WRAP up warm as it's about to get chilly.
The first sharp cold snap of the winter is set to last for the next few days.
A bitter start to the week will eventually give way to more wet conditions in the middle section, according to Met Eireann.
Today, the cold and frosty conditions will lift quickly, with some hazy sunshine arriving as it starts to turn dry and bright in the east. However, rain will spread westwards across the country throughout the day.
Tonight is set to be very cold again, with frost in the north and west, though temperatures will hover at between three and five degrees elsewhere.
Tomorrow's weather is set to be showery at times in Dublin, with highest temperatures between just five and eight degrees and some light winds.
Tomorrow night is also set to be very cold and frosty, with temperatures below freezing in many places and a risk of icy patches on the roads.
Wednesday will stay mostly dry but with little or no wind, according to a Met Eireann forecaster.
The weather is set to change on Thursday and the eastern seaboard will stay mainly dry throughout the day, with milder temperatures.
Friday is likely to see rain, sometimes heavy, and it will be another mild and breezy day.
Changeable and unsettled weather is expected for the weekend with night-time temperatures back below freezing again.
