More weather records could be broken tomorrow, the Met Office has said, with unseasonably warm conditions set to continue until the end of the month.

Although many areas of England and Wales will experience a chilly start on Tuesday, with patches of frost and fog likely, conditions will be exceptionally warm later on.

"It will be very sunny and very warm," said Alex Burkill, a meteorologist at the Met Office.

"Temperature-wise it will be many degrees above average and in and around London, it may even be warmer than [on Monday]."

Londoners and people in the southeast can expect highs of 21C or 22C on Tuesday, with temperatures a few degrees below that in rural areas and the northeast.

Tuesday will also be a largely dry and clear day across the UK.

Monday was the warmest February day on record, after temperatures hit 20.6C at Trawsgoed in Ceredigion, west Wales, beating the previous record of 19.7C in Greenwich in 1998.

Mr Burkill said the conditions were the result of warm air combining with a period of sunshine across the UK.

Winds from the south and south-east, including from Spain and Africa, are pushing air over a part of Wales that has the greatest "land track", causing it to get gradually warmer, he said.

The further the air travels over higher ground, the more moisture it loses and faster it heats up.

Cooler conditions will arrive on Wednesday, with fog expected in the morning across England and Wales.

"The fog could cause disruption at roads and airports," Mr Burkill said.

"It will be a cloudier day than we've seen of late, with temperatures, on average, hitting 15C or 16C. That is still warmer than average for the time of year."

The weather will become less mild and more unsettled from Thursday, with some heavy showers possible.

Temperatures are likely to drop to 13C or 14C by the end of the week.
