Moving through the period, largely unsettled conditions are likely to persist, with the chance of further showers and longer spells of rain, heavy in places, with a chance of gales. Some showers are likely to turn wintry on hills at times. Towards the end of the period, more settled conditions are likely to develop, most likely with milder temperatures, but a chance of some brief colder interludes.
