The weather in the last 24 hours has been snow joke, with much of the country covered in an icy blanket this morning.
There is a Yellow snow-ice warning in place until Saturday (advisory: do not eat the yellow snow).
Motorists are being warned to be careful on the roads, many of which are icy and untreated.
However, it seems last night's snow showers were only a taste of things to come this week, with conditions set to worse late tonight and into Thursday.
Here's a selection of some snaps and videos which captured the mini-freeze:
