It's bloody freezing outside and weather warnings have been issued for the whole country.
A status yellow low temperature alert is in place until 11am this morning, with the mercury dipping as low as -3 or -4C.
Donegal has felt the chill before us, though, and the first snow of the winter fell there yesterday.
It was especially heavy on high ground, and local climber Iaian Miller got in touch to share these stunning pics of Mount Errigal.
Other residents took to social media to share pics of the snow.
