A weather expert has warned people in the South East to "check their heating supplies" as a cold Siberian airmass moves down across the country this weekend.
The high pressure system, which has already brought daytime temperatures down to minus figures across the Baltic states, is set to move westwards towards the UK and Ireland across the weekend where it is set to settle well into next week.
The latest weather models for Sunday and into next week show a high pressure system to the north of Ireland with a low-pressure system to the south. This "unusual" weather set-up is expected to pull cold Arctic air down from the northeast towards Ireland for at least the next five days.
Latest charts rolling out now and they continue to an unusual setup with high pressure to the North and low pressure to the South feeding down much cooler air from the Northeast. This has potential to bring us some much colder air from the weekend into next week. pic.twitter.com/DtqOK3xy4w

Taking to Twitter, Carlow Weather's Alan O'Reilly said the situation modelled by forecasters "has the potential to bring us some much colder air from the weekend into next week."
He continued: "The big picture is becoming clearer but this far out the finer details are still unclear around how cold it will get or how long it will last and what the risk of snow might be.
"Winter is going to start much colder than we have seen in recent years so check your heating supplies."
Met Éireann has also forecasted the Baltic blast, they say "it'll turn colder over the weekend, with rain on Saturday and showers on Sunday."
The national forecaster says the coming days will get progressively colder until at least Wednesday when daytime temperatures will struggle to rise above a chilly 4 degrees Celcius in the South East.
We'll have more to follow on this.
