In Hamilton and, more broadly, across the province of Ontario: Across the region this evening, mainly cloudy skies are expected to persist, with temperatures remaining between 19 and 24 degrees Celsius. In many areas, there may be some rain or showers, although the likelihood is relatively low, with a maximum model probability of about 20%, and rainfall amounts are expected to be light, up to approximately 0.4 mm. Winds will generally be from the northwest at speeds around 25 km/h, with gusts possibly reaching up to 54 km/h, which could cause some breeziness in parts of the region. Conditions are unlikely to change significantly through the night, but residents should remain aware of the gusty winds, especially in exposed areas. Overall, a cool and breezy evening with occasional light showers in parts of the region.
