Staying notably chilly for mid-May through this week as air from the north-northwest prevails, with showers heavy at times and containing hail with snow over the tops, but over the weekend a front will edge in and bring a change to westerly winds. Next week may see ridging across England and Wales giving drier conditions, but occasional rain and blustery south-westerly winds for Scotland.
