Abundant storm energy brings flood and tornado risks Thursday
Thursday brings significant weather risks to eastern Ontario, southern Quebec and northern New Brunswick, as the recent high heat and humidity are providing ample storm energy across the regions. MUST SEE: Severe storms are expected in multiple rounds Thursday afternoon and evening, and after several days of heat and humidity above 30°C, the abundant moisture in the region could result in torrential downpours. Conditions may also align for potential tornado development north of the Ottawa Valley, across the Laurentians, and in the Gaspé Peninsula. A tornado warning covered the Pembroke, Ont. area just before the lunch hour, but was discontinued shortly after. Tornado-warned storms are likely throughout the day. You'll want to stay updated on the weather alerts in your area as conditions can change quickly when severe weather hits. Thursday: Risk of strong thunderstorms with heavy downpours and a possible tornado A low pressure system and a strong cold front will move through the Great Lakes Thursday, tracking eastward through the day. These conditions will bring the potential for severe thunderstorms in several areas, particularly in eastern Ontario, southern Quebec, and parts of the Maritimes. Storms moving through the Greater Toronto Area (GTA) are expected to remain non-severe, as energy will peak further east ahead of the cold front by the afternoon. This increased energy, combined with ample moisture and notable wind shear, could fuel a strong cluster of storms. SEE ALSO: North of the Ottawa Valley, severe storms could begin in the afternoon. By evening, areas including eastern Quebec, the Gaspé Peninsula, and northern New Brunswick will also face a severe weather risk. Ottawa and Montreal residents should prepare for heightened storm intensity between 1–4 p.m., with the window extending from 1–7 p.m. for Quebec City and 3–9 p.m. for the Gaspé Peninsula and northern New Brunswick. Locally intense rainfall is possible, with 50–100 mm expected in some areas due to thunderstorms. This raises the risk of localized flooding. Conditions north of the Ottawa Valley, the Laurentians, and the Gaspé Peninsula may also support isolated tornadoes. DON'T MISS: It will be important to stay weather-aware throughout the day, and keep updated on any weather alerts or warnings issued in your area. Following Thursday's storm threat, relief from the heat is on the way, as cooler, drier air moves in for Friday. A more comfortable and seasonal weekend is ahead.

Ontario campers beware: Severe storm, tornado risk builds Saturday
Conditions favourable for severe thunderstorms will build across portions of Ontario on Saturday as a low-pressure system from northern Ontario sweeps over the Great Lakes region. Heat warnings are in place for much of southern Ontario as the hot and humid weather settles in this weekend. This instability will fuel a risk for strong to severe storms—including the risk for one or two tornadoes. Make sure you keep an eye on the radar—especially if you have outdoor plans—and stay aware of any severe weather watches or warnings issued in your area. DON'T MISS: Parts of northwestern Ontario already received a helping of thunderous weather early Saturday morning, but we'll see the risk of thunderstorms continue to shift southeast throughout the day as the low-pressure system treks across the province. Strong thunderstorms are expected to develop in the early to mid-afternoon hours and continue through the evening across northeastern Ontario, moving southeast into cottage country. A warm front and upper-level trough will increase the risk for severe storms to develop. While the storm risk extends across much of southern Ontario, the greatest risk for severe weather will fall along the shores of Lake Huron and Georgian Bay, extending north toward the Greater Sudbury Area and North Bay. There is also an isolated risk of one or two tornadoes in these areas on Saturday. The storms will form into a line and continue moving east across parts of central Ontario. Forecasters are also looking at the risk of rotating storms developing around the Parry Sound area and through a chunk of cottage country. Click here to view the video The greatest risk with Saturday's strongest storms will be hail 2+ cm in diameter, strong wind gusts of 90+ km/h, and heavy downpours that could produce 30-50 mm of rainfall. Many people are at cottages and camping in this region. Falling trees and lightning strikes are both deadly hazards. RELATED: If you are in the region, please stay on top of severe weather alerts and know what to do and where to go in the event severe weather approaches. If you know anyone in northeastern Ontario or cottage country this weekend, please ensure they're aware of Saturday's severe weather threat. A risk for thunderstorms will redevelop on Sunday as a cold front pushes into an unstable atmosphere across the Greater Toronto Area and into eastern Ontario, including Kingston and Ottawa, and into southern Quebec. We could once again see some of Sunday's storms turn severe. Click here to view the video Stay with The Weather Network for more information and updates on your weather across Ontario.
