Brits are set to enjoy soaring temperatures with highs of 17C as weather forecasters predict the 'first signs of Spring'.
Temperatures are expected to rocket with the mercury set to reach peaks not yet seen since the start of 2021 and the bitter cold of recent months.
After weeks of snow and freezing temperatures, today's predicted highs are well above the UK average maximum temperature for February, which stands at 6.6C (43.9F).
Highs of up to 17C are predicted for Norfolk and Cambridgeshire today with the mercury rising to up to 16C across parts of the South East and central England.
In fact, 17C (62.6F) will eclipse the average maximum temperature for May, which is 14.8C (58.6F) for the UK, and 15.8C (60.4F) for England.
While much of Scotland, Northern Ireland and part of North Wales have been braced to expect heavy rain, the rest of the UK has been told to expect mild and often dry conditions.
Met Office spokesman Oli Claydon said: "A few days of milder temperatures are forecast.
"Through the week we're into double figures (in Celsius) for many places, including parts of Scotland.
"It will be a noticeable change from what we've had in recent weeks."
Forecasters, though, have said warmer temperatures will be felt across much of the UK in the coming days, with some places experiencing weather more like May than February.
Despite the warmer climate there are still a string of severe weather warnings in place for rain as well as predictions for flooding.
But it's not all sunshine with parts of North Wales, northern England and Scotland under weather warnings for rain.
The rain is forecast to move down across the UK from Wednesday into Thursday, but is likely to clear by Friday.
More sunshine is predicted for the end of the week, with mild temperatures again reaching up to 15C across the UK.
Mr Claydon said: "It will feel more like Spring, especially in the sunshine."
The mild weather comes three weeks after fresh snowfall and sub-zero temperatures across much of the UK.
Despite the warmer weather there are still yellow weather warnings for rain in place for some parts of the UK.
A rain warning for parts of North Wales is in place until 6pm with flooding of homes and businesses likely, as well as longer journey times for travellers.
In Cumbria forecasters are warning of heavy rain until 8pm with more flooding likely as well as travel chaos.
Elsewhere, amber weather warnings will cease to be in effect from 6am while a yellow warning for rain for parts of Scotland is in place until 11am.
The Environment Agency has also issued nine flood warnings and 63 less severe flood alerts.
