Brace yourselves Brits – it’s about to get frosty.
After one of the warmest summers on record, colder air is blowing over from the Arctic. Northern parts of the UK will reportedly plummet all the way down to -4C overnight this week while lows of around 0C are expected in the south. And although there will be sunny skies, the daytime temperatures across the country are predicted to be around 12C.
This morning (Monday, September 22) saw several rural areas hit temperatures below zero. It was -1.7 degrees in the Welsh village of Sennybridge and -1.9C in the Lake District village Shap.

There’s no snow predicted for most of the country at this point but on the weekend, a forecaster at the Met Office warned that ‘the first snow of autumn is due on the highest Scottish mountains’. Mountain Weather Information Service added: ‘It’s unusually cold for the time of year on Scottish mountains, with bitter northerly winds and snow.’
Looking a little further ahead, the Met Office’s long range forecast says that for September 27 to Oct 2 ‘we are likely to see a change from the settled conditions of the previous days to something more unsettled through the coming weekend’. Apparently, this will ‘most likely see a band of rain reaching western areas of the UK on Saturday, then gradually and erratically working its way east across most of, if not all of the country through Sunday’.
