A risk for thunderstorms will redevelop on Sunday as a cold front pushes into an unstable atmosphere across southern Ontario. The storms will develop inland and track through the Greater Toronto Area and into eastern Ontario. Some of Sunday’s storms could turn severe.

Environment Canada's tornado warning for eastern Ontario has ended. From about 3:20 until 4 p.m. the agency said a severe thunderstorm could possibly produce a tornado in communities such as Kemptville and Merrickville. It's not yet known if a tornado formed.
