It was a foggy start on Monday morning - with commuters in the capital noting the misty October weather.

But never fear - it's supposed to get hot later in the day with temperatures climbing to a maximum of 20C in London.

The fog has even caused some cancellations of flights travelling to London and landing at Heathrow, London City Airport and Gatwick.

After that, the forecast is looking wintry with the weather in the UK set to get distinctly chilly.


BBC London Travel
Heathrow Airport is now seeing delays and cancellations to flights because of fog. If your heading to Heathrow then check with your airline

Alexi Boothman, a forecaster with Meteogroup said: "Clearly, it is a gradual decrease in temperatures from the beginning of the week and it is quite a marked fall in the space of a week with the air mass being turned around."
