What a difference a week makes! The whole of the UK may have been experiencing the warmest days of the year so far, but this week temperatures are set to plummet so much weather warnings have been issued.
The Met Office has a yellow warning in place for parts of Scotland, and that weather is set to move further south by Thursday.
The yellow warning for Tuesday and Wednesday says: "Wintry showers on Tuesday evening will turn increasingly to snow and hail during the early hours of Wednesday. This will lead to ice forming on untreated surfaces."

It goes on to say that snow accumulations of 1-2 cm are likely above 100 metres elevation and 2-5 cm above 200-300 metres, and adds: "Wintry showers will continue during daylight hours on Wednesday, but additional lying snow will be mostly over higher hills and mountains."
The cold weather is set to move southwards through the course of the week, with forecasts showing that snow could fall on lower ground in the south on Thursday.
BBC forecaster Ben Rich said: "Colder air will be sweeping south was over the next few days and it will turn cold enough for some of us to see some snow.
"The weather front will be making some more progress southwards during Wednesday bringing some rain along it, but also some sleet and some snow. Much of the snow along the weather front will initially be falling over the hills, but we could see some getting down to low levels say across parts of northern England.
"During Wednesday night into Thursday, there could be a covering of snow even down towards the south, especially over the hills, but possibly at low levels. There will be sunny spells and wintry showers into Thursday with a brisk north or northeast wind that is going to feel cold. Temperatures at best between five and 10 degrees so the days are rather chilly as we head through the rest of the week.
"There will be some showers of rain. sleet and snow. Some sunny spells as well but I mentioned the chilly days there will be some cold nights as well, with a widespread frost developing in many areas from midweek onwards."
It is the second year in a row that weather warnings for snow and ice have been issued for the start of April. Last year, the Met Office issues snow warnings for parts of Wales over the Easter weekend, which was the first weekend in April. You can read more about those warnings here.
