Record-Breaking Cold Front to Impact Ontario

Ontario is bracing for a significant cold front that could result in record-breaking weather conditions. A potent low pressure system is forecasted to sweep across the region, bringing heavy rain, strong winds, and potential thunderstorms.
Severe Weather Forecasted for Ontario
The upcoming storm, predicted to develop over the Great Lakes, poses the possibility of a record-setting low pressure that could drop to 990 mb or lower. This atmospheric condition might establish a new benchmark for the lowest June pressure ever recorded in the province.
Rainfall and Wind Expectations
- Most areas are projected to receive between 20-40 mm of rain by Thursday.
- Certain localized regions may exceed 50 mm.
- The storm’s swift motion is expected to limit extreme rainfall totals.
Despite being a summer system, the intensity and characteristics of this storm are more aligned with typical fall weather patterns. Residents should prepare for potentially severe thunderstorms, particularly on Tuesday.
Thunderstorm Alerts on Tuesday
Northeastern Ontario will see showers and thunderstorms as a warm front moves through the area. Isolated severe storms could pose risks, including:
- Strong winds.
- Hail measurements exceeding 2 cm.
- Heavy rainfall likely.
Throughout Tuesday afternoon, pop-up showers are anticipated in southern Ontario, especially inland areas. As the evening progresses, storms will expand into southwestern Ontario and along the shores of Lake Huron, moving towards the Greater Toronto Area (GTA) overnight.
Particularly strong storms near southern Georgian Bay and Lake Huron may lead to hazardous conditions, featuring heavy rainfall and gusty winds. All residents are urged to stay informed and take appropriate precautions in anticipation of this significant weather event.
