FORECAST DISCUSSION

On Tuesday, isolated pop-up thunderstorms are anticipated across a large portion of Southern Ontario during the afternoon and evening. While these storms are expected to be generally weak, their slow movement raises concerns about the potential of localized flooding.

Furthermore, there is a notable environment conducive to the formation of funnel clouds. In rare instances, these funnel clouds may touch down and transform into landspout tornadoes.

The highest likelihood for this occurrence is in the Golden Horseshoe and Central Ontario regions, although the extent of storm coverage in this area remains uncertain compared to Eastern Ontario, where more widespread activity is expected.
