In Dumbarton and, more broadly, across West Dunbartonshire: The rest of the day will see mostly cloudy skies with cool conditions, with temperatures ranging from 15 to 17 degrees Celsius. There is a possibility of some light rain, with around 0.7 mm of accumulation, and a maximum probability of 40%. Winds will be light from the southwest, reaching up to 9 mph, with gusts potentially reaching 17 mph. It should remain relatively mild and unsettled into the evening, so it’s advisable to keep an umbrella handy if planning to be outdoors. Conditions are unlikely to become particularly severe, but the combination of light rain and breezy spells could make for a rather dull and damp afternoon.
