Hats off to weather forecasters, as the heavy snowfall predicted across Scotland and parts of the UK were proved on Tuesday as wintry conditions hit the region.
Just after some of the hottest weather Scotland has ever experienced in March, thick blankets of snow lay over Aboyne in Aberdeenshire, when less than 7 days ago inhabitants of the highland town were basking in 23C sunshine.
Seven inches of snow fell in Aviemore overnight on Monday and more snow is expected across Glasgow. Severe weather warnings have also been issued for Grampians, where 10 inches of snow is said to have fallen.
Roads have been closed in the Highlands and around 3,000 people have been left without electricity after a power line was damaged by the snowfall.
Scottish Hydro plans to have all those affected connected by the evening. Temperature are expected to plunge to around -2C in parts of Scotland overnight.
Northern England, Yorkshire and Humber, and the East Midlands are also expected to bear some of the brunt of this week's Arctic blast.
The Met Office has issued a yellow severe weather warning for Wales as well.
Further south, bitter winds and sleet are expected to provide a chill introduction to April.
Motorists have been warned to take care after a seven vehicle pileup on the Newmill and Canthill Road near Shotts, North Lanarkshire.
Satellite pictures from Dundee University show what a difference a week makes.
However Scottish Transport Minister Keith Brown has said not to panic. He told BBC Radio Scotland: "This kind of weather is much more normal for Scotland than the superb weather we have had over the previous days. So we have had, for example, 124 gritters out overnight.
"Because we've not had this kind of weather over previous weeks, it can catch people by surprise and what we're saying is people should listen to the media, take on board any information they've got about the likely length of time to make their journeys and take the appropriate precautions."
