This Sunday, Quebec is bracing for another tumultuous day as severe weather continues to unfold across the province. Following a weekend marked by intense instability, the forecast predicts that the unsettled conditions will persist. Over the past few days, Toronto has already experienced record-breaking rainfall, with Pearson Airport receiving an unprecedented 128.3 mm on Saturday. The violent weather even triggered a tornado near Kitchener, further underscoring the severity of the storms.
As we move into Sunday, the instability that has characterized the weekend will continue its course. The afternoon is expected to bring significant energy to the region, setting the stage for potentially electrifying thunderstorms later in the day and into the evening. Areas such as Outaouais, Laurentians, Pontiac, Vérendrye, Témiscamingue, and Montérégie should be on high alert for severe thunderstorm warnings. These storms could bring intense gusts, heavy rain, and possibly large hailstones, measuring 3 cm or more in diameter. There is even a slight risk of supercells or rotating storms, particularly in the western part of Montérégie, though this risk is considered low.
For those hoping the torrential rains were a thing of the past, it seems patience will be required. Sunday's forecast indicates that large amounts of moisture will be available in the atmosphere, with some areas along the river potentially receiving up to 40 mm of rain in a short period under intense storms. Normally, such rainfall wouldn’t be too problematic, but recent heavy downpours have left the ground saturated, increasing the likelihood of flooding and landslides.
In Montreal and other regions, the rain is expected to persist through Sunday and into Monday. According to Environment Canada, the province will see between 20 and 60 mm of precipitation depending on the area. The southern parts of Quebec will likely experience the heaviest rainfall, with potential totals exceeding 40 mm due to afternoon and evening thunderstorms. In Outaouais, additional rainfall of 20 to 40 mm is anticipated, leading to more significant accumulations compared to other regions. Meanwhile, Quebec City will see lighter showers starting around midday, with thunderstorms expected to hit overnight into Monday.
In summary, Sunday’s weather in Quebec will be anything but calm, as heavy rains, strong winds, and the risk of severe storms continue to affect the region. Stay alert and prepared for potential disruptions as these weather patterns unfold.
