UK storm forecast: Cyclone to trigger cold plunge with week of wind and rain | Weather | New

A ‘secondary’ cyclone spawned by the deep low pressure system will sweep across Britain as temperatures drop. As Scotland faces early snowfall this weekend, forecasters are warning of a national threat of heavy rain.

Torrential downpours threaten flooding in parts of the country as strong winds criss-cross the country.

Jim Dale, meteorologist for the UK Meteorological Service, said: “A low pressure system remains north of Scotland towards the end of the week, but a front entering the country will bring cold air behind it, we therefore, we are looking at a potential cold dip at the end of the week.

“A secondary low pressure system, which is a depression detached from the first, is coming in next weekend, and there’s cold northern air associated with that.

“This week is going to be generally unsettled, with more chance of heavy rain, and there will be an additional risk of strong winds.”

It comes as experts warn Britain could be in line for a particularly savage winter with prolonged spells of cold and snow.

A La Nina cooling of the eastern Pacific combined with building high pressure and sudden stratospheric warming potential, the engine of the 2018 beast from the east, will lead to the cold.

The Met Office said ‘global weather patterns’ will have a ripple effect on UK weather this winter.

Chief Meteorologist Paul Davies said: “The long-term outlook is determined by global weather patterns and while these influences, for example, suggest a higher than usual likelihood of a mild winter, that would not rule out not cold snaps, or even a cold winter.

“These scenarios would simply be less likely based on the information available at the time the forecast is made. It is therefore also important to review our regular monthly updates of the long-term outlook.
Independent forecasters agree early signals suggest the UK is heading for a cold snap.

Freezing temperatures and snow could arrive before mid-October, setting the tone for a numbing fall.

James Madden, forecaster for Exacta Weather, said: “There is potential for a cold winter spell in late October and early next month.

“It will provide a contrast to the warmer weather we have experienced at this time of year in previous years.”

The unstable weather over the next few days will be driven by an active jet stream passing over the UK.

The fast ribbon of air high in the atmosphere, which has split into two distinct arms, will help direct stormy weather across the country.

After an early deluge started the week, northern regions will fall into the main line of fire with a more stable picture for the south.

Stormy conditions will intensify across the country towards the middle of the week as cold winds blow in from the north.

Met Office meteorologist Tom Morgan said: “Monday morning the picture will improve with plenty of sunshine for many parts of KK, some more scattered cloud in the north and some scattered showers.

“For the most part it’s a nice sunny picture in the afternoon, but the temperatures will be down a bit from the weekend.

“There will be a cooler north-westerly breeze for the most part, so temperatures will be down a bit from the weekend, especially if you factor in that northerly wind.”

Weather models reveal temperatures dropping to freezing point in northern Britain next weekend with single-digit lows more widely.

Mr. Dale, author of Weather Or Not? said: ‘It’s going to be colder, although with the high winds there’s less chance of frost.

“But there could be a flurry of snow on the high ground in Scotland.”
