It’s Great Brrrr-itain! Nation shivers as temperatures plunge towards -7C overnight before heavy frost today
A cold spell brought the UK’s lowest temperatures of the year so far, with forecasters warning of a heavy frost after overnight readings fell close to -7C. The shift to colder weather matters for people at risk from the cold, with the first yellow cold-health alerts of the season issued for two regions.
Sennybridge in Wales recorded -6.6C, while Shap in Cumbria and Eskdalemuir in Dumfries and Galloway reached -6.5C. Saturday was expected to bring rain and showers in many areas, with dry, frosty spells in central and eastern England; milder conditions were forecast for Sunday, though rain, sleet and possible snow could affect northern Scotland, especially higher ground.
In short
- Sennybridge recorded the UK’s lowest temperature so far this year, at -6.6C.
- Yellow cold-health alerts covered the North West and West Midlands.
- Rain, frost and possible snow were forecast over the weekend.
Explained simply
The UK’s weather is shaped by Atlantic air, which often brings changeable conditions, and colder air moving in from the north or east. In winter, clear skies and light winds can allow heat to escape overnight, causing temperatures to fall and frost to form.
Cold weather can affect anyone, but older people, those with some health conditions and people in poorly heated homes may face greater risks. Public health agencies issue cold-health alerts to help services and communities prepare for conditions that could affect health.
The Met Office provides forecasts and warnings, while health agencies use alerts to advise care providers and the public. Frost and icy conditions can also make roads and pavements slippery and affect travel.
