Thundersnow to freeze UK as weather forecast warns temperatures will plummet tomorrow

THUNDERSNOW could sweep into Britain this weekend with temperatures plummeting by 20C as an Arctic chill whips through the country.

Freezing air is set to blow through the UK tomorrow as the mercury tumbles down to -5C – quite the drop from the balmy top temperature recorded yesterday of 19.7C .

Some forecasters think the combination of snow and the arrival of wintry showers could cause some dramatic weather – in the form of thundersnow.

Brian Gaze, director and forecaster for the Weather Outlook told The Sun Online: “I would expect the showers to bring a wintry mix, therefore rain, hail, sleet and snow are all possible, as is thunder during the heavier ones.”

Met Office Chief Meteorologist, Laura Paterson, said: “It will feel very cold this weekend, with strong winds bringing heavy showers to many parts.

“Northern facing coastal areas will see the most frequent showers, whilst elsewhere will see more in the way of sunshine.

“These showers could contain hail, and turn to snow on the high ground, mainly Scotland, Northern Ireland and perhaps northern England.”

Dr Michael de Villiers, senior meteorologist for the Weather Company, told The Sun Online: “Rain showers are expected mainly in the north and southward along west and east coasts, while snow is expected on the mountains of Scotland and higher altitudes of the Pennines and light snow at times for Snowdonia. Light snow, or sleet, can reach lower levels at times in the north.

“Brief rumbles of thunder may be heard with rain showers at times (with the attendant risk of small hail) on Friday along the England west and east coasts and Wales coast and in the south on Saturday along the Wales coast and Devon and the east coast of south England.”

Piers Corbyn, forecaster for WeatherAction, told the Daily Star: “Unsettled weather over the next couple of days will clash with the cold snap and there will be some thundery outbreaks.

“Where this happens with wintry showers we could even get a risk of thundersnow.”
