FORECAST DISCUSSION
On Thursday, a cold front is forecasted to sweep across Southern Ontario, bringing the risk of thunderstorms. During the early afternoon, a line of storms is expected to develop along the front, starting from Georgian Bay and extending southwest towards London. Throughout the afternoon and early evening, the line will track eastward.
Considering the environment, there is potential for these storms to become severe. The main threat associated with them will be damaging wind gusts exceeding 90 km/h. Although not the primary concern with this storm mode, there is also a possibility of nickel to quarter-sized hail. Additionally, an isolated tornado cannot be ruled out.
However, there is some uncertainty regarding the timing and the exact strength of the environment. Therefore, at this point, we are maintaining an 'isolated' risk. After reviewing the latest data, we may consider upgrading some areas to a 'slight' risk in our update on Wednesday evening.
