National Outlook

Outlook: We'll see a transition from the cold mainly dry weather from the early days of the week to a mobile milder Atlantic pattern. Low pressure will dominate bringing spells of wet and breezy or indeed windy weather at times.

Dry for most for a time on Tuesday night with some clear spells and with lowest temperatures of -2 to +4 degrees, with some frost and ice, mainly in the midlands, east and north. There's the likelihood of some fog and freezing fog for a time too. It will become milder though from the southwest through the night, as outbreaks of rain gradually extends northeastwards across the country along with freshening south east winds. There might be some sleet on the leading edge of the rainfall, but it will be very short-lived if it occurs at all.

Wednesday then will be a cloudy, rather windy day, with outbreaks of rain which will become heavy at times, especially across parts of Munster and south Leinster, with the likelihood of some spot flooding. Milder though than recently with highest temperatures generally of 7 to 11 degrees, a little lower in Ulster in fresh to strong and gusty southeast winds.

Wednesday night will be mild and rather windy for a time too with further outbreaks of rain, heavy at times, with a chance of spot flooding. It'll become drier from the southwest through the night, with the fresh to strong and gusty southeast winds moderating later. Lowest temperatures of 5 to 9 degrees.

On Thursday another spell of rain will spread across the country from the southwest, with some heavy falls and the ongoing chance of spot flooding. Bright or sunny spells and showers, some heavy, will follow later to most parts. Highest temperatures of 8 to 11 degrees in fresh to strong and gusty southeast winds.

Heavy rain will continue to clear from the north on Thursday night, otherwise there'll be a mix of clear spells and showers, some heavy especially in parts of the south and southwest. Lowest temperatures of 4 to 8 degrees in fresh to strong and gusty southeast winds, veering south to southwesterly.

An area of low pressure will track close to, or over Ireland on Friday, bringing the potential for windy weather with showers or longer spells of rain. Highest temperatures of 7 to 11 degrees.

At this stage, it looks like Friday night will bring a good lot of dry weather with clear spells and well scattered showers. Lowest temperatures of 3 to 7 degrees.

It looks like the weekend will bring further spells of wet and breezy or windy weather with temperatures around average for the time of year.
