Temperatures in Edinburgh are set to plummet below freezing as Scotland braces for "thundersnow" later this week.
The Met Office has issued three snow warnings for Thursday, and warned of warm air from the south west colliding with cold winds from the north in the early hours of Friday morning.
This causes the phenomenon known as "thundersnow", in which the formation of towering cumulonimbus clouds produces lightning strikes.

BBC Weather has also issued a yellow warning for snow in Edinburgh specifically, running from 10am up until 4pm on Thursday - as well as a second from 8pm on Thursday to 11am on Friday.
According to BBC, "some roads and railways" are "likely to be affected with longer journey times by road, bus and train services".
An additional yellow ice warning is also in place from 8pm on Thursday to 11am on Friday, during which "frequent sleet, hail and snow showers may lead to some disruption to travel".
It will be a bright clear day in the city on Wednesday but temperatures will fall throughout the day and evening.
By around midnight, it will be -3 degrees Celsius - and it will remain below freezing for the remainder of the night.
Thursday morning will warm up somewhat, but sleet is expected throughout much of the day.
