The capital is bracing for a significant and prolonged period of wintry weather, with forecasters warning of a growing risk of snow from Sunday and an amber cold-health alert now in force across much of England.
Frosty Days and Icy Nights Ahead
Londoners are set for a spell of dry but bitterly cold conditions over the weekend, characterised by crisp winter sunshine, persistent frosts, and temperatures struggling to climb. Both the Met Office and BBC are predicting daytime highs will hover around a chilly 2–4°C, with overnight lows plunging well below freezing. A biting northerly wind will make it feel even colder.
The detailed forecast indicates a hard frost on Saturday night with temperatures dropping to around -4°C. Sunday will see more sunshine before the risk of snow increases later in the day and into Monday.
Increasing Risk of Snow Disruption
While uncertainty remains, meteorologists state that the chance of snow developing from Sunday night into early next week is increasing. The Met Office outlook for Tuesday and Wednesday also highlights the potential for further rain or snow as weather systems move in from the Atlantic and collide with the entrenched cold air over the UK.
The BBC's forecast mirrors this, showing symbols for snow and sleet appearing from midweek. The key risk is that any precipitation falling on the frozen ground could lead to icy patches and potential travel disruption.
Amber Health Alert Issued for London
In response to the severe cold, the UK Health Security Agency (UKHSA) has activated an amber cold-health alert for London and most of England. This alert is active from 8pm on 2 January until 10am on 9 January.
An amber warning signifies that the weather conditions are likely to impact the whole health service significantly. Officials have warned of several serious consequences:
- A probable increase in deaths among the vulnerable, particularly the over-65s and those with pre-existing health conditions.
- Increased pressure on NHS services.
- Indoor temperatures in some buildings falling below the recommended 18°C.
- Wider impacts on transport networks, energy demand, and staffing levels.
Authorities are urging the public to check on vulnerable friends, family, and neighbours, ensure homes are heated adequately where possible, and take extra care when travelling in potentially icy conditions.
Looking further ahead, some milder conditions may begin to edge in later next week. However, forecasters caution that the setup remains primed for further snow, especially if Atlantic rain continues to meet the lingering cold air over the country.
Met Office Chief Meteorologist Rebekah Hicks emphasised the severity of the situation: "Arctic air and brisk northerly winds are gripping the UK... Bitterly cold conditions will persist through the weekend and into next week." She urged people to stay #WeatherAware and plan for hazardous icy surfaces.
