High pressure is likely to build from the south, close to or over the UK throughout this period, with generally settled conditions prevailing for many. Cloud amounts will be variable and often large, with a chance of some fog developing under clearer spells, which could be slow to clear. Frontal systems may affect some parts of the UK though, these more likely towards the northwest of the UK, bringing some rain and windier conditions here, especially to western Scotland. Temperatures are likely to be generally around or a little above average in the north and west, although southern and eastern parts may be colder at times, especially where overnight fog and frost is slow to clear.

High pressure may initially dominate, especially in the south, bringing quiet, grey, and cool conditions here. Northern parts are more-likely to be unsettled but milder. This pattern will likely spread across the whole UK by the end of the period, leading to milder conditions with periods of rain and strong winds more widely.
