Saturday is likely to be dry for most of us and warm in the east. One or two showers remain possible.

However, parts of the southeast may stay mainly dry with some sunny spells. It will be windy at times, especially in the north, with a risk of gales here. Into the following week, there remains a lot of uncertainty, although we may continue to see spells of wet and windy weather, particularly in the northwest, with drier spells, mainly in the south. Temperatures will probably be near normal, though perhaps rather warm at times in the south.
