In London and, more broadly, across the province of Ontario: The evening will see mainly clear skies across the region, with temperatures gradually falling to between 16 and 21 degrees Celsius. In many areas, conditions remain dry, and no significant precipitation is expected overnight. Winds are generally light from the east, with speeds reaching up to 12 km/h and gusts possibly hitting around 21 km/h. These gentle breezes are unlikely to cause any hazards, but they may bring a slight cooling effect as the night progresses. Overall, tonight is expected to be calm and mild, with comfortable conditions persisting into the early hours.
