National Outlook
Overview: Becoming colder for the coming days as an arctic airmass moves down over the country on Tuesday night. While there'll be a good lot of dry, bright weather, there'll be showers too, especially in the north and parts of the west, and some will fall as sleet or hail, with some snow showers too, especially over northern hills. Frost and ice will become fairly widespread for a couple of nights. Turning less cold at the end of the week and for next weekend, but more unsettled.
Tuesday night: A cold night with scattered showers becoming more confined to parts of the north and northwest, with a few drifting into some western parts too at times. Elsewhere, it'll become mostly dry with long clear spells. Some of those showers, especially further north, will turn increasingly wintry, falling as or sleet, with some snow too, especially over higher ground. Rather windy, especially early in the night, with moderate to fresh and gusty northerly winds, stronger along exposed coasts, but the winds will tend to moderate overnight, away from those exposed coasts. Lowest temperatures of -1 to 3 degrees with some frost and ice, especially in sheltered parts.
Wednesday: Wednesday will be a cold day with sunshine and scattered showers, most of those showers in Ulster, Connacht and parts of west Munster, but some possibly drifting into north Leinster too. Some of the showers will fall as sleet and hail, with some of snow too, especially over higher ground in the north and northwest, where some generally modest accumulations can be expected. Highest temperatures of 4 to 7 degrees, and feeling even colder with an added wind chill factor from moderate to fresh north to northwest winds, stronger near exposed coasts.
Wednesday night: Wednesday night will bring further scattered showers, mainly in the north and northwest, some wintry, though the showers will become more isolated overnight. Elsewhere it'll be mainly dry with long clear spells. Lowest temperatures of -2 to +3 degrees, coldest in the east and south, with a fairly widespread frost and some icy conditions developing. The moderate to fresh north to northwest winds will gradually ease mostly moderate overnight.

Thursday night: Thursday night will be cold with mostly clear skies at first, but with cloud increasing from the west overnight. Lowest temperatures of -3 to +2 degrees, with a fairly widespread frost and some icy conditions. Winds will just be light and variable for a time, becoming southwesterly, and increasing moderate to fresh along parts of the west coast later on.
Friday: Dry to begin in all areas, and while it could stay dry in the east and southeast for daylight hours, rain will gradually spread from the northwest through the day. Southerly winds will freshen too and will bring in milder air from the Atlantic with the rain. Highest temperatures of 6 to 11 degrees.
Friday night: Outbreaks of rain for a time, will clear southeastwards, with some scattered showers to follow. Lowest temperatures of 3 to 8 degrees, in moderate to fresh southerly winds, veering southwest and easing.
