Monday

Bitterly cold on Monday in mostly fresh easterly winds, Met Éireann has said. While many areas will stay dry, some sleet and snow showers will occur too, mainly across north Leinster.

Some bright or sunny spells, but generally cloudy. Highest temperatures of just 1°C to 4°C with an added wind chill factor.

On Monday night, showers of sleet and snow in the east will become more frequent and push further inland. Very cold with clear spells and lowest temperatures of -3°C to 0°C with a widespread sharp frost and icy patches.

Tuesday

Tuesday will continue very cold with further wintry showers of rain, sleet and snow feeding in from the east. They will mainly affect the eastern half of the country, especially coastal counties with moderate snow accumulations in places.

It will be mainly dry further west with just isolated showers. Daytime temperatures of just 1°C to 3°C with fresh easterly winds, strong on southern coasts.

Tuesday night will be very cold with lowest temperatures of -4°C to 0°C with severe frost and ice causing hazardous conditions. Some further showers of sleet and snow in the east.

Wednesday

Wednesday will continue very cold with daytime temperatures only reaching 2°C or 3°C. There will be a good deal of dry weather, though some further wintry showers are likely, especially in north Leinster and east Ulster.

Wednesday night will be cold and frosty in many areas. Rain, sleet and snow will develop in the southwest overnight.

Outlook

Current indications suggest that on Thursday, rain, sleet and snow will move northeastwards over Ireland. It will fall initially as sleet and snow with significant accumulations possible before it turns to rain as milder air moves up from the south.

Daytime temperatures of just 1°C to 4°C. On Thursday night, sleet and snow will continue in Ulster and Leinster, while showers of rain will develop in the west and south.

On Friday it looks like there may be further falls of sleet and snow in parts of north Leinster and Ulster, with showers of rain further south. Eventually the milder air will reach northern areas and the weekend will be less cold with a few showers.
