BBC monthly outlook
Summary
Unsettled weather for the rest of December
Monday 24 December—Sunday 6 January
Staying mild with some very wet and windy weather
As we end December, there doesn't seem to be much change in the weather pattern, with low pressure systems moving across the UK bringing plenty of fronts, strong winds, and rain, along with milder temperatures. Western areas of the UK are expected to be the wettest and there are indications that rainfall could be well-above normal for the time of year for some areas, with a risk of flooding.
Strong winds appear most likely towards the end of the month. The generally unsettled theme dominated by low pressure systems will mean that any lowland snow around Christmas is unlikely. However, a brief cold snap between fronts cannot be ruled out, so there is perhaps just the faintest glimmer that some may see a white Christmas. As we head into the new year, the Jet stream looks set to dip south, bringing the low pressure track across the UK and into the Continent. This will bring colder air into the north with Scotland likely to see some snow even down to low lying areas. Further south it will stay wet, windy, and milder than Scotland but generally a bit cooler than December.
Occasional and brief cold snaps in the south are possible after the cold fronts move through, which could bring the risk for wintry showers to low-lying areas at times.
Next Update
Although a white Christmas looks unlikely, could we some snow somewhere in the UK?
