Storm front splicing Britain in two will plunge parts of UK into chilly winds as heatwave approaches

A storm front splicing Britain in two will plunge parts of the country into chilly winds while elsewhere bakes in summer’s first heatwave.Temperatures of 30C-plus will roast southern, central and eastern counties in the run up to the weekend.But a colossal cold front swept into Britain by a low-pressure storm cell will plunge the mercury in western and northwestern regions.Met Office meteorologist Alex Burkill said: “There is a front lingering across us, and to the south of this, we could get a bit more hot air coming in from the near Continent, but to the northwest, it is staying fresher.
