Small showers originating over Devon and Somerset slowly move eastward over Chilbolton. A low develops over North Wales and the showers appear to be developing in a northward direction whilst retaining some of their eastward movement. Mostly rainfall peaks at 2-4km, until from 2pm a few showers peak at 6km.
