Overall it is set to be an "unsettled" week although the Arctic blast will soon be over as temperatures are expected to climb upwards to the mid-teens from Thursday.
Here is an overview of the weather for the week:
Tuesday, March 14
Frosty or icy at first this morning but generally dry with spells of sunshine developing. However, blustery and possibly wintry showers will move into the west and northwest during the morning, pushing into the east and south in turn during the afternoon. Chance of isolated thunderstorms too. Becoming largely fine later this afternoon as the last of the showers clear the southeast. Highest temperatures of only 5 to 9 degrees (north to south), with an added wind chill factor owing to fresh and gusty northwest winds.
Tonight, frost and ice will set in quickly after dark under clear skies and easing winds. Cold with lowest temperatures of -3 to +1 degrees. Later in the night, rain will develop in the southwest and across western fringes.
Wednesday, March 15
Dry at first across much of the midlands, north and east on Wednesday with frost and ice clearing. Outbreaks of rain elsewhere will soon become widespread, heaviest across Munster and Connacht with spot flooding. Some local sleet or snow is possible for a time across the northern half of the country. Highest afternoon temperatures of 2 to 5 degrees in the north, but ranging 7 to 11 degrees further south, in fresh to strong and gusty south to southeast winds.
Wednesday night, a wet night with heavy falls of rain, leading to spot flooding, though easing off later. Breezy too, in mostly fresh southerly winds. Relatively mild though with lowest temperatures of 7 to 11 degrees.

Another relatively mild night with lows of 8 to 10 degrees.
Friday, March 17 - St. Patrick's Day
