SPELLS of 20C warm sunshine will sweep across the UK today – before a fresh Arctic plunge sends temperatures plummeting into the bank holiday weekend.
Patchy light cloud will break up to give long periods of clear blue skies across much of England and Wales on Tuesday, forecasters say.
That will send thermometers soaring to the high-teens – even hitting 20C in central parts, according to the Met Office.
Light winds will also add to the balmy feel across most of the country on Tuesday.
The only exception to the sunny skies will be in western parts – where showers are expected to dominate.
SHOWERS FOR SOME
In Northern Ireland and western parts of Scotland, thicker cloud will linger and cause outbreaks of rain for much of the day.
But even here, temperatures should hold up in the low- to mid-teens.
Pollen levels are also expected to be high in most parts apart from the west – where the risk is moderate.

But conditions are expected to worsen as the week continues and heads into the May bank holiday.
The Met Office says there will be some dry and bright patches as the week progresses.
But Friday should see much colder weather as Arctic air plunges southwards.
It means parts of the north could even see some wintry showers return.
Elsewhere could see widespread frost – and high ground in Scotland could even get a dusting of sleet.
SPANISH PLUME ON THE WAY
But Brits can expect to enjoy higher than average temperatures in the weeks – 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 900-mile-wide 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.”
