West vs EastAdded : Saturday at 15:41 Colder and sunnier conditions are developing across Britain and Ireland this weekend thanks to an area of high pressure building across northern parts of the country. This high isn't sticking around though and will be drifting away to the east during the next couple of days. However, it will become a large blocking feature to the east and so we get caught up in the middle of that high trying to hold on and Atlantic low pressure systems trying to push in from the west.
Here is the synoptic chart for Sunday:
That high sitting over southern Scotland bringing plenty of fine if rather cold weather to many areas, the only exceptions being across the far north and far south where those fronts will bring more in the way of cloud and some patchy rain or drizzle at times.
Another widespread frost forms on Sunday night, again turning severe across parts of the north:
However towards the southeast those brisk winds keep temperatures above freezing.
During the early part of next week the high starts to slip away to the east:
Subsequently frontal systems try to move in from the west and the winds back to a milder south/south-easterly direction:
The question marks come over how quickly those Atlantic frontal systems push eastwards bringing their associated rain bands with them. The latest GFS ► run was quite progressive with this idea and put much of the country under an Atlantic influence by Tuesday:
With further frontal systems moving in during the rest of the week:
However this morning's UKMO output made more of the high out to the east, and kept a colder continental flow feeding into the southeast of the country:
Therefore some finer details to be resolved for the coming week but it does look like the further north and west that you are the higher the chance of milder and more unsettled conditions moving in whilst further south and east it remains drier and more settled with somewhat colder temperatures.
