A cold front is expected to sweep across Eastern Ontario this afternoon and early this evening. A warm and humid airmass over these regions will provide sufficient energy for strong thunderstorms to develop this afternoon into early this evening over these areas. Some of these thunderstorms may become severe with large hail, damaging winds, and torrential downpours. There is a lesser risk of an isolated funnel cloud or tornado.
