Parts of the UK Prepare for Possible Heatwave
Several regions in the UK are anticipating a potential heatwave as temperatures are forecast to reach up to 28C ahead of the upcoming bank holiday weekend. This follows a recent spell of unusually cold weather experienced last week.
Over the next few days, temperatures are expected to return to near average levels before rising further. Although drier conditions are predicted after midweek, rain is still expected at times.
Showers have been widespread to start the week
Warmer Weather Expected This Week After Wet Start
By Wednesday, temperatures are forecast to reach 21C (70F). Most areas will experience dry weather on Thursday and Friday, with temperatures climbing to as high as 28C (82F) in south-eastern England.
This will mark the warmest weather recorded so far this year, surpassing the 26.6 Celsius (79.8F) noted at Kew Gardens during an unusually warm early April.
High pressure situated to the east on Friday will bring a warm southerly breeze; however, a weather front poses a risk of rain in western regions.
The primary cause of the warming trend is a shift in wind direction. Last week's cold conditions were due to winds blowing from the north. Earlier this week, south-westerly winds from the Atlantic, coupled with areas of low pressure, influenced the weather pattern. Later in the week, winds will shift to come from the south, leading to a significant temperature increase.
Will There Be a Heatwave?
The Met Office defines a heatwave in the UK as a period of at least three consecutive days with daily maximum temperatures exceeding a county-specific threshold, indicating unusually hot weather for that time of year.
The heatwave threshold varies across the UK; for example, in Greater London it is 28 Celsius, while in Northern Ireland it is 25 Celsius.
It is possible that some locations could meet the heatwave criteria during Friday, Saturday, and Sunday. Currently, counties such as Herefordshire and Worcestershire appear most likely to experience these conditions.
However, the development of showers over the bank holiday weekend could affect this outcome.
Maximum temperatures forecast for Friday and Sunday
Bank Holiday Weather Outlook
Overall, the forecast indicates warm conditions for many areas during the long weekend, with temperatures ranging between 20-26 Celsius.
Nevertheless, not all regions are expected to remain dry. Showers are likely on Saturday, particularly in Scotland, Wales, and western parts of England. On Sunday, showers should be limited to southern England as an area of high pressure re-establishes itself across northern parts of the UK.
Monday is expected to be dry, although an easterly wind is anticipated to develop, which will keep coastal areas along the North Sea cooler.
The precise weather details for the weekend remain uncertain. It is advisable to stay updated via the BBC Weather app and the Weather for the Week Ahead.
