Snow could fall in parts of south west England this week with temperatures set to plummet over the coming days, according to forecasters.

The Met Office said the country will become colder, cloudier and more unsettled from Monday, bringing the risk of wintry weather in the middle of the week.

Alex Burkill, a Met Office forecaster, said: “Wednesday will be the most extreme in terms of wintry weather, as a cold stream of air will start to push southwards bringing unpredictable wet and windy conditions, even snow or sleet.

“It will be markedly colder than we’ve just seen, daytime temperatures falling by half, and some areas will even struggle to hit 8C (46.4F), which will signify the biggest change in conditions.”

Snow in the south west predicted

The wintery conditions are set to arrive after many areas basked in glorious sunshine with highs of 20C (68F) this week.

Burkill said: “This wintry weather could push into southern areas of England and Wales, which isn’t unusual, it is normal to have colder weather in April, but it’s far from the sunny, warm days seen last week.”

Heading towards midweek, cloud will become more widespread with an increased chance of showers or rain and perhaps even some snow in places.

According to the Met office forecast, Thursday will start to feel colder and windier as temperatures drop with unsettled conditions being likely.

The weather will be windier than previous days, feeling widely cold and becoming increasingly unsettled, with a mixture of rain, sleet and snow towards the southwest and periods of snow at lower levels possible.
