Temperatures across the country are cooling fast, falling into the single figures for the first time since last winter. Weather forecasters expect they will continue to fluctuate and ultimately settle into autumn patterns by mid-October. While the south sees average temperatures, further north will reckon with a piercing cold, and eventually snow.
According to the Met Office, northerners will have to reckon with a wayfaring polar vortex.
The vortex will send wind and rain into the region at first before becoming more widely established.
Snow will follow as the country embraces autumn between late October and early November, the forecasters added.
Weather maps show the first signs of snowfall by October 24.
WXCharts winter overviews pinpoint a light scattering of snow just north of Cardiff, roughly 1cm deep.
Snow showers will also appear further north at the same time, taking to the peaks of Snowdonia.
The same maps show some widespread coverage on Scotland’s east coast around Loch Lomond.
Greg Dewhurst, a senior Met Office meteorologist, said the first snowflakes would meet high ground.
Elevated areas likely to see snow as a months change include more mountainous locations, especially the peaks of Scotland.
Between October 25 and 27, charts show a scattering of snow across the Cairngorms mountain range just north of Dundee.
Forecasts suggest temperatures could also usher in a “white Halloween” on October 31.
But low-lying areas are “unlikely” to see any of this, Mr Dewhurst added.

Meteorologists have blamed the polar vortex for the unseasonal weather.
The vortex is a circulating mass of cold air that primarily sits over the Arctic Circle.
Extreme 155mph winds pin it in place over the region, but a warming stratosphere is slowing it down.
Seasoned forecaster John Hammond told the Sun the increasing temperatures are preventing the expected late October intensification.
The “unusual weakening” could impact British weather from mid-autumn to early winter, with chances of a severe cold increasing.
But the consensus isn’t shared by bookmakers, who have taken the balmy start to October as a sign.
Betting firm Coral has slashed the odds for a “record hot” October this year.
They currently supply 2-1 odds that the month will end with higher than average temperatures, not a gathering chill.
At the same time, the bookmakers predict the temperatures could rise high enough for a similar record-breaking Christmas.
Odds for a record hot Christmas are now at 6-4, down from 3-1.
Coral’s John Hill said: “If the latest odds are anything to go by, we could be set for a sweltering Christmas this year.
“We have slashed the odds on this Christmas Day being the hottest we have ever had, so many may be considering a BBQ for their Christmas dinner this year.”
