A weather event similar to the ‘Beast from the East’ snowstorm of 2018 may be approaching the UK once again. Back in February 2018, the notorious Beast from the East caused temperatures to drastically drop across the UK, leading to significant snowfall in various parts of the country.

This phenomenon, known as sudden stratospheric warming (SSW), can bring about Arctic conditions despite its name. The SSW results from a rapid warming in the stratosphere, between 10km and 50km above the earth’s surface, due to changes in the polar vortex. This warming can trigger the descent of cold air, influencing the jet stream and potentially creating a blocking pattern that traps cold and snow for an extended period.

Meteorologists from the Met Office and Netweather are suggesting that another SSW event may occur around November 25 and 26. However, they believe that the impact might not be as severe as it was in 2018. Forecaster Nick Finnis explains that while the UK could experience colder spells and wintry conditions later this month and into December if SSW happens, there are no guarantees of prolonged cold weather.

Before the possible SSW event later this month, there is a chance of snow in the UK next week, particularly in northern regions. The forecast includes predictions of rain, hill snow, icy stretches, and overnight frosts. The BBC Weather forecast indicates showery rain spreading south-eastwards on Tuesday, with wintry conditions in northern hills overnight. Wednesday and Thursday are expected to be cold days, with some wintry showers along coastal areas.
