A chance of bright spells in the east, with showers feeding in from western coasts to begin the period. A chance of further cloud and persistent rain to move into parts of the west. Hill snow likely in the north. Temperatures generally around average, with a chance of strong winds along southern and northwestern coasts. 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 for some exposed areas. Potential for drier and brighter conditions in the east at times. Some showers are likely to turn wintry at higher elevations. Towards the end of the period, more settled conditions may develop with some cold interludes likely.
