Shortwave trough brings slight risk of storms to S. Ontario
Sunday, August 13, 2017, 8:05 PM - While high pressure will keep skies clear for most of southern Ontario Monday, a shortwave trough could bring thunderstorms to parts of the region.
"A shortwave trough will swing in from the west, bringing the slight risk for a shower, and a couple of thunderstorms along the eastern shores of Huron and into southwestern Ontario," says The Weather Network meteorologist Erin Wenckstern.
Meanwhile, northeastern Ontario is also under the risk for storms Monday as a cold front sinks south.
In a Saturday afternoon update, Environment Canada confirmed two significant thunderstorms produced tornadoes on Friday in southern Ontario.
The first EF-0 tornado, which moved across Essex County into Leamington at around 5:40 p.m., reportedly produced up to 130 km/h wind gusts. The second, an EF-2, moved east across the Hawkesville area at around 7:30 p.m. and reportedly produced 180 km/h winds.
The Hawkesville tornado had an estimated track of 5 km, and produced consistent lightning. The agency reports that significant damage was caused as winds knocked over farming equipment that weighed over a ton.
On Saturday evening, several severe thunderstorm warnings and watches were in effect in eastern Ontario. Environment Canada said the main threats with these was strong winds gusts and nickel sized hail.
Several photos of funnel clouds also appeared on social media, including the one below in Wheatley, Ont.
