National Severe Weather Warning

A weather front moving eastwards across the UK tomorrow is expected to bring rain and snow to eastern parts of the UK. Parts of East Anglia could see particularly disruptive snow through the morning, an Amber National Severe Weather Warning has been issued. Accumulations of 5-10cm are possible within the warning area.

Separate Yellow National Severe Weather Warnings for snow have been issued covering areas from Scotland to parts of the south east of England where snow is also likely to fall. Within the yellow warning area, higher ground even in the south of the UK such as the South Downs could also see notable accumulations.

Upcoming forecast

Steven Ramsdale is a Chief Meteorologist. He said: “A milder air mass will move eastwards across the UK early tomorrow. But when this warmer, more moist air encounters the cold air situated over eastern parts of the UK snow is likely to fall. Whilst the high ground in the north is likely to see the largest accumulations some snow is likely to fall to low levels at times. In fact, parts of east England and East Anglia look most at risk of seeing 1-3 cm with 5-10 cm possible in places.

“The milder air will eventually win out with the initial snow gradually turning to rain. This may also bring some flooding issues following recent wet weather and with snow then melting – though the snow looks to be the greater hazard.”

Week ahead

Following the passage of this weather front, a pattern of Atlantic-dominated weather will become established, bringing moister and warmer air to parts of the UK, with rain dominating, confining snowfall to the highest elevations in the north.

Nick Silkstone, deputy chief meteorologist, said: “During Monday and Tuesday we will see large rainfall totals across the high ground of western Britain. This rainfall combined with snowmelt will lead to a high volume of water moving through river catchments in these regions.”

During Wednesday, an area of low-pressure anchored in the North Sea will establish a northerly air flow coming into the UK, heralding a return to colder conditions, with wintry showers over higher ground.
