quite done yet Wednesday, as the effects of a slow-moving low continue for one more day. Presently, the heaviest amounts are expected to straddle the Saskatchewan/Manitoba border.

It should be noted that rainfall amounts will be even higher in places where thunderstorms produce locally-heavy downpours.
