Britain is set for the warmest day of the year so far with temperatures anticipated to soar as high as 19C on Thursday.
Above average temperatures have been forecast for the first time this year with highs of 18C-19C and 16-17C expected more widely across the country, the Met Office said.
It comes after Kew Gardens saw temperatures of 18.7C; however, its title of warmest day of the year could be stolen on Thursday.
However, it isn't all warm weather as there is a band of cloud and rain in western parts of the country moving east, Met Office meteorologist Honor Criswick said.
'To the east of that, it should be mostly fine,' she added. 'There should be lots of long sunny periods until that rain starts pushing into the east.'
Much of England and Wales are set to experience cloudier weather on Friday as temperatures are expected to crawl to between 11C and 12C.
Meanwhile, Northern Ireland and Scotland are anticipated to enjoy sunshine during the first week of Spring.
Start of Meteorological Spring Brings Mixed Weather
The weekend will be a mix of patchy cloud and some sunshine with highs of between 12C and 13C on Saturday as well as 14C on Sunday, Ms Criswick added.
'It's the first week of meteorological spring so not a bad forecast,' she added.
It comes after the Met Office confirmed February was one of the dullest and wettest on record with it being 23 percent wetter than average across the UK.
In England, there was 70 per cent more rain than usual - with Worcestershire experiencing its wettest February ever recorded.
Met Office Science Manager Dr Amy Doherty said: 'February's mild and notably dull conditions have brought a winter of considerable contrasts to a close.'
'While February itself stood out for its exceptionally low sunshine and above average temperatures, the broader winter picture shows just how varied conditions have been around the UK.'
'Some southern and central areas of the UK experienced persistent rainfall, leading to saturated ground and several areas recording one of their wettest winters on record.'
February Ranked Among the Warmest on Record
'In contrast, parts of northern and western Scotland were markedly drier, which is notable given these areas are typically among the wettest in the UK.'
In terms of temperature, last month was the ninth warmest February on record - with the nights proving to be particularly tepid.
'Notably, 21 counties recorded their highest February minimum temperature on record, highlighting unusually mild nights,' the Met Office explained.
Sunshine was in short supply for much of the UK, thanks to the dominance of cloud-bearing Atlantic systems.
The UK had its fourth dullest February on record, while Wales had its dullest ever February.
'This year, it was eastern Scotland that saw above average rainfall, highlighting an unusual reversal of the pattern normally expected, and demonstrating the strong regional differences that can develop within a season,' Ms Doherty explained.
'Taken together, the winter and February figures highlight the influence of a predominantly Atlantic weather pattern and the pronounced variability that can characterise the UK climate.'
