After this Britain is set to swelter in sizzling temperatures, with the mercury climbing as high as 27C in southern parts of the UK, as a new mini heatwave ushers in blue skies and glorious sunshine for the coming week. The warmer weather will offer a marked contrast to the chilly, wintry weather of the past week and will provide the perfect occasion to get the barbecues out. From Sunday onwards temperatures will steadily climb from 20C up to a peak of 27C in London by the middle of the week.

The best of the sunshine will be across parts of England and Wales, where there will be lengthy sunny spells with temperatures getting into the low 20s.

It should feel warm in the gentle breeze, but further north is going to be quite blustery.

As Sunday comes to an end, there will be more wet weather pushing in from the west across northern parts.

After a wet start to the week in the north, there will be a lot of fine weather for a while.

However, with temperatures hotting up towards the end of next week, the weather will start to become more unsettled.

Terry Scholey from netweather.tv said: “Sunday will be similar across much of England and Wales, with the best of the sunshine in the East and South.

“Parts of northern England could also see patchy rain, but elsewhere it continues dry with broken skies in the South.

Last week saw temperatures plunge, as cold weather brought sub-zero temperatures and frosty nights to many UK farms.

The freezing weather has left many maize crops vulnerable to damage, with temperatures reaching as low as -6C.

While maize crops can tolerate temperatures around 0C, anything below freezing will cause crop damage as leaves begin to wilt and die.

From Sunday onwards temperatures will steadily climb from 20C up to a peak of 27C in London (Image: GETTY) Trending During sub-zero temperatures, water within the plant cells freezes, causing the cells to expand which damages cell walls.

On melting, these damaged cells lose liquid, wilt and die, explained John Morgan, farm adviser at the Maize Growers Association.

Mr Morgan said the extent of frost damage to young maize plants was linked to the temperature and growth stage of the plant.
