FORECAST DISCUSSION
Friday afternoon and evening will feature a risk of severe thunderstorms extending from Southwestern Ontario to areas around Georgian Bay. Current model guidance suggests the potential development of a line of storms within this risk zone. These storms are likely to be severe, with the primary risks being strong wind gusts and sizable hail. While there is also a tornado risk, it remains uncertain due to the storm mode.
There is a possibility of upgrading the risk level to slight or even strong on Thursday as we gain more confidence in the exact location of the strongest storms. However, models currently disagree on the area of storm development. Therefore, we are maintaining a more widespread isolated risk until we can better determine the specific threat.
