Forecast Issued 30/11/2024
Important note about long range weather forecasts: It is 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.
The forecast headline is for a milder than average winter. Despite that, some cold snaps are still likely. Cold plunges from the north in the autumn months were more potent than has been the case in a number of recent years.

First half
Mixed weather is expected. Cold air pushes southwards early on, with wintry showers affecting the north and frost becoming quite widespread. However, it is likely to turn milder and more changeable quite quickly, and there is a risk of it becoming very windy. Another cold snap could then develop by the end of the first week. Through the second week the expectation is for it to be more settled. Therefore, the risk of nighttime frost and fog increases, particularly in the south and east. In the north and west there is a greater chance of wet and windy days.
Second half
On balance, rather mixed weather continues to be favoured. Therefore, dry conditions early on are likely to be replaced with wetter and windier ones in all regions. There is the potential for disruptive weather. In the north sleet or snow is possible at times, particularly over high ground. The expectation of unsettled conditions suggests a reduced risk of frost and fog relative to the norm.
Above average
The weather is expected to be mostly unsettled with above average amounts of rain. The possibility of very windy or even stormy spells is considered relatively high. Despite the likelihood of above average temperatures over the period as whole, it may be cold enough at times for snow in the north, especially over high ground where significant falls are possible.
Unsettled weather is expected for much of the time, with wet and windy periods in all regions. However, a colder and more settled spell could develop for a while, leading to frosts becoming more widespread. That would lead to the possibility of sleet or snow for a time when milder air started to return.
Precipitation
Slightly above average
Rather unsettled weather for much of the period. Rainfall levels will probably be slightly above the average with the driest spells in the south and east. Towards the middle of the month it may turn colder.
Cold snaps are possible, leading to a possibility of snow and frost. However, the prevailing weather patterns are likely to be supportive of milder and unsettled conditions for most of the time. The wettest and windiest spells are likely to be in the north and west, with quieter and drier ones more frequent in the south and east.
