Britain looks set to be blasted by a massive snow and rain bomb, and only one major city will escape the weather chaos.

A 742-mile Atlantic storm stretching all the way from Wick in Scotland to Plymouth in the far south east will hammer all parts of the country on January 27, according to new weather maps.

Snow could hit northern areas and wet weather will impact many southern cities.

WXCharts weather maps, prepared using data from Metdesk, show that most of the northern and southern cities will experience unsettled conditions.

The huge band of torrential rain barreling in from the Atlantic stretches right through England and all the way down to countries such as Cornwall and Devon.

However, London may be the only major UK city to escape snow or rain on this date, maps have suggested.

The Met Office has warned of wetter and windier conditions and a "small chance of snowfall" in some areas.

The long-range forecast from January 22-31 reads: "A transition to a rather more changeable and at times unsettled weather pattern is likely to occur during the first few days of this period.

"Outbreaks of rain and freshening winds will probably make inroads from the southwest during Thursday ahead of conditions more widely becoming wetter and windier by next weekend.

"Whilst a milder, wetter and windier scenario is considered most likely, there remains a small chance that colder air from Europe may continue to feed into northern Britain, especially at first, increasing the chance of snowfall here.

"Towards the end of January, further periods of strong winds and heavy rain are likely to move in from the Atlantic.

"Whilst generally mild conditions look to close out the month, some large day to day changes in temperature are possible.”
