Brits should be prepared to 'get their ice scrapers out' and prepare for frost to cover their car windscreens this week, say forecasters.
Temperatures are expected to drop below freezing in many rural parts of the north on Thursday night before plummeting further to -2C on Friday, according to a new Met Office weather graph.
Southern areas will meanwhile need to brace for chilly nights in the low single figures, as a November chill finally arrives following an unseasonably warm spell.
Warning motorists of the freezing temperatures ahead, a tweet from the Met Office said: "Some of us may need our ice scrapers in the next few days as temperatures dip close to freezing".
In the meantime, people living in coastal areas are likely to see yet more wet and windy weather on Thursday morning, although conditions are not likely to reach the extremes seen earlier this week.
Thunder may come to areas in the south west of England, according to the Met Office forecast, with rain elsewhere filtering out throughout the day.
A number of advisories for flooding also remain in place across the UK.
The majority of these come north of border, where the Scottish Environmental Protection Agency have handed down 15 flood warnings and 12 less serious flood alerts.
A warning means local residents should be prepared for flooding to affect roads, businesses and potentially properties in areas surrounding rivers.
