Met Office Forecasts Temperature Drop in Christmas Weather Update
The Met Office has released its long-range weather forecast for Christmas Day, hinting at a significant temperature drop. As Christmas approaches, a shift in weather patterns is expected, moving from unsettled and wet conditions to a quieter and cooler atmosphere.
Current Weather Trends
In the lead-up to Christmas, the UK is experiencing unsettled weather. Heavy rain and strong winds are anticipated, particularly affecting southern England and south Wales. Rainfall totals may reach up to 50mm, with gusts of wind reaching up to 70mph in coastal regions.
Rain and Wind Forecast
- Heavy rain expected across southern England and Wales.
- Wind gusts could reach 60-70mph in exposed areas.
- Yellow weather warnings issued for rain across southern regions.
After the rain clears, weather conditions are expected to improve temporarily on Friday, with many regions experiencing a brief respite. The day will be drier and sunnier, although some showers may persist in the north and west.
Upcoming Weather Changes
This weekend, another frontal system is projected to approach from the west. However, progress may be limited, with the heaviest rainfall expected in western parts of the UK. As the ground is already saturated from previous rainfall, even minor rain could enhance flooding risks.
Flooding Concerns
- Cumulative rainfall totals of 100-150mm possible in western areas by Sunday.
- Flood warnings may be issued as conditions change.
Shift to High Pressure
By Monday, December 22, a transition in the weather pattern is anticipated. High pressure is expected to build from the north and northeast, promising more stable weather conditions. This shift could lead to drier weather as we approach Christmas.
Christmas Weather Outlook
The Met Office suggests a 50-60% chance that high pressure will dominate the UK’s weather by Christmas Eve. This would lead to lighter winds, drier conditions, and possible sunny spells.
Temperature Predictions
Daytime temperatures are likely to remain slightly below average, around 5 to 7°C. With high pressure in place, overnight frosts will occur more frequently, especially in rural areas. Fog and mist patches may also develop during this time.
Possibility of a White Christmas
- Light and patchy wintry showers may occur along eastern coasts.
- Currently, the chances of widespread snowfall are low.
- Only one snowflake is needed for a “white Christmas.”
High pressure is expected to persist into Boxing Day, keeping conditions generally settled. However, the eastern flow may lead to further drops in temperature, creating a more noticeable chill.
In summary, the festive period will likely experience temperature drops and stable weather, along with increased overnight frost and potential travel impacts due to lingering fog. Overall, it appears to be a welcome change after a turbulent weather month.
