The long weekend felt much longer for some as a severe thunderstorm developed south of Dryden Saturday. The storm brought a mixed bag of weather to areas east of Thunday Bay Sunday -- everything from thunderstorms to wind to showers.
On Monday, the low pressure system tracked northeast of province prompting thunderstorm watches across the board. Late afternoon, a trained spotter reported large marble sized hail in Windsor. The system will also affect parts of Quebec by late evening.
This is the same system that brought similar weather into Manitoba Friday.
Emergency Management Ontario is reminding residents to immediately take cover in the wake of any threatening weather.
