A northwest flow across the UK and Ireland on Thursday bringing colder air to all areas. Showery rain affecting the far south of England first thing, this clearing quickly. Showers expected across the north of Scotland and further scattered showers down coasts and hills generally across the country. Dry and bright for most elsewhere. A brisk wind further north and east making conditions feel particularly chilly. Highs at 8 to 12C.
Showers across northern and western Scotland continue overnight, these possibly merging into more organised spells of rain across the northwest Highlands into the Cairngorms and central parts of Scotland later. Showers also continue down some western coasts. Mainly dry with clear skies elsewhere. Lows at 3 to 9C but again in some places reaching close to freezing away from towns and cities and towards higher ground.
A ridge of high pressure builds across Ireland and the rest of the UK on Friday. It stays cool throughout the day with broken cloud and sunny spells for many, the best of it to the west and south. Through Scotland and into northern England some cloud and showery periods of rain is expected at times here. This rain tending to fade in the late afternoon and early evening. Highs at 8C in northern Scotland, 12C in southern England.
The ridge of high pressure remains over much of England and parts of Wales on Saturday with largely dry weather here, although breezy and with increased cloud cover from the west. Meanwhile, rain moves eastwards across Ireland and much of Scotland and will be reaching west Wales later, becoming heavy for a time. Highs at 11 to 15C.
