When will the rain arrive in Montreal?<\/p>\n
A powerful weather system moving toward Qu\u00e9bec is expected to bring significant rainfall starting Tuesday morning. A special weather statement is in effect for several areas of southern Qu\u00e9bec, including Montr\u00e9al, Mont\u00e9r\u00e9gie, the Eastern Townships and Beauce.<\/p>\n

The transition toward Montr\u00e9al is expected in the morning, with the remnants of this heavy rainfall arriving in the afternoon and potentially continuing into the evening.<\/p>\n The system is part of a broader weather pattern creating a sharp contrast between Qu\u00e9bec and Ontario. While southern Ontario prepares for summer-like temperatures, Qu\u00e9bec is caught between two air masses, bringing more variable conditions.<\/p>\n As Ontario enjoys a brief return to summer, Qu\u00e9bec is set to remain much cooler. On Tuesday afternoon, temperatures in Windsor could climb to 28\u00b0C, with a humidex near 35. Montr\u00e9al, by contrast, is forecast to reach just 10\u00b0C.<\/p>\n The temperature difference highlights the contrasting weather conditions on either side of the Qu\u00e9bec\u2013Ontario border, as a warm air mass settles over southern Ontario while cooler, more changeable conditions persist in Qu\u00e9bec.<\/p>\n Could thunderstorms hit Qu\u00e9bec on Tuesday?<\/p>\n Along with heavy rain, the incoming system brings a risk of thunderstorms. Some of these thunderstorms could extend into Tuesday, however, heavy rainfall is expected to be the main weather concern for the province.<\/p>\n October has already been unusually active for thunderstorms in Qu\u00e9bec. The province typically records an average of five thunderstorm days during the month, but as of October 12, it has already experienced seven.<\/p>\n The month got off to a stormy start, with lightning and thunder waking residents across the greater Montr\u00e9al area on October 7.<\/p>\n RECOMMENDED:![\"Rain\"](\"https:\/\/www.newsbeep.com\/ca\/wp-content\/uploads\/2026\/10\/1791862459_860_image.webp\")
