The UK is expected to be battered with strong winds and thunder as temperatures drop back to normal November levels.
It comes after unseasonably warm weather over the weekend was replaced with fog in the south-east of England.
Remembrance Sunday was the warmest on record, while dozens of flights were cancelled at Heathrow airport on Monday due to the fog enveloping London.
In a weather update, the Met Office said that the UK could expect unsettled weather over the week.
