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.

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.
