Snow clearance work at Laois County Council in Portlaoise.
Met Éireann has snow in the weather forecast for Ireland the first time this winter.
A change in the jet stream's weather patterns has caused the forecaster to predict cold weather with wintry showers of hail, sleet and snow for parts.
The second half of the week to come looks to present the highest risk of snow caused by a blocking high over Scandinavia that will reduce the impact of milder Atlantic weather. MORE DETAILS BELOW AUDIO.
National Forecast issued at 8.23 am on November 25 by Met Éireann.
Saturday: Fine and frosty to begin for many with icy patches and some mist in places. A little less cold in the west and south with the odd light shower. Sunny spells will develop in many areas, but it will turn cloudier from the Atlantic in the afternoon with rain developing near west and southwest coasts towards evening. Chilly, with afternoon highs of 5 to 8 degrees generally, but again, remaining milder in the southwest. Light variable winds will become light or moderate southeasterly as the day goes on.
Clear spells in the north and northeast at first at night with some frost and fog patches and lowest temperatures here of 0 to 4 degrees. However, less cold elsewhere, as outbreaks of rain and drizzle becomes widespread from the Atlantic, and it will turn milder everywhere by morning in a light to moderate south to southeasterly wind. Good dry spells will develop in the west later.
Sunday: A cloudy morning with outbreaks of rain and drizzle in the east, and scattered showers elsewhere. Some sunny spells developing in the afternoon with further scattered showers. A touch milder too with highs of 7 to 10 degrees with light to moderate southerly winds becoming west to southwest or variable.
