Second day of severe risk targets Manitoba, N. Ontario

Saturday, June 8th 2019, 12:55 pm - After a stormy Friday night, a second day of storm risk beckons for Manitoba and northern Ontario.

Strong thunderstorms raked across southern Manitoba on Friday evening, bringing reports of wind gusts as high as 133 km/h, extensive wind damage, and hail as big as quarters. Intense heat and humidity will deliver thunderstorms once again on Saturday, with the risk shifting slightly eastward as the system slowly meanders into northwestern Ontario. We break down what you need to know, below.

WATCH BELOW: TRACKING STORMS, ROUGH TIMING

STORM THREAT, DAY TWO

Early-morning rumbles of thunder continued for Manitoba's Interlake Region, but it's the afternoon's storms that will be the focus for severe weather on Saturday.

The high heat and humidity that fueled Friday night's strong storms remain in place ahead of the slow-moving cold front cutting through the region. This cold front will again provide the trigger for severe storms, this time with a focus south and east of Winnipeg and into northwestern Ontario.

These storm cells, which are likely to spark through the early-to-mid afternoon, will have the capacity to generate large hail (nickel-to-quarter sized), strong winds, and heavy rain.

Unlike Friday's storms, the fuel for this second round will be largely spent through the evening hours, and that means the threat diminishes quickly into Saturday night. With that said, locally heavy rain may persist as what's left of the moisture funnels north along the front. Some parts of northwestern Ontario, particularly close to the U.S. and Manitoba borders, stand to pick up 40 to 60 mm of rain before the system moves out Sunday.

AFTER THE STORMS, A TEMPERATURE PLUNGE

The cold front brought an abrupt end to Friday's steamy temperatures across southern Manitoba. Saturday afternoon's highs will be more than 10 degrees cooler for many, taking us from well above seasonal to slightly below in less than 24 hours.

This cooler trend continues into next week across northern Ontario, where flow from the Arctic will work its way back into the region.

"Temperatures are turning much colder early next week," says Weather Network meteorologist Dr. Doug Gillham. "We may even see some single-digit highs for far northern areas that will be near 30ºC this weekend."
