Yfory, Gwen
Becoming cloudier through the early hours with lowering cloud bringing periods of mist and hill fog. A mostly dry and cloudy morning and becoming breezier with a few showers developing. Showers becoming more frequent and heavier during the afternoon with a low chance of thunder. Drier by the evening with some sunshine and winds easing.
