Arctic air from the north is expected to plunge southwards from Scandinavia this week and could blast wintry weather. WXCharts' snow probability models show a 20 to 50 percent chance of snow between a five day period of Thursday, November 19 to Monday, November 23. The charts turn blue in northern regions of the UK, including central Scotland and as far south as Northumberland and Cumbria.
Temperatures are also expected to drop to freezing lows of 0C in central and western Scotland at the end of this week.
The north-east is likely to face a chilly 3C and further south in London, there may be lows of 4C.
The BBC's long-range forecast said that despite a milder start, the rest of November could be hit with a cold snap due to "high pressure shifting to the west of the UK more often and deeper low pressure areas forming over Scandinavia".
The forecast between Saturday, November 14 and Sunday, November 22, said: "Wet weather will especially affect the north and west, heavy and prolonged for a time.
"But this will clear the UK late on Wednesday.
"A change by Friday, as winds swing into the north-west.
"Colder air moving in for a couple of days, so the threat of some frost in the north and some wintry showers.
"More wet weather will sweep east across England and Wales on 21 and 22."

"Deep areas of low pressure frequently passing eastwards between Scotland and Iceland, into Scandinavia, will prevent a sustained period of cold Arctic winds from firmly establishing.
"Nevertheless, we should be wary of a couple of short-lived cold snaps, when winds swing into the north for a few days.
