At the moment, the outlook for tomorrow is good with conditions expected to improve somewhat. Temperatures are set to rise slightly, with highs of four to eight degrees Celsius.

"Frost will clear tomorrow morning and cloud will increase with a band of rain pushing east across the country during the day. The rain may be of sleet and snow over high ground - especially in the north".

As previously mentioned, this warning applies to the entire country and it's important to be aware of the potential dangers involved with this intense period of cold weather. Be careful out there folks.
