A Welsh weather forecaster has said there is a 40% chance the sudden stratospheric warming will see temperatures plunge. There have been warnings that the UK could see another Beast from the East after the weather phenomenon happened over the North Pole earlier this month.
The weather condition makes the jet stream "meander" more which in turn can lead to a large area of blocking high pressure over northern Europe. A previous sudden stratospheric warming that lead to the so-called Beast from the East that hit the UK at the start of March 2018 but forecasters says it is still too early to say what the effect will be this year. A similar warming in 2019 didn't bring the same snow.
Rhian Haf said: "The Met Office have been talking about it for quite a while now. It is due to a sudden stratospheric warming really high up in the atmosphere and the westerly winds will change to easterlies. It is not a guarantee but it could bring really cold weather and some snow. At this point it is really hard to tell what will happen. We are thinking there is a 40% chance it could happen at this stage. So by next Monday it could turn much colder and there will be some snow around."
