Britons anticipating pleasant weather this week should enjoy it while they can before a chilly Arctic blast brings temperatures as low as -6C. Following a weekend cold snap, a period of mild weather is expected as low-pressure systems move northward and the UK is influenced by two high-pressure systems from southern and central Europe.
The upcoming days promise to deliver the warmest temperatures of the year so far, with the Met Office forecasting highs of up to 20C in western England and Wales on Wednesday. This surpasses temperatures in popular holiday destinations like Ibiza. While England could see temperatures reaching 18C, Northern Ireland and Scotland are likely to experience slightly cooler conditions.
However, it is premature to pack away winter gear as temperatures are projected to drop again towards the end of the month. Cold polar air associated with a series of low-pressure systems may bring temperatures down to -5C in Scotland and potentially -6C in Wales, with other regions also experiencing near or below freezing temperatures.
Weather models indicate heavy snowfall on March 30 in the Midlands, central and northern Wales, as well as expected flurries in northern England and Scotland. The Met Office’s forecast for March 21-30 suggests a predominantly dry start with temperatures around or slightly above average, although parts of the south may feel cooler due to developing easterly winds.
Despite the settled conditions and spring sunshine, there are indications of possible showers or rain returning later in the period, particularly in the south. Ahead of this, a week of warm weather is in store, with the Met Office’s Chief Forecaster Dan Harris noting that Wednesday is likely to be the warmest day, with temperatures possibly reaching 20C in parts of west Wales and western England.
The week ahead will feature significant temperature variations between day and night, with clear skies leading to chilly nights following warmer days, potentially resulting in air frost in some areas.
