UK weather forecast – Brits to bask in 20C tomorrow before rain and cold plunge this week

BRITS are set to enjoy balmy weather of 20C tomorrow but it won’t last long as temperatures are set to plummet and rain is headed our way later this week.

It was a bright, fine day in most parts in the UK with the top temperature hitting 20.5C in Achnagart in Scotland.

Some mist and fog is expected to form overnight in most parts but this will clear away bringing some fine weather tomorrow.

Tuesday is due to be mostly dry and bright for most of the country except for the far west where cloud and patchy rain is expected.

Temperatures could even top 20C, according to the Met Office forecast.

Pollen levels are also expected to be high in most parts apart from the west, where the risk is moderate, and Northern Ireland.

But conditions are expected to worsen as the week continues and heads into the May bank holiday.

The Met Office says though there will be some dry and bright patches as the week progresses.

Friday should see much colder weather as arctic air plunges southwards and the north could see some wintry showers.

Elsewhere could see widespread frost and high ground could see sleet falling in Scotland.

But Brits can expect to enjoy higher than average temperatures in the coming months which is likely to last at least until the beginning of June.

The Met Office’s long-range weather forecast – which covers a three month period – sees a Spanish plume hitting these shores bringing with it some sizzling temperatures.

And Weather Outlook forecaster Brian Gaze believes highs of 28C could arrive in Britain as early as May as warm air blows in from Spain.

He said: “28C would not be a surprise later in May, with warm air expected to arrive from southern Europe, known as a ‘Spanish plume’.”

Although it’s not yet possible to predict exactly how hot it will get in coming months, the long-range weather outlook is currently looking on the warmer side over the coming weeks.

Met Office meteorologist Sarah Kent told The Sun Online: “The forecast is based on probabilities that are averaged over the whole three month period.

“So it’s a little bit like odds on a horse race – it’s not saying other outcomes are not possible, but that on balance over the three months we are slightly more likely to have warmer than average conditions.

“It’s not saying hot days, necessarily; it might be milder nights, for instance.”
