Clive Burlton, national forecaster at the Met Office, said: "Tomorrow there will be some showery outbursts, particularly to the east of London. It will be cool and cloudier. It will be the same on Wednesday but with a bit of a breeze. That will move away on Wednesday and on Thursday there will be a brisk breeze. Into Friday there will be some cold about but it will also be quite bright and dry. The weekend should be warm again."
