The Met Office snow weather forecast for the UK in January 2026 indicates a transition from mild, cloudy conditions to a significant cold snap towards the end of the month, with an increased risk of widespread snow and ice.While mid-January has seen average temperatures between 6°C and 10°C, forecasters have identified a 60% probability of sub-zero nights and disruptive snowfall occurring between January 27 and January 31, 2026. This shift is driven by Arctic maritime air masses battling Atlantic weather systems. Earlier in the month, the UK faced severe disruption from Storm Goretti, which brought over 50cm of snow to parts of Scotland and amber warnings for wind and snow across Wales and the Midlands.
Understanding Met Office Snow Warnings
The Met Office uses a color-coded National Severe Weather Warning Service (NSWWS) to alert the public to potential impacts from snow and ice. These warnings are based on a combination of the likelihood of the event occurring and the potential impact it may have on infrastructure, travel, and life.
Yellow, Amber, and Red Alerts
- Yellow Warning: Issued when low-level impacts are likely (e.g., travel delays) or when severe impacts are possible but the certainty is low.
- Amber Warning: Indicates an increased likelihood of severe weather that could disrupt plans, cause power cuts, and pose a risk to life.
- Red Warning: The highest level, reserved for dangerous weather expected to cause substantial disruption, widespread damage, and extreme danger to life.
In January 2026, the Met Office utilized amber warnings extensively during the passage of Storm Goretti, which saw communities in northern Scotland and Wales effectively cut off by heavy drifts and blizzard conditions.
The Science of Snow Forecasting
Forecasting snow in the UK is notoriously difficult because the temperature at the Earth’s surface often hovers very close to the freezing point ($0°C$). A difference of just $1°C$ or $2°C$ can determine whether a region experiences heavy rain, sleet, or a “whiteout” blizzard.
The Role of Altitude and Air Mass
Snow is far more likely at higher altitudes where the air remains below freezing. For every 100 meters of elevation, the temperature typically drops by about $0.6°C$ to $1°C$. This is why the Scottish Highlands and the Pennines often see significant accumulations while coastal cities like Liverpool or Brighton remain wet. The Met Office also monitors “Arctic maritime” air masses, which originate from the north and are the primary drivers of significant UK snowfall events.
Storm Goretti: 2026’s First Major Event
In early January 2026, Storm Goretti became a “multi-hazard” event, bringing a rare combination of 100mph winds in Cornwall and up to 20cm of snow in the Midlands. The storm highlighted the complexity of UK winters, where a single weather system can bring flooding to one county and blizzards to another just 50 miles away.
Met Office Chief Forecaster Neil Armstrong noted that the “rain-snow boundary” for Goretti was razor-thin. Areas in Wales and northern England bore the brunt of the snowfall, while London and the southeast experienced mostly heavy rain and wind. This event served as a stark reminder of why the Met Office issues “dual warnings” for wind and snow simultaneously.
Long Range Forecast: Late January 2026
The Met Office medium-range models suggest that from Thursday, January 22, a “battle” will commence between mild Atlantic air from the west and cold high pressure from the east. By the final week of January, there is an increased chance that the cold air will dominate, leading to a “renewed plunge” in temperatures.
Predicted Impacts (Jan 27–31)
- Widespread Frost: Most of the UK is likely to see sub-zero overnight temperatures.
- Commuter Disruption: Low-lying areas in the North and Midlands are at higher risk for sleet and snow during morning rush hours.
- Fog Hazards: Freezing fog is expected to impact major hubs like Manchester and Liverpool airports, potentially leading to de-icing delays.
Practical Information and Winter Planning
Essential Winter Tips
- Check the App: The Met Office mobile app provides hourly updates and allows you to set push notifications for weather warnings in your specific postcode.
- Vehicle Prep: Ensure your car has adequate screen wash (rated for $-10°C$), a de-icer, and an emergency kit containing blankets and a shovel.
- Home Safety: Keep your heating at at least $18°C$ in rooms you use frequently to prevent pipes from freezing and to protect your health.

Technical Forecasting: The Freezing Level
The most critical factor in a Met Office snow forecast is the “freezing level”—the altitude at which the air temperature reaches $0°C$. In the UK, this level is incredibly fluid; it can drop to 200 feet (roughly 60 meters) above sea level in the morning and rise to 1,500 feet (450 meters) by the afternoon.
When the freezing level is near the surface, snow reaches the ground. However, if there is a “warm nose” of air just a few hundred meters up, the snow melts into sleet or rain. Forecasters use radiosondes (weather balloons) and high-resolution computer models to track these vertical temperature profiles. A shift of just $0.5°C$ can be the difference between a dusting of snow and a heavy rain shower.
The Influence of La Niña and NAO
The 2025/26 winter is officially influenced by a weak La Niña event. Historically, La Niña winters in the UK are characterized by higher variability. While early winter often brings milder, wetter Atlantic storms, late January and February frequently see a shift toward “blocking” high pressure over Scandinavia, which allows cold, dry air to flood in from the east.
Another key driver is the North Atlantic Oscillation (NAO). A “negative NAO” phase occurs when the pressure difference between Iceland and the Azores weakens. This slows the usual westerly winds, making it easier for Arctic maritime air masses to “topple” down over the UK, as seen during the cold snap that began in early January 2026.
Snow Measurement and Observation Tech
The Met Office utilizes a network of automated snow depth sensors to provide real-time data. These sensors use an ultrasonic transducer to transmit pulses toward the ground; the time it takes for the echo to return determines the depth of the snow.
Because the speed of sound varies with temperature, these sensors are paired with independent thermometers to ensure accuracy. This data is supplemented by manned observations at stations like Braemar and Altnaharra, where observers use traditional measuring rods. In 2026, the Met Office has also integrated “crowdsourced” data from social media and weather apps to verify snowfall in areas without official sensors.
Health and Infrastructure Preparedness
Winter weather in 2026 has prompted the UK Health Security Agency (UKHSA) to issue multiple Amber Cold Health Alerts. These alerts signify that cold weather could have a significant impact on health services and vulnerable populations, particularly those over 65 or with pre-existing conditions.
2026 Infrastructure Checklist:
- Energy Grid: National Grid ESO monitors “icing” on power lines, which can cause lines to snap during blizzards.
- Transport Scotland: Operates a fleet of over 200 gritters, including specialized “super-gritters” for the A9 and M74 routes.
- School Closures: Local authorities use Met Office “impact-based” warnings to decide on closures 12–24 hours in advance to help parents plan.
Future Outlook: February and March 2026
As we look beyond the late January 2026 cold risk, ensemble models suggest that February could see a return to more settled, albeit chilly, conditions. High pressure is favored to sit over or near the UK, which would lead to a high frequency of overnight frosts and freezing fog patches.
However, the “wildcard” for late winter 2026 remains the Polar Vortex. If a “Sudden Stratospheric Warming” event occurs in early February, it could trigger a prolonged period of easterly winds, significantly increasing the risk of a “late-season” heavy snow event in March, similar to the conditions seen in previous decades.
FAQs
What is the chance of snow today, January 19, 2026?
For most of the UK, today is largely cloudy and mild with some rain in the west. Snow is currently restricted to high ground in the far northeast of Scotland.
When will the next big snow hit the UK?
The Met Office points to a high probability of colder conditions and potential snow between January 27 and January 31, 2026.
How do I read a Met Office weather map?
Snow is typically shaded in white or light blue. Use the “layer” toggle on the Met Office website to see “Rain & Snow” specifically.
What does a ‘Beast from the East’ verdict mean?
It refers to a weather pattern where cold air from Scandinavia and Russia moves over the UK. The Met Office has warned of an increased risk of this pattern toward the end of January 2026.
How deep was the snow in Scotland in 2026?
Official stations recorded depths of up to 52cm in Aberdeenshire during the first week of January.
Can the Met Office predict snow 10 days in advance?
They can identify the risk and potential patterns (e.g., an Arctic plunge), but the exact location of snow is often only certain 12–24 hours before it falls.
Is the UK getting more snow due to climate change?
While the climate is warming overall, the Met Office notes that extreme weather events, including intense cold snaps and heavy bursts of snow, can still occur as atmospheric patterns shift.
What should I do in an Amber Snow Warning?
Think about changing your plans and avoid non-essential travel. Ensure you have supplies at home in case of power cuts or road closures.
What is ‘Thundersnow’?
It is a rare phenomenon where thunder and lightning occur during a snowstorm. It was reported in the Scottish Highlands during the cold snap in early January 2026.
Why does it often rain instead of snow in London?
London’s “Urban Heat Island” effect and its proximity to the relatively warm North Sea often keep temperatures just high enough to prevent snow from settling.
What is ‘Thundersnow’?
It is a rare weather event where thunder and lightning occur during a snowstorm. It was reported in the Scottish Highlands in early January 2026.
How does the Met Office use the ‘Warnings Matrix’?
The matrix plots the Impact (low to high) against the Likelihood (low to high). A “Red” warning is only issued when high impact is highly likely.
What is the ‘Jet Stream’s’ role in snow?
A “fragmented” jet stream, as seen in early January 2026, allowed Storm Goretti to develop rapidly and pull cold air into its southern flank.
