UK Braces for Cold Snap After Warmest Weekend of 2025

Temperatures are set to plunge across the UK this week, with the Met Office warning of wintry showers and a potential polar vortex collapse later in March.

The UK experienced its warmest day of the year on Sunday, with temperatures reaching 19.7°C in Crosby, Merseyside, surpassing Saturday's 19.1°C in Cumbria.
A sharp drop in temperatures is expected starting Monday, with highs falling to single digits and overnight lows reaching -4°C in rural Scotland by Tuesday.
The Met Office has issued a 10-hour yellow fog warning for parts of northern England, including Durham and Newcastle, with potential travel disruptions due to reduced visibility.
Wintry showers are forecast for northern and eastern areas this week, with snow likely limited to higher altitudes, while frost returns to many regions overnight.
Forecasters report an 80% chance of a polar vortex collapse later in March, which could bring severe cold weather, though its exact impact remains uncertain.
