Tue 26 Nov Wales

An unsettled start, with rain or showers in places, and perhaps also some strong winds for a time. Temperatures back towards average for most places, but still mild in the southeast. High pressure is likely to build for a time, particularly across northern areas, bringing an increased risk of some fog and frost. However, this is likely to migrate eastwards during the second half of next week, potentially allowing some outbreaks of rain to move into some western and perhaps southern areas. Into December, and while signals are mixed it looks most likely that high pressure may re-assert itself close to or over the UK, with temperatures generally near average, but some overnight frost is likely, and rather cold by day where any fog persists.
