A small frontal system circulates over eastern England during the day, gradually moving away into Europe, but brings a cold and wet day for East Anglia. Areas of showery rain affect southern England, improving into afternoon to give brighter spells. Drier for Wales, southwest England and much of Ireland, often dry with sunny spells. Showery conditions affect northern England and Scotland, snow on the mountain tops. Highs 10 to 16C.
