Temperatures are set to plummet this week, with snow and ice on the way due to what Met Eireann is describing as a "polar low".
Tomorrow will be a very wet day. There'll be widespread heavy rain and some flooding in Leinster and Munster. It'll be just 5 or 6 degrees.
The forecaster says a cold snap is set to hit on Wednesday night, bringing strong winds.
"Wednesday night will turn cold everywhere as temperatures fall to near freezing in the early part of the night, lowest overnight temperatures zero to plus 3 degrees, coldest in the north. The winds will become cyclonic variable in the north as an area of low pressure, called a ""polar low"", tracks over or near the north of the country. To the south of the low pressure centre winds will be strong and gusty from a southwesterly direction, later veering west. There will be showers too, likely to be heavy and falling as snow over the hills and mountains."
Thursday is set to be another cold day with some wintry showers over hills and mountains. Temperatures during the afternoon will range between just 4 or 5 degrees in the north to 7 or 8 degrees in the south.
Temperatures will range between minus 2 and plus 3 degrees on Thursday night with some ice forecast. There'll be showers, turning wintry with snow likely on the Wicklow Mountains.
Friday and Saturday are both set to be cold days. It will be mainly dry with sunny spells on both days. There could be some wintry showers in the west and north.
