Showers or longer spells of rain are likely to continue at first for many parts of the country, perhaps heavy at times, but gradually over the weekend the weather is expected to become more settled. Scotland and Northern Ireland are likely to see this change first, with spells of rain perhaps slower to clear further across the south. Into the following week, high pressure is expected to become more widely established.
