The Met Office has identified eight regions across the United Kingdom that are expected to experience heavy rainfall on Wednesday, as a significant change in the jet stream brings unsettled conditions. Following a record-breaking May heatwave that saw temperatures soar above 35°C in some areas, the weather is taking a dramatic turn.
Regions Affected by Heavy Rain
According to Met Office forecasts, the following areas will be most impacted: Northern Ireland, Wales, South West England, Central England, Eastern England, Northern England, Southern Scotland, and Central Scotland.
Weather System Details
Meteorologist Aidan McGivern explained that a new weather system, driven by a stronger-than-average and more south-shifted jet stream, will bring low pressure to the UK. He said: "That means it swiftly turns wet across Northern Ireland, Wales, and the South West first thing Wednesday morning. It will be a tricky rush hour as this rain moves north-eastwards, turning damp for central, eastern, and northern England by the afternoon, as well as central and southern Scotland."
He added that even as skies clear later, showers will persist in Northern Ireland, northern and central England, and Wales.
Temperature Outlook
The Met Office predicts highs of 21°C in southern areas on Wednesday, with northern regions reaching around 19°C. Similar temperatures are expected throughout the week.
BBC Forecast for the Week
The BBC forecast for Wednesday indicates cloudy and windy conditions with outbreaks of rain pushing eastwards, occasionally heavy with a risk of thunder in the north. Sunny spells are expected in the south later in the afternoon. Thursday will bring a mix of sunshine and heavy showers, with a risk of thunderstorms. Friday will see sunny spells and showers in the west and north, while Saturday remains mostly cloudy with a chance of light rain in western areas.
