Temperatures have fallen to roughly typical levels for this time of year following a record-shattering May heatwave, during which the mercury climbed above 35C in some areas – marking the hottest temperatures ever for May.

Nevertheless, thunderstorms and rainfall have followed across many regions. 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.”, reports the Mirror.

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”.

Central Scotland The Met Office has forecast highs of 21C in southern regions on Wednesday, with temperatures reaching 19C further north. Similar conditions are anticipated throughout the remainder of the week.
