In Grenville and, more broadly, across the province of Quebec: This evening, skies will be a mix of sun and cloud across the region, with temperatures generally ranging from 14 to 20 degrees Celsius. In many areas, there is a chance of light rain or showers, with some locations experiencing up to about 1.4 mm of precipitation. Winds will be mainly from the west at around 11 km/h, with occasional gusts reaching approximately 29 km/h. While conditions are relatively calm, the potential for brief showers means there could be some localized wet spots. Temperatures are expected to gradually cool through the night, and conditions should remain fairly mild overall. Residents should be prepared for occasional light rain and gusty winds in parts of the region over the next few hours.
