Fri 5 Dec South West England

Likely a continuation of the unsettled conditions see for much of the week. Initially a weakening frontal zone will bring cloud and some patchy rain and drizzle, mostly to northern and eastern areas. Following this winds are likely to fall light, and this could allow some fairly widespread mist and fog to form on Friday morning. However this should readily lift as winds begin to freshen once more ahead of a further band of rain expected to reach western areas later on Friday. This could bring a spell of locally heavy rain as it moves east across the country, particularly on hills exposed to the strong southerly winds. Thereafter likely to remain unsettled into the weekend, with further rain or showers for most. Temperatures not far from average throughout.
