The summer of 2015 has already thrown up plenty of rain and hot temperatures.
But the north of Scotland has been warned to expect frost and even snow in the next few days.
A cold band of Arctic air is set to spread across the country.
And the consequence is that temperatures are expected to plummet on Wednesday night and Thursday.
STV's weather presenter, Sean Batty, told us about the likelihood of an autumnal or even winter blast hitting parts of the country.
He said: "There is going to be some sleet and some snow, although it will only be in places like the Nevis Range and the Cairngorms.
"But we are heading into a ridge of low pressure and it will be accompanied by Arctic air.
"That means that there is the risk of frost in Highland glens and it will definitely feel chilly almost everywhere.
"It is unusual at this time of year, but some parts of the Atlantic are the coldest they have ever been, and we are seeing the effects of that.
"It does mean there will be a big drop in temperatures between last week and this one."
