Is This Christmas Going to Be Cold Enough for Snow?

As the festive season approaches, parts of Scotland are emerging as potential winners for a white Christmas in 2023.

This article explores the current weather patterns, implications for Christmas, and the likelihood of a white Christmas across the UK.

Last updated: 12 December 2023 (BST)

What’s happening now

With just a week until Christmas, the UK is set to experience a significant drop in temperatures. After a spell of milder weather, colder air is expected to sweep in from eastern Europe, causing average temperatures to hover around 6-9°C. This cooling trend could bring the possibility of sleet or snow, particularly in eastern regions, thanks to changes in wind patterns influenced by high and low pressure systems nearby.

Key takeaways

• Colder air from eastern Europe is expected to lower temperatures across the UK.
• A slight chance exists for colder air from Scandinavia, increasing snow possibilities.
• Weather patterns indicate potential showers, mainly affecting eastern areas.

Timeline: how we got here

The transition to colder weather has evolved over the past few weeks. Key milestones include:

• 1 December 2023: Temperatures began to rise, averaging around 12°C across much of the UK.
• 5 December 2023: Reports of heavy rainfall in areas like Cumbria and south Wales.
• 10 December 2023: Early indications of a shift towards colder weather as air from eastern Europe began to affect the UK.
• 12 December 2023: Current forecasts suggest colder conditions just in time for Christmas.

What’s new vs what’s known

New today/this week

Current forecasts indicate a notable drop in temperatures with the potential for snow showers in eastern areas. A shift in wind direction could also bring in colder air from Scandinavia, which would enhance the chances of a white Christmas, although it remains uncertain.

What was already established

Traditionally, a white Christmas in the UK is rare, with recent years seeing minimal snowfall on Christmas Day. Historical data shows that while snow can occur, the likelihood decreases significantly as the years progress.

Impact for the UK

Consumers and households

For UK households, the anticipated colder weather will likely result in increased heating costs. However, the absence of heavy rain will be a relief for areas that have recently experienced flooding, particularly in the northwest. Morning frost and fog may also cause travel disruptions, requiring extra caution for motorists.

Businesses and jobs

Retailers may benefit from the festive spirit as people rush to buy winter apparel and Christmas supplies. However, businesses in sectors reliant on outdoor activities, such as tourism, may face challenges if snow impacts travel plans. Overall, the quieter weather pattern should help many regions recuperate from the recent heavy rains.

Policy and regulation

The weather changes may prompt discussions among local councils regarding winter preparedness and road safety measures. While the current focus is on a potential white Christmas, authorities should remain vigilant about emergency services in case of adverse weather conditions.

Numbers that matter

• 6-9°C: Expected average temperatures across the UK in the coming week.
• 2°C: Temperature drop below the average for this time of year.
• 25%: Estimated chance of snowfall in eastern areas as colder air arrives.

Definitions and jargon buster

• White Christmas: Traditionally defined as having at least one snowflake fall on Christmas Day.
• High pressure system: A weather pattern that generally brings calm and clear conditions.
• Low pressure system: A weather pattern that usually leads to cloudiness and precipitation.

How to think about the next steps

Near term (0–4 weeks)

In the immediate future, homeowners should prepare for colder temperatures, ensuring heating systems are operational and that they have sufficient winter supplies. Travellers should remain updated on weather forecasts to avoid potential disruptions due to frost or fog.

Medium term (1–6 months)

As winter progresses, keeping an eye on weather patterns will be crucial for planning outdoor activities and travel. The potential for severe weather conditions should be considered by both consumers and businesses alike.

Signals to watch

• Updates on temperature changes throughout December.
• Weather alerts regarding potential snow or frost in eastern regions.
• Forecast shifts that may indicate significant changes in weather patterns.

Practical guidance

Do

• Monitor local weather forecasts for updates on temperature and precipitation.
• Ensure vehicles are winter-ready, with antifreeze levels topped up and tyres checked.
• Plan travel routes in advance, considering potential disruptions from frost or fog.

Don’t

• Underestimate the impact of cold weather on travel and outdoor plans.
• Neglect to prepare heating systems for the colder temperatures ahead.
• Ignore weather warnings issued by local authorities.

Checklist

• Review and restock winter supplies (heating fuel, blankets, etc.).
• Check vehicle winter readiness (tyres, wipers, etc.).
• Keep an emergency kit in your car (torch, food, water, etc.).

Risks, caveats, and uncertainties

While the forecasts indicate colder weather, the specifics can change quickly. The likelihood of snowfall varies based on wind direction and the exact positioning of high and low-pressure systems. Therefore, while a white Christmas is a possibility, it should not be taken for granted, especially given recent trends of declining snow events on Christmas Day.

Bottom line

As the festive season approaches, the potential for a white Christmas in parts of Scotland adds an element of excitement, although it remains uncertain for many. With colder temperatures on the horizon, residents should prepare for the possibility of frost and snow, while also enjoying the quieter weather that follows recent heavy rains.
