Pressure starting to build from the east through Saturday. There will be a fair amount of cloud once again on Saturday morning, and a few spots of drizzle on the hills. However, some brighter spells breaking through the cloud as the day progresses, although this triggering one or two showers in the Midlands and northern England. As winds fall light fog is expected to become widespread into the evening. Highs at 8 to 12C.
A ridge of high pressure extending through the country on Sunday. This brings with it the risk of some widespread fog through England and Wales. The fog lifting to sunny spells, although perhaps lasting in some places throughout. Thicker cloud and some rain in northern and western Scotland. Highs at 9 to 12C.
With high pressure holding through the country on Monday, there is the potential for another foggy day in much of England and Wales. It is likely to be the Midlands, east Anglia and Wales that see the densest of the fog, and this may not lift all day. Weak fronts moving into Scotland bringing rain here, but elsewhere it should be dry. Highs near 5C in northwest Scotland, 8C in southern England.
On Tuesday a cold front is expected to pass southwards as a ridge of high pressure builds from the west. The front takes some rain through central and southern England and Wales, with much brighter and cooler weather following behind. A few showers affecting northern and western Scotland where some may be heavy and wintry. Highs at 4 to 8C.
An area of high pressure builds through southern Ireland and the UK on Wednesday. There will still be showers over northern and western Scotland, a few also in the far southeast of England. It may be frosty at first with some fog in central and northern England and Wales. This should clear to leave the day dry and bright for most, but chilly at 4 to 7C.
A widespread frost overnight into Thursday. There may be more cloud in Scotland and the far north of England, preventing a frost here. Fog patches too, these freezing in places. Where the fog does clear the day will be dry and bright with sunny spells, but where it lingers it is likely to be feeling very cold. Cloudier in much of Scotland. Highs at 2 to 8C.
