"Uncertain" weather conditions are set to hit Norfolk later this month due to a once-in-a-250-year weather event.
For the first time since records began in the mid-20th century, the UK has seen three Sudden Stratospheric Warming (SSW) events in one winter with unsettled and uncertain weather on its way.
An SSW is a disruption of the normal airflow to the west from 10km to 50km above the Earth which often causes the jet stream to move bringing adverse weather.
One famously caused the Beast from the East in 2018, forcing hundreds of schools to close and covering Norfolk with snow.

These events vary in nature but have often resulted in colder-than-average temperatures with the two previous events this winter bringing spells of freezing temperatures and wintry showers.
A spokeswoman for the Met Office said: "The impacts of an SSW do not always equate to cold weather, for example, we have only seen intermittent drops in temperature around the two SSW events early this winter and typically around 70pc of events are associated with a cold snap.
"Beyond five days into the future, the chaotic nature of the atmosphere starts to come into play - small events currently over the Atlantic can have potentially significant impacts on our weather in the UK in several days."
