A cold northwesterly flow covers the country through Saturday as a ridge of high pressure builds fro an anticyclone located to the southwest of Ireland.
A showery trough will be moving eastwards, this indicating the unstable nature of the airmass.
I think for many the day is going to be a chilly one. There will be a mix of sunny spells and showers, but very few of these making it to the south coasts of England. Most of the showers will be focused over western parts of Wales, Scotland and Ireland, where some of them may be on the heavy side.
A tendency for the showers to fade away from western Wales and western England in the afternoon and evening.
Winds mainly NW 14-18kt (F4-F5) but WNW 12-15kt (F4) across southeast England.


An unstable northwesterly flow covers the country again through today. A weak ridge of high pressure is going to be build through all parts, ahead of Atlantic frontal systems moving into western Scotland.
There will be showers affecting eastern coasts of the country, and some of these may be heavy at times, possibly thundery.
The showers will be fading away through the course of the day as the front approaches from the Atlantic. This brings increased cloud and eventually some outbreaks of rain to Ireland and the west of Scotland.
Winds NW 14-19kt (F4-F5) at first, then backing to W 12-15kt (F4) later.
