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.
The forecast headline is for a milder than average winter. There is considered to be a greater chance of above rather than below average rainfall. Away from high ground in the north snow is most likely during the second half of January and the middle of February.
Above the 30 year average taken over the three month period as a whole.
Rainfall levels are forecast to be slightly above average.
Close to average.
The start of the month is expected to bring a good deal of dry and frosty weather, although the extent of this could become increasingly limited due to cloud cover. In the north it becomes more unsettled and milder during the second half of the first week. The unsettled conditions then spread southwards. Towards the end of the period colder and changeable conditions are likely to develop. The risk of snow increases in the north.
A rather changeable and chilly first week is forecast. In the north it could be cold enough for snow at times, particularly over high ground. The risk of snow spreading further south is considered quite low but it is not discounted. Through the rest of the period it probably remains changeable with temperatures becoming close to the seasonal average.
Often unsettled or even stormy conditions are predicted with above average rainfall. Despite the likelihood of above average temperatures over the period as whole, it could at times be cold enough for substantial snowfall over higher ground in the north.
Unsettled conditions are expected to persist but the chance of colder weather increases. A cold period lasting for several days, which brings the risk of snow, could be sandwiched into this period. Milder and more unsettled conditions are likely earlier and later.
Slightly above average.
Quite unsettled weather is forecast for much of the period with temperatures generally often close to average, but above average at times in the south. Rainfall levels probably slightly above the average with drier spells most frequent in the south and east.
The middle part of the month may bring a spell of colder weather with a risk of sleet and snow for a time in all regions. Milder and unsettled conditions are considered likely to return in the north and west. Quieter and drier spells are more likely in the south and east.
