Sunday 21 October will be wet for Reigate, with Monday through Tuesday getting unseasonably warm – but probably remaining cloudy and autumnal. Make the most of it because thereafter things get interesting with a HIGH pressure building to the North, LOW pressure drifting into Biscay and feeding COOL air from more easterly and northerly winds blowing across the UK. How quickly this cold air feeds down to Reigate is uncertain but Wednesday onwards looks increasingly cool but dry for the South East.
Update: CANCEL the “dry” bit! The charts below show a big cold polar low drifting down over the East of the UK and North Sea from Iceland and Greenland: this will bring a chilly blast of Arctic air across the UK with snow in Scotland, sleet over Wales and a real taste of winter for the rest of us.
