It looks like north and west Wales, maybe NW England and much of Northern Ireland, especially Co Down will turn wet again for the evening rush hour. This distinct boundary will mark a cooler evening in the north and a mild evening for much of England and Wales. It looks like the front will edge southwards overnight, so northern England, north Wales and the Peak District have a fresher end to the night.
By Wednesday morning the frontal band is mostly just cloud with a bit of coastal dampness for southern England. And yet you cannot discount that front; it will return. Much of the UK will have clear skies and sunshine. A brisk wind remains for Scotland, Northern Ireland and the Isle of Man and it will feel cool in that breeze. Blustery showers continue to blow into Western Scotland, with rainfall totals totting up. With lighter winds for southern Britain, Wednesday will feel better as the temperatures rise again Later in the day the low pressure will be just to the north of Scotland and high pressure building to the south. That front, the one we had to remember, begins to wave back in from the SW as a warm front. It will struggle within the high but could bring low cloud, murk and light rain into SW Britain for the start of Thursday.
With hardly any breeze for England and Wales, there could be fog about on Thursday morning. Further north it will be windy for northern Scotland and colder. We’ll have to see where the frontal boundary sits by then, but again it is a tale of clearer fresher blustery conditions in the north and milder, cloudy but calm weather for the south. And the rain band in the middle.
It looks like the frontal band pushes south for the start of Friday, after a cold night for northern Britain. Cooler NW winds begin to flow around the top of the high pressure. These winds then pickup, most noticeably on Saturday for eastern Britain, it will feel like winter. From the 20C of today in East Anglia to 11C and a brisk north wind at the end of the week.
