Everyone is dreaming of a white Christmas, and with the big day almost a month away, snow in Southampton on December 25 has not been ruled out yet.

Only one snowflake needs to be observed falling during the 24 hours of December 25 for the Met Office to declare a white Christmas, which has been the case in parts of the UK every year since 2020.

While the Met Office confirmed to the Daily Echo that they cannot accurately predict snow more than five days ahead, hopes of snow in Southampton on Santa’s day off have been given a boost by the weather expert's long range forecast.

This projection attempts to sum up the weather for the entirety of the UK four weeks in advance, and the two weeks between November 27 and December 11 could bring a greater risk of snow due to colder air.

A spokesperson from the Met Office said: “When looking at forecasts beyond five days into the future the chaotic nature of the atmosphere starts to come into play - small events currently over the Atlantic can have potentially significant impacts on our weather in the UK in several days' time.

“For this reason, our text forecasts for 5 days and beyond are written on the scale of the UK as a whole.”

The Met Office’s Deputy Chief Meteorologist Mark Sidaway did say that some long-range tests can help weather experts understand the chances of snowfall in advance.

He said: “Different projections of the future are run multiple times through weather forecasting models.

“Often these will be quite similar at short ranges, but by the time you get weeks ahead, these can have a significant range of possible weather conditions in the future.

“Certainty will tend to increase as we get closer to the time, and the best indication of impactful snow in the forecast would be when a Met Office National Severe Weather Warning is issued.”
