UK long range weather forecast
Generally unsettled across the north at the start of the period, with strong west or southwesterly winds bringing periods of heavy or persistent rain and a risk of gales at times. Likely to be drier and brighter across many central, eastern and southern locations, though periods of rain cannot be ruled out, with lighter winds in the south leading to an increasing chance of overnight fog. As we go through the period, these more settled conditions in the south are likely to spread to most areas, with spells of rain and wind becoming less frequent and tending to be confined to the north and northwest. Temperatures likely remaining rather mild, though a risk of frost is possible during some colder interludes.
Updated:
Heading into the Christmas period, widespread settled conditions are likely. Temperatures perhaps close to or slightly above average for this time of year, however some colder interludes may bring a risk of frost at times. The last week of December and into early January is looking to remain settled, with an increasing chance of frost and fog during clearer spells for Christmas and towards New Year.
