UK weather maps turn purple as 608-mile wall of snow and rain to engulf nation Forecasters with Metdesk, which produces WXCharts, show a band of snow and rain to move across the UK amid a cold snap, during which temperatures could dip to -7C These striking weather maps show the UK looks set to be blanketed by a massive wall of snow and rain. The country is poised to endure turbulent weather following a huge plunge in temperatures. The UK Health Security Agency (UKHSA) issues its first cold-health alert of the winter. This is because temperatures could plunge to as low as -7C in some places overnight, a contrast from the 14C recorded on Tuesday in Camborne, Cornwall. Now, weather maps, produced by experts at WXCharts indicate that locations from Fort William in Scotland down to Cornwall in England are anticipated to face icy conditions. Communities are to brace for the shivering vortex from Tuesday November 17. Snow is expected across parts of northern and western Scotland, including Fort William, Glasgow and Inverness, and torrential rainfall is likely to batter the rest of the UK. Forecasters say temperatures are projected to plummet to -7C in the vicinity of Fort William. Across other parts of Scotland, including Glasgow, Inverness and Edinburgh, temperatures are anticipated to sit between -3C and -5C, the maps indicate. This comes after the UKHSA's yellow cold health alert for the Northwest of England and West Midlands from 9am on Thursday to midday on Saturday, reports the Express. The agency cautioned that low temperatures can place increased pressure on health and care services and urged people to check on loved ones and neighbours. Temperatures are projected to drop significantly below the seasonal average by Thursday and Friday, bringing widespread frost to many regions of the country. In some sheltered rural spots particularly vulnerable to cold weather, the mercury could tumble to -6C or -7C. Overnight frost is anticipated across numerous areas, especially throughout rural parts of Britain, though these colder spells are predicted to become mostly confined to southern regions as the weekend unfolds. The Met Office's long-range forecast between November 16 and 25 reads: "Following the tail end of the colder, more settled conditions seen over the weekend, a marked transition to more changeable conditions is expected at the start of the period. "This will allow areas of low pressure to move in from the Atlantic and bring bands of rain and periods of windy weather. There will be some brighter, showery spells in-between however, particularly in the north. "Overall, this period is likely to be wetter than average for the majority of the country. And whilst colder conditions will be possible at times, it will often be mild, with temperatures near or a little above average for the time of year."
