Severe thunderstorm watch and warnings ended

Environment Canada issued a severe thunderstorm watch for southern Ontario which includes  scattered strong thunderstorms capable of producing damaging winds and large hail, with a risk of a tornado.
The Weather Network reports “This is an alert to the potential development of severe thunderstorms with large hail, damaging winds or heavy rainfall.

Summary: Weather radar at 5:50 PM indicated a line of thunderstorms extending from Apsley to just east of Cobourg catharines moving northeast at around 90 km/h. It will affect the communities of Madoc to Napanee by 7 PM. These storms are producing fairly strong winds with local damaging gusts to 110 km/h. There have been reports of three brief tornadoes within this line from two communities southwest of Kitchener as well as Fergus. Isolated tornadoes are still possible. Brief sudden torrential downpours are also occurring with this line.

Details: A line of thunderstorms is racing across Eastern Ontario ahead of a low pressure system over Manitoulin Island. Isolated storms are also occurring around the National Capital Region ahead of the main band. The main concerns are damaging wind gusts to 110 km/h and isolated tornadoes. Large hail is also possible in far Eastern Ontario.

Earlier today: “Widely scattered thunderstorms are occurring across Southern Ontario ahead of a low pressure system over Michigan.
“New thunderstorms are developing in a general swath from Southern Georgian Bay to Central Lake Erie and will intensify as they quickly track northeastwards reaching Eastern Ontario late in the day.
“Isolated storms are also developing in Eastern Ontario ahead of the main band. The main concerns are large hail up to 3 centimetres and damaging wind gusts to 110 km/h. There will also be an increasing threat during the afternoon for an isolated tornado.
This watch may be upgraded to a tornado watch as the storms develop, if their evolution dictate a higher tornado risk. Frequent intense lightning and torrential downpours may also be expected.”
