The monthly outlook is based on output from global forecasting models and our own analysis.
Forecast Issued 01/12/2018
Close to or slightly above average.
Slightly above or above average.
All regions have showers or longer spells of rain and over high ground in the north there is a risk of some snow. There will also be windy periods and the possibility of gales or severe gales. The south generally stays mild or very mild, but the north will be colder at times.
Becoming cold. [Forecast confidence is moderate]
It remains unsettled early on with further showers or longer spells of rain. In the north colder conditions develop and during the middle of the week they extend southwards across most of the UK. However, it may stay milder in the south west. Through the rest of the period it is expected to be cold, although possibly more changeable and milder in the far north west. Nighttime frosts develop readily where skies clear and there is a risk of wintry showers in central and eastern counties. Some of them could fall as snow down to low levels.
Cold and wintry start. [Forecast confidence is low]
A cold start is expected and there is a risk of wintry showers. More changeable weather should return, bringing an increasing risk of rain and snow. The greatest chance of snow is over high ground and in the north. The rest of the period is forecast to be mixed. Temperatures probably recover and in the south it could be quite mild for a while. Later on temperatures drop in the north and there is a chance of the colder air gradually spreading southwards. That leads to a possibility of snow, especially in the north and over high ground.
Important note about long range weather forecasts: It is considered impossible to say with certainty what the weather will be like more than a few days ahead in the UK. Long range forecasts on TheWeatherOutlook have not been independently verified, and we make no claims for their accuracy. A range of factors including seasonal computer models, recent weather patterns, sea surface temperatures and teleconnections are considered when making the forecasts.
