Heddiw, Mer
A blustery and showery day. Low risk of thunder.
Low cloud and outbreaks of rain at first soon clearing. A blustery and showery day follows, and rather cloudy, although some brief brighter or sunny spells are possible in-between any showers. Showers potentially turning heavy around midday, with the odd rumble of thunder possible, but likely turning drier across most hills through the afternoon.
