FORECAST DISCUSSION

Widespread pop-up thunderstorm activity is expected across Southern Ontario on Saturday. Based on the latest data, there is a questionable isolated severe risk associated with these storms, particularly in Central Ontario and the Orangeville, Kitchener/Waterloo, and Woodstock regions.

Most of the storms are anticipated to occur during the afternoon, although some activity may also occur in the morning. The primary severe risk will be during the afternoon storms, which could bring threats including quarter-sized hail, wind gusts reaching 90 km/h, and heavy rainfall.

Additionally, there is a very questionable potential for funnel clouds with these storms, which in rare cases could touch down and become landspout tornadoes.
