A weather warning has been issued for every county in the Republic after sleet and snow led to travel disruption in some parts.
Met Éireann said cold temperatures could mean ice develops on untreated surfaces, leading to hazardous travelling conditions.
A status yellow ice warning will be in effect from 6pm on Friday until 9am on Saturday
The Met Office said “Some slushy accumulations of 1-2cm are possible to sea level this morning,” a spokesperson for the Met Office said.
“Some places above 100m altitude could see 2-5cm, and a few higher spots could perhaps see as much as 8cm of snow before conditions improve this afternoon,” they added.
The day is expected to start out cloudy before becoming drier and sunnier through the morning, with a maximum temperature of 6C.
This evening is predicted to be largely dry, with a few showers in the west.
With snow on higher ground and a low of just 1C, these showers will grow more common in the early hours of the day.
Looking ahead to the weekend, Saturday is expected to be chilly and overcast with sporadic showers, while Sunday may see a few showers.
Two schools - Jones Memorial Primary School in Mullylogan, Co. Fermanagh and St. Joseph’s College in Enniskillen, Co. Fermanagh - are closed for the day.
