Met Eireann has confirmed snow tonight in Dublin and around the country as an urgent weather warning is issued for several counties across Ireland.
It will be cold today with the occasional sunny spells which will turn wintry as temperatures roam around the 4C mark.
Tonight will see outbreaks of "rain, sleet or snow" edging in from the northwest leading to potentially poor travelling conditions as the dial drops to -3C.
It comes as a status yellow, low temperature/Ice warning is in place for Connacht, Cavan, Monaghan, Donegal, Longford and Clare until 10am on Wednesday morning.
Met Eireann states: "It will be very cold with temperatures falling to between -2 and -5 degrees, possibly colder locally, with a widespread severe frost. Icy patches may form on untreated surfaces. Freezing temperatures will persist throughout the day on Wednesday.
There will be three days in a row of wintry showers from Wednesday to Friday as temperatures drop sub zero.
But, it will make a drastic change on Sunday when temperatures will pick up again to 8C remaining largely dry for the first time in weeks.
Here's what Met Eireann are forecasting for the next few days:
Thursday: "Mostly cloudy with rain, and sleet clearing southeastwards during the morning. Brighter conditions with sunny spells will develop during the afternoon. It will be another raw day with highest temperatures of just 1 to 3 degrees, in moderate northwesterly breezes. Largely dry and clear apart from the risk of a few wintry shower especially in parts of east Ulster and Leinster. Lows of -2 to +2 degrees with widespread frost and icy patches in moderate northwest winds."
Friday: "Many areas dry on Friday with sunny spells. However, wintry showers may affect mainly eastern and western coasts. Daytime highs of 2 to 4 degrees in moderate northerly breezes. Turning bitterly cold once again under long clear spells with lows of -1 to -5 degrees with a widespread severe frost and icy patches forming in light and variable breezes. Any remaining wintry showers near southeastern coasts will die out overnight. Cloud will thicken over Ulster by morning."
Saturday: "Frost and ice will slowly clear by morning. It will be a cloudier day over the northern half of the country, with showers in the west and north. The best of the brighter weather will be further south and east. In mainly light westerly breezes, highest temperatures of 2 to 5 degrees generally, but a few degrees milder under the thicker cloud and patchy rain in the northwest. Showers will persist along western and northern Atlantic coasts, remaining mostly dry elsewhere with a mix of cloud and clear spells. Lowest temperatures of -2 to + 3 degrees in light westerly or variable breezes allowing for some mist and fog patches to form."
Sunday: "Frost, mist and fog patches will clear through the morning leaving a mix of cloud and bright spells. The risk of showers will continue along northern and western Atlantic coasts, remaining largely dry elsewhere. Less cold in light to westerly breezes with highest temperatures recovering somewhat at 5 to 8 degrees."
Early next week: "Highest risk of showers will be in the north and west with generally drier conditions expected elsewhere. Temperatures look likely to returning closer to average as a mainly light westerly airflow becomes establishing."
