A slow moving cold front is going to be training through Ireland and Scotland on Saturday morning, edging only slowly into Wales in the afternoon.
It looks set to be a wet day for many western areas, with some heavy periods of rain affecting southern and eastern par5ts of Scotland, northwest England and the west of Wales, although note that the eastward extent of the front is unclear at this time.
Across central, eastern and southern England the day is likely to be generally dry with sunny spells, although there is a low risk of a shower forming inland in the afternoon, triggered by the warm temperatures.
To the west of the front it should be brighter with some sunny spells. There will be showers, these associated with the trough moving into the west fo Scotland, and these could become heavy at times.
Winds mainly S 8-10kt (F3) ahead of the front, becoming S-SSW 12-14kt (F3-F4) behind it.


Low pressure is in control of conditions through Sunday. The low will be complex and extend from the west of Ireland into Scotland.
There will be some cloud and rain over the north of Scotland, as rain associated with the trough edges eastwards through northern and central parts of England through Sunday morning (although confidence is low in the timing of the rain).
Drier weather should follow to the west as a weak ridge of high pressure builds ahead of the next frontal system which will be moving in from the Atlantic.
Winds mainly SW 14-16kt (F4-F5) ahead of the rough in the south, becoming W 12-15kt (F4-F5) behind it. Mainly NW 11-14kt (F4) over Scotland.
