The highest temperatures will be around 10 to 12 degrees but will fall to 4 to 6 degrees in the early evening. Met Eireann has warned of an unsettled week ahead with "the Atlantic feeding in rain and showers across Ireland, turning cold and wintry in parts too, before very mild air returns later in the week".
Here is the national outlook:
Monday night
"Very cold in light to moderate northwest to west winds. There will be showers feeding from the northwest and some may fall as sleet or snow in places. Lowest temperatures of -2 to +1 degrees generally.
Tuesday
"Remaining cold on Tuesday with highest temperatures at best, 4 to 8 degrees but in a harsh moderate to fresh northwest wind. There will be a mix of sunny spells and scattering showers, especially early in the day, and there is potential for these showers to fall as sleet or snow, especially over higher ground.
Tuesday night
"Turning very cold under mostly clear skies early in the night, temperatures will rise in the southwest as cloud increases with rain preceded by some sleet or hill snow for a time gradually pushing into the southwest and west towards morning. Lowest temperatures of -3 to +2 degrees, coolest in Ulster with light westerly or variable winds becoming southeasterly and increasing moderate towards morning.
Wednesday
"A cold and wet day is expected on Wednesday with rain tracking up across the country from the southwest, this will be preceded by sleet and possibly some snow in places, especially over the northern half of the county. Highest temperatures of 1 to 4 degrees across the north of the country but milder in the south with afternoon highs of 5 to 9 degrees, as light southeasterly winds freshen through the day.
"It will get milder in the north during the evening.
Wednesday night
"Showery outbreaks of rain will continue overnight, clearing the southwest though by morning. It will turn into a much milder night generally with lows of 5 to 10 degrees, although it may start a little cooler early in the night in the northwest.
Thursday
"After a wet start over much of the country, the outbreaks of rain will clear the north by early afternoon with showers and some sunny spells following from the west. It will be a much milder day overall with highest temperatures 11 to 15 degrees generally in mostly moderate southwest winds.
St Patricks Day
"While a lot can change between now and then, St Patricks day looks to be fairly cloudy and damp, mildest in the southern half of the country with temperatures of 10 to 14 degrees, but more typically 7 to 9 degrees in the northern in light to moderate southeast to east winds."
