Severe Weather Outlook
Discussion: There is a high potential for severe weather across Southern Ontario tomorrow. The main area that should expect severe weather is Eastern Ontario. Severe thunderstorms will develop across the Bruce Peninsula and Georgian Bay and move east throughout the day. More details on timing are below. It is important to note that likely not everyone in a risk area will see a severe thunderstorm tomorrow, however, due to the nature of the environment, we wanted to highlight the potential risk. This event has been rather difficult to forecast, due to differences between weather models. As stated, as a result of the very favourable environment, all of Southern Ontario has been included in a risk category. This is because a severe thunderstorm, or multiple severe thunderstorms, may pop-up across the region with little warning. More details on threats are below.
Once again, as the environment is very favourable for severe weather, including tornadoes, especially in Eastern Ontario, please heed any weather alerts that are issued by Environment Canada, including Severe Thunderstorm Warnings or Tornado Warnings. More details on emergency preparedness are below. Timing: Severe thunderstorms are expected to develop across the Bruce Peninsula and Georgian Bay around 10:00 AM. The thunderstorms are expected to become a cluster as they move east, throughout the Muskoka region, and continue to push across Eastern Ontario before moving into the United States by 6:00 PM. Threats: In the Moderate/Orange area, there is the potential for heavy rainfall within the thunderstorms, large hail, damaging winds up to 110 km/h, and the potential for one to two tornadoes. Frequent lightning and localized flooding are also likely in areas that receive thunderstorms. In the Elevated/Yellow area, there is the potential for heavy rainfall within the thunderstorms, large hail, damaging winds up to 90 km/h, and the potential for an isolated tornado. Frequent lightning and localized flooding are also likely in areas that receive thunderstorms.
Emergency Preparedness: Power outages are possible. Be sure to charge electronic devices ahead of severe weather. Secure all outdoor furniture. Monitor alerts issued by Environment Canada.
