Weeks of mild, wet and windy conditions are about to finally give way to a dry but possibly lengthy cold spell.
Temperatures will fall through the start of December amid warnings Britain remains in the firing line for a bitter blast from the east.
Low pressure, responsible for the recent unsettled weather will be kicked into touch by high-pressure building across Europe.
The UK will be straddled by two separate high-pressure ‘anticyclones’–one to the southeast and another creeping in from eastern Europe.
Met Office meteorologist Alex Deakin said: “The models tend to agree we will keep low pressure to the northwest, but a chunky area of high pressure is moving behind those weather fronts to bring drier weather.
“As well as this high developing to the southwest there is also a large high that has been sitting across northern parts of Europe for several days, if not weeks, and the combination of these two highs looks like dominating through the week.
“Which one actually wins will play a big part in the exact flavour of the weather that we see.”
While both will trigger drier conditions, if the easterly high strengthens and pushes further into Britain, a Beast from the East cold snap could be on the cards.
Mr Deakin added: “The position of the high, and which of those highs controls the weather, will determine where our winds come from. It is going to be drier, but it is uncertain which of those highs will dictate.
“As we go into [this] week, we are into the realms of more uncertain conditions, there is the hint of an easterly as we go into the start of December.”
Independent forecasters insist all the ingredients are present for a bitterly cold run up to the Festive season.
While a Beast from the East attack similar to that of late winter 2018 is not certain, experts are still warning something similar could be in the pipeline.
Jim Dale, meteorologist for British Weather Services, said: “As things stand, we are looking at the same weather patterns from a few days ago continuing to build, suggesting high pressure over Europe could encroach towards the UK bringing an easterly cold snap.
“This is not yet a Beast from the East, but the beast is continuing to eye us up and we should be prepared for the prospect of a very cold spell. At the moment, this is looking likely after the first week of December.”
As winter draws nearer, Bookies are scratching their heads over whether the rain or snow will win out.
Ladbrokes is offering 7-4 from 3-1 on the wettest December ever with 6-4 on a White Christmas.
Spokeswoman Nicola McGeady said: “Brits must brace themselves for more bad weather, with the odds suggesting we could be in for a month of record-breaking rain.”
However, current weather models are still favouring snow with flurries likely from the second week of December.
James Madden, forecaster for Exacta Weather, said: “The the computer models are starting to agree that there is a change on the way through the start of December.
“This would suggest a major pattern change to something much more wintry, and this is now looking all but set in stone for taking grip through early December.”
