Central and northern parts of the UK will likely be in a colder but drier regime than of late with overnight frost, and some showers near windward coasts in particular which may be wintry on high ground in the north. However, across the south it is likely to be cloudier and wetter initially, with some uncertainty as to how quickly this clears away to the south. It is most likely that the bulk of the UK will experience drier and colder conditions into the first part of next week. Later in the period there is increasing uncertainty, but a trend towards more changeable conditions is possible, with some rain or showers in places, and perhaps some hill snow at times in the north. Temperatures overall may return to near average.

Whilst the expected weather patterns during late November are very uncertain, there is a greater than normal chance of spells of higher pressure towards the north or northwest of the UK and spells of lower pressure towards the south. This means that northern parts of the UK may be somewhat drier and a little colder than normal, with an enhanced risk of overnight frost and possibly fog, whilst southern and western parts may be wetter than normal, with temperatures near or a little above normal. All parts are likely to see some spells of wind and rain though, with hill snow possible, mainly in the north.
