The predicted temperatures of 14C by the middle of the week are well above February's average, with 9C the usual average in southern England, which will be a "noticeable shift" after the last fortnight which was below average, Met Office meteorologist Jonathan Vautrey previously said.
According to the Met Office, London is set to see sunny weather on Monday and Tuesday, with temperatures of around 6C with the rest of the week getting steadily warmer until Friday’s highs of 14C.
Mr Morgan said: "We've basically got this battleground taking place over this weekend between cold air across Scandinavia and central Europe, which is affecting eastern parts of the UK, but towards the west is a little bit milder.
"The Atlantic is trying to shift that cold air out of the way, pushing from west to east across the UK, but it's a very slow process and it will take until the middle of the coming week for conditions to turn much milder nationwide.".
Met Office meteorologist Tom Morgan said he does not expect any national records to be broken, but some areas could go 10 days without any sunshine, which is "near record-breaking".
