If you're still attempting to warm up after your morning commute, you're not alone. And it doesn't sound like this morning's weather is going to get any milder any time soon.
Met Éireann have issued a Status Yellow weather warning, forecasting snow, wind and ice for most parts of the country over the next 24 hours.
"The showers will turn increasingly wintry with falls of hail and snow – especially in the north, and a few will push further south this evening. Northwest winds will be strong and gust," reads the official website.
"Wintry showers will be widespread overnight and frequent in the north with accumulations of snow over inland parts of Ulster and other northern areas."
"Mainly dry across the south and southwest. Northwest winds will stay strong and gusty. A widespread sharp ground frost will form during clear spells with icy patches forming widely."
And as for tomorrow? Met Éireann warn it will be 'very cold again' on Friday, with a few sunny spells, but with occasional wintry showers of hail, sleet and snow .
There will be further accumulations of snow over northern counties and over high ground elsewhere.
Ladies, time to rebuild the duvet fort.
