UK long range weather forecast

Thursday is likely to be cloudy for most with early morning fog possible, occasional rain in the northwest with a possibility of lighter, scattered showers extending further eastwards at times. During the following few days, a continuation of more settled weather is favoured for most of the UK, with a chance of unsettled weather mainly limited to the northwest in the form of rain, showers and potentially some stronger winds. Temperatures are expected to be around or a little below average through the start of December, which will feel cold compared to recent mild conditions, particularly in the south and east. If unsettled weather does return to the northwest, temperatures may recover to normal here.

Updated:

Confidence remains low for this period. Conditions are expected to be more settled than of late, with the potential for high pressure to be located close to the UK, at least at first. With time, however, we may see a return to frontal systems moving in from the west, with drier interludes between. Whilst temperatures may average out close to normal overall, colder conditions are possible at times, with a risk of overnight frost and fog.
