The United Kingdom is poised to experience its hottest day of the year so far, with the Met Office confirming that temperatures are set to soar to nearly 20°C later this week. This prediction follows a period of strong winds that caused significant travel disruptions across much of the country over the weekend, with gusts reaching up to 70 mph.
Peak Temperatures Expected on Wednesday
According to Met Office spokesperson Ollie Claydon, the peak temperature and mildest day of the week will occur on Wednesday, March 18. "It is likely to be the warmest day of the year so far, potentially reaching 20°C in places," Claydon stated. He added that high temperatures in the teens are expected broadly across England and Wales, with the west of Wales anticipated to see the mercury rise to 20°C.
Weather Patterns Driving the Warm Spell
The warm weather is attributed to an area of high pressure establishing in the north of the UK, combined with warm southerly winds. This setup is not unusual as the country moves into meteorological spring, which runs from March 1 to May 31. Additionally, the Foehn effect—a phenomenon caused by east to south-easterly winds moving over higher ground—is contributing to the sunny forecast.
Claydon noted that there will be plenty of sunshine across Wales and England, though some areas may experience mist and fog initially, which will burn off throughout the day. However, the early spring temperatures will drop overnight, leading to a large diurnal range. This means that rural parts of England and Wales could still see spots of frost, despite the daytime warmth.
Context of Recent Weather
The current forecast comes after the warmest day of the year so far was recorded earlier in March, with temperatures hitting 19.2°C in London. The upcoming spike in temperatures marks a significant shift from the weekend's windy conditions, offering a respite and a taste of spring for many residents.
As the UK embraces this brief heatwave, the Met Office emphasizes that such weather patterns are typical for the season, driven by high pressure and specific wind effects. Residents are advised to enjoy the sunshine while being mindful of the cooler overnight temperatures that may follow.
