Outlook for Thursday to Saturday:

Widespread frost and patchy fog to start Thursday, but dry and bright after this and into the weekend. Cold for the time of year with brisk winds which ease later.

After being initially settled with early frost, there will be an early transition to more unsettled conditions, with areas of low pressure moving in from the North Atlantic, bringing with it bands of rain and periods of windy weather. Between bands of rain, there will be some brighter, showery spells. Overall, this period is likely to be wetter than average for the majority of the country. Whilst colder conditions will be possible at times, it will often be mild, with temperatures near or a little above average for the time of year.

Changeable or unsettled conditions are expected initially, with Atlantic weather systems bringing spells of rain and strong winds at times, interspersed with brighter, showery periods. Through late November, low pressure may become slower-moving to the west of the UK, potentially bringing more prolonged rainfall, particularly to southern and western areas, along with a continued risk of strong winds. Into December, confidence becomes low, but there is a possibility that low pressure tracks shift further south as high pressure builds to the north. This could bring further rain at times to central and southern areas, while northern parts become somewhat drier. Temperatures will probably be near or slightly above average in the south, with an increasing chance of colder conditions extending southwards from the north into December.
