Sun 21 Dec South West England

The unsettled theme is likely to continue through the first part of this period, with further rain or showers affecting many parts at times, and often accompanied by rather windy conditions. In the run up to Christmas, there is a signal for less unsettled conditions to begin to take hold, with a greater chance of high pressure developing in the vicinity of the UK compared to the previous few weeks. Whilst the chance of impactful rain or strong winds should reduce, there may be an increasing incidence of overnight frost and fog, the latter perhaps taking its time to clear, given the time of year. A gradual reduction in temperatures seems likely, falling closer to average overall. Some cold days are possible, if or where any fog persists.
