What’s new vs what’s known

New today/this week

As of Tuesday, the Met Office has issued specific warnings detailing the potential for snow accumulation of 2-5cm at lower levels and 5-10cm at higher altitudes in northern and eastern Scotland. Additional warnings are expected to be issued throughout the week as the weather system evolves, with the risk of 'thundersnow' in some areas.

What was already established

Prior to this cold spell, November was unseasonably mild, leading to expectations of a relatively warm winter. However, the abrupt change brought by Arctic air has led to a reassessment of weather forecasts and preparedness for severe winter conditions.

Impact for the UK

Consumers and households

The drop in temperatures and the expected snow and ice could significantly affect daily life. Households should prepare for potential disruptions to travel, including delays in public transport and the need for additional health services for vulnerable individuals due to cold-related health risks. Heating bills may also rise as families attempt to maintain warmth in their homes.

Businesses and jobs

Businesses should anticipate potential supply chain disruptions due to adverse weather conditions. Industries reliant on transport, such as logistics and retail, may face challenges as snow accumulates and ice forms on roads. Employers are advised to monitor conditions and prepare for possible delays in operations.

Policy and regulation

The UK government and local authorities are likely to review emergency services protocols in response to the cold-health alerts. This may include mobilising additional resources for healthcare and social services to support vulnerable populations during the cold snap.

Numbers that matter

5-10 cm: Potential snow accumulation forecasted for higher ground in Scotland.
-12°C: Expected minimum temperatures in rural Scotland.
3-6°C: Deviation from average temperatures in November prior to the cold snap.
