Forecasters are warning the UK to brace itself for another bitterly cold night as sub-zero temperatures take grip, with an Arctic blast set to sweep the country over the weekend. Temperatures will fall as low as -2 or -3C in places such as Newcastle overnight, with the mercury struggling to get above freezing in most parts. Over the weekend there will be strong winds bringing an Arctic blast from the north, according to Met Office senior forecaster Tom Tobler. Saturday night will also be extremely cold with widespread frost and snow showers in Scotland and eastern areas of England. Strong winds of up to 60mph are predicted in north west Scotland, meaning blizzard conditions are likely, experts said.
