FORECAST DISCUSSION
There is the risk of pop-up thunderstorms stretching from Southwestern Ontario into the Golden Horseshoe during the afternoon and early evening on Sunday. These storms should remain non-severe and relatively weak for the most part.
However, there is a chance that a few become marginally severe with up to quarter-sized hail, strong wind gusts and localized flash flooding being the main threat. The flood threat in particular could be a concern as these storms will be moving very slowly and may lead to locally significant rainfall totals in a short time frame. Additionally, there is also a questionable funnel cloud risk which in rare cases can lead to landspout tornadoes.
