Tue 6 Jan South West England

The recent spell of cold, northerly winds should begin to ease by the middle of next week, with snow showers in the north and east becoming lighter and less frequent. However, bands of rain seem likely to gradually move in off the Atlantic and, as these encounter the cold air entrenched over the UK, some further snowfall is possible, particularly in central and eastern areas, with rain more likely in the west. From next weekend, the outlook becomes more uncertain. Most likely is that conditions will be less cold than recently, but there still remains potential for further spells of snow, especially in northern and central areas. Further south and west, some milder interludes are possible, with the chance of some heavier rain and stronger winds at times.
