Heathrow Airport said flights scheduled after 16:00 GMT were most likely to be affected by cancellations because of reduced visibility.
A spokesman said the airfield was fully operational but more than 10% of flights were expected to be cancelled by the end of the day.
He said this was partly because other European airports such as Paris Charles de Gaulle were running reduced schedules.
Passengers are advised to check the status of their flights with their airlines before leaving for the airport.

The situation has eased but Ian Acheson is one passenger who has had to wait for three days for his Friday flight to Las Vegas to take off from Terminal 5.
He spent more six hours waiting on a plane on Friday and was not given accommodation.
On Sunday, he boarded another plane and after five hours of de-icing he was told his flight had been re-scheduled for Monday.
His luggage was not returned.
He said: "There were some very unhappy passengers."
A spokesman for BA said his luggage had now been located and his plane was due to take off later.
Since Friday, more than 500 flights have been cancelled from Heathrow Airport - 111 on Saturday and about 400 on Friday.
Following days of disruption the chief executive of Gatwick Airport, Stewart Wingate, has now written to Transport Secretary Patrick McLoughlin saying that "over-scheduling of flights at Heathrow during the winter period should stop".
He wrote: "I am proposing that for the key winter months of December, January and February, Heathrow declares a level of capacity it can cope with in winter conditions.
"The additional flights then, for those three months, can move to Gatwick and Stansted. As a result there would be better use of the existing capacity at our London airports, safety would be enhanced and passengers will not have to panic every time it snows."
In response, a Heathrow spokesman said it was for the Airports Commission to examine the issue of UK airport capacity.
South West Trains has been operating 80% of its normal service, said managing director Tim Shoveller.
Meanwhile, the number of school closures varies from borough to borough.
Only two schools out of 55 are closed in the borough of Merton in south-west London, while 80% of schools in Enfield, north London, are closed.
Ayfer Orhan, Enfield Council's cabinet member for children and young people, said conditions were "dire" and the safety of children was paramount.
But an Enfield parent speaking to BBC London 94.9 disputed her description of the conditions and called the lack of consistency across boroughs "confusing".
