Heavy rain is on the cards for millions of Brits tomorrow as a shift in the jet stream is expected.
Temperatures have dropped to around normal for this time of year following a record-breaking May heatwave, during which the mercury rose above 35C in some areas – marking the hottest temperatures ever for May.
However, thunderstorms and rain have followed in many areas. And while the Met Office says some “dry and bright weather” can be expected first thing tomorrow, forecasters add: “It is not going to last.”
Met Office meteorologist Aidan McGivern says a new weather system “with a stronger-than-average and more south-shifted jet stream” will bring low pressure to our shores tomorrow.
“That means it swiftly turns wet across Northern Ireland, Wales and the South West first thing Wednesday morning, ” he said. “[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.”
Mr McGivern added that, even as skies clear and brighten in the afternoon, there will still be “a lot of showers returning to Northern Ireland, the north and central England, as well as Wales in particular”.

The Met Office earlier said highs of 21C could be expected in southern areas on Wednesday, with the mercury peaking at 19C up north. Similar temperatures are expected throughout the week.
The BBC weather forecast for this week states: “[Wednesday] will be cloudy and windy with outbreaks of rain pushing eastwards, these occasionally heavy with a risk of thunder in the north. Sunny spells developing in the south later in the afternoon.
“A mix of sunshine and heavy showers on Thursday. Risk of thunderstorms in the afternoon. Friday looks to see sunny spells interspersed with showers in the west and north. Drier elsewhere. Saturday will see mostly cloudy skies with a chance of light rain in western areas.”
