In the extreme southern portion of Northeastern Ontario, including North Bay, a strong severe risk is in place. Storms are projected to initiate here before tracking into Eastern Ontario during the early afternoon hours. A slight severe risk also extends into Sudbury and along the Georgian Bay shoreline, where a line of storms may form before traversing over Lake Huron. Both of these areas carry a favourable environment for large hail, strong wind gusts, and the possibility of an isolated tornado.
