BBC Weather forecasted a significant drop in temperatures for Tuesday evening as a high-pressure area moves in across the UK, bringing in thick cloud across Scotland and light winds in the rest of the country. BBC Weather forecaster Matt Taylor warned thermometers will hit highs of 21C in the south of the country mere days after Britons basked in 27C sunshine. The BBC Weather meteorologist said: “Not a bad day ahead. Most places are going to stay dry, there’s going to be a fair bit of sunshine around as well.
“We got high-pressure moving in from the Atlantic – that stops the rain cloud building. Just round the top edge of that high pressure though we will see weather fronts close in towards Northern Scotland later, to West Scotland now.
“A bit of a breeze blowing but that will ease through the day. Some cloud leftover from last night on the English Channel so it is a bit grey around the Channel Islands and across parts of Cornwall, and various amounts of cloud elsewhere.”
Mr Taylor continued: “That will come and go, we’ll see some sunshine, sometimes a little bit hazy at times, particularly across Northern Ireland and Northern England and later the cloud thickens up into western Scotland. Could see some patchy rain by the end of the day.
“After the showers most will be dry throughout with some sunshine and blue skies overhead. Not especially warm after a chilly start but pleasant enough this time of the year, 15C to 21C.
“With light winds, that should still feel reasonably pleasant.”
Mr Taylor added: “Temperatures are going to drop quickly once again, down to single figures quite widely – could lead to some mist and fog and patchy, the main exception being the far north of Scotland where we see cloud and outbreaks of rain become a bit heavier, a bit persistent particularly for the Highlands.”
Forecasters show cooler temperatures will grip Scotland during the week, with persistent rain battering the region.
Met Office meteorologist Alex Deakin said: “There will be more sunshine on offer on Tuesday before we get there though there will be a little bit of chilly temperatures overnight.
“Temperatures will be well down into single figures particularly over Northern Ireland and southern Scotland, northern England and North Wales.
“A few places the temperatures will plummet maybe down to five or six degrees even lower than that in some sheltered spots.
“It will be a chilly start to Wednesday.”
On Tuesday the south and south-west are expected to get the best of the day’s weather and the far north could see the odd shower.
The warm and sunny conditions look set to remain for the rest of the week although the light winds will also be present with temperatures rising as the week progresses.
Northern parts will see some rain and drizzle and the nights could get chilly and some morning fog and mist could be present first thing but these will quickly clear away.
