Chilly in the east, damp and cloudy to the west. A cold wind all week and horrible on Saturday
The pushing and shoving of cold and dry weather from the east against milder, cloudy and damp conditions from the Atlantic. Overnight into Saturday, the two will collide with wet and windy weather from the west hitting the colder air in the east and heavy rain, strong winds and snow will result.
It is chilly in East Anglia with clearer skies and temperatures around zero. Further west, there is a weak frontal band bringing patchy light rain for the west coast of Scotland, Co. Antrim and Down, SW Wales and SW England. There is a SE wind which picks up during the day and that will make it feel colder.
Through the day the easterly flow has a bit of a win, nudging the fading front back towards Ireland. Many places cheer up, with brighter skies, even a bit of sunshine for parts of England, mainly in the east and the far north of Scotland. The grey damp theme continues north/south for western Britain and eastern Ireland.
It will turn chilly tonight with temperatures dipping near to freezing and a brisk SE wind across Britain. Northern Ireland will also be windy but milder at 6 or 7C. An occluding front will edge in from the SW bringing more cloud and patchy rain with temperatures also around 7C in the far SW of Britain. High pressure is settled over Scandinavia, continuing the feed of colder air from the continent.
By the start of Thursday, there will be this frontal band edging in from the SW with cloud and rain and milder air. The flow across the North Sea will bring in some cloud with a few showery bits. These will mostly be of rain but will be of sleet and snow inland over the hills. In-between there will be sunshine and clearer skies, but it will be a cold feeling day. This next band from the west also falters and fades as the cloud and rain lingers over Northern Ireland and the far SW of Britain during Thursday night keeping temperatures above zero.
For much of Britain, it will be cold with frost as the cold brisk wind continues for north and west Scotland, through the Irish Sea and for Northern Ireland.
After a cold start, there will be a lot of fair weather about on Friday. Still a few rain or wintry showers for NE Britain even down to the Humber. Northern Ireland keeps the cloud and patchy rain with a brisk nippy wind. Elsewhere bright and fine but cold, around 3 to 5C.
If you are off out on Friday evening, there will be more rain for Northern Ireland with a cold S wind. Much of Britain will be cold, clear but dry as the frost returns. Still windy in the far north and west with a few showery bits.
So, Friday night and Saturday could be the days to watch this week. There is a snow signal as weather fronts finally make progress across the UK and hit the cold air. It’s mainly NW Britain down to the Peak District and for Scotland, over the hills. Although there could be snow to lower levels for northern Britain for a time. Further frontal bands follow the first with milder air, so rain will follow, even if you do see some early snow, so could then just mean slush. There could be more snow later in the day coming into SW Scotland as milder air tucks over southern Britain. Overall Saturday looks horrible. Cold, wet, wintry and windy with strong SE winds and a real chill in the damp air.
