Overnight we hold onto a few showers, mainly around the coast. In the clearer and drier spells we could see temperatures dip to a rather chilly 2C, which is enough for a ground frost. The ground, however, is wet and there's still quite a breeze around so it's only going to be light.
Saturday sees another spell of rain for the south and south east of Wales, elsewhere it's bright spells and showers. These are likely to be heavy. These showers continue all day and there's a chance of seeing more rain in the south west later in the day. Highs of just 8-9C, feeling rather cool.
More rain pushes across south Wales during the evening before another day of bright and sunny spells with a scattering of showers. It will be a another fresh feeling day with highs of 10C, but the breeze won't be too strong.
Another band of rain moves overnight Sunday into Monday and there will be rain to start the day before clearing later. Tuesday should be a drier and brighter day.
