The latest weather maps show that later this month, temperatures in the UK will drop again, bringing the risk of snow after a period of mild weather.

The weather forecast by WXCharts.com said that snow might come back and hit the UK on March 28. The maps issued by the forecaster are showing snow hitting the north of the UK.

Scotland could see up to 8cm of snow, while there are chances England could be hit in the north and north west.

Before this, however, the UK could experience much milder weather starting from this week. Several areas of the UK could see temperatures soar to 19C on Wednesday, and possibly even 20C, in a new weather forecast. Forecasters say a spell of warm and pleasant spring weather is set to develop across much of the country this week, bringing sunny skies and rising temperatures for many.

Dan Harris, chief forecaster at the Met Office, said: “Wednesday looks likely to be the warmest day of the week for many, with high pressure dominant”.

He added: “The warmest spots are likely to be in parts of west Wales and western England, where under sunny skies, 18-19ºC, possibly even 20ºC is on the cards. This is due to the additional boost expected from the passage of east-to-southeast winds over higher ground, known as the Foehn effect.

“There’ll be a big diurnal range this week, which is the difference between the maximum daytime temperature and minimum overnight temperature. Thanks to the clear skies during the day, we’ll see some chilly nights after the warmer days with a few places experiencing air frost.”

Temperatures will cool again towards the seasonal average on Friday, the Met Office also added.

Meteorologists say the boost in temperatures will be helped by east to south-easterly winds moving over higher ground – a phenomenon known as the Foehn effect – which can cause air to warm as it descends on the other side of hills and mountains.

Despite the spring warmth during daylight hours, forecasters have warned nights could remain chilly due to clear skies, creating a large contrast between daytime highs and overnight lows. Some areas may even see air frost.
