A changeable pattern is likely to continue, with areas of rain or showers affecting parts of the UK, particularly across the south and west. These will be interspersed with drier, colder interludes as shorter-lived ridges of high pressure develop. Weather patterns may become slower evolving during the latter stages of November, leading to some uncertainty over how much progress Atlantic frontal systems will make into the UK. Nonetheless, further rain or showers are likely at times, with the potential for some periods of strong winds. Incursions of milder air are likely towards the south, although it could remain on the cold side overall further north, where there is potential for overnight frosts and occasional wintry precipitation, particularly over higher ground.

The tracks of low pressure may shift farther south over the North Atlantic into December, as high pressure potentially builds between Scandinavia and Greenland. Whilst there remains some uncertainty over which of these features will have the greater influence on the weather in the UK, some rain is likely at times, particularly across southern areas, whilst northern and especially northwestern parts may become drier than normal. Milder incursions are possible in the south, although this pattern would also bring an increased chance of colder conditions developing, particularly in the north, along with associated winter hazards such as snow and ice.
