Wrap up warm this weekend: temperatures in the capital are about to plummet, as a mass of Arctic air moves across the UK.
Temperatures will stay in the low double figures tomorrow, before dropping to eight degrees Celsius on Sunday, the Met Office said.
On Monday, the mercury will fall to seven degrees, before the temperature rises to 11 degrees on Tuesday, Wednesday and Thursday.
The chilly temperatures will be caused by a mass of Arctic Maritime Air, which will lead to bright, clear skies on Sunday and Monday, although it's likely to be breezy.
Saturday will be a different story, with clouds bringing rain for some southern parts of the UK, the Met Office warned.
