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. Winds will be light and clearer skies are likely, however this does not rule out the odd shower, especially around coasts. High pressure and settled weather will result in temperatures falling to closer to average, with overnight frosts and morning fog which could be slow to clear.
