Scattered showers with embedded thunderstorms are possible north of Georgian Bay including Manitoulin Island, Sault Ste. Marie and Elliot Lake during the morning on Friday. These storms will be quite weak with heavy rainfall and occasional lightning strikes being the main risks. Two rounds of storms could affect far Northwestern Ontario both in the morning and during the evening on Friday as storms track into the province from Manitoba. Small hail, strong wind gusts, heavy rainfall and frequent lightning strikes are all possible with these storms usually in the evening when they are expected to be stronger.
