Met Eireann has confirmed the first few days of Winter will hit in Ireland this week as THREE nights of 0C are promised.
Tuesday, Wednesday and Thursday night will see the mercury drop to a teeth-shattering zero as hail, frost and thunder cause havoc across the country.
Today will be cool and blustery with widespread heavy showers and the risk of hail and isolated thunderstorms.
There will be bright and sunny spells too with highest temperatures of 11C dropping to just 5C with continued hail and thunderstorms through the night.
Here's how the rest of the week is looking with the forecast for those wintry days:
Summary: "High pressure dominating for much of the week so quite dry and settled conditions with light winds. Cool though with some cold nights, frosty in places."
Tuesday night: "Becoming a mostly dry but chilly night as showers largely die out early on but a few may remain in northern areas. Lowest temperatures of 3 to 6 degrees in the northern half of the country where it will be cloudier and 0 to 4 degrees in the southern half in more prolonged clear spells. Light west to northwest breezes will allow mist and fog patches to develop along with some patchy grass frost."
Wednesday: "Mist and fog will gradually clear during the morning to leave a cool and mostly dry day with sunny spells and just a few isolated showers along northern coasts. Highest temperatures of 9 to 11 degrees in light northwesterly or variable breezes."
Wednesday night: "A cold and dry night with lowest temperatures of 0 to 4 degrees generally but a degree or two warmer in parts of the northwest and north. Again, mist and fog will develop in light or near calm conditions and long clear spells with frost forming too."
Thursday: "Mist and fog will be slow to clear and may linger in places throughout the morning. A largely dry and bright day though there is the possibility of some isolated showers over Munster and Ulster. Highest temperatures of 9 to 12 degrees in light variable breezes.
Thursday night: "Another cold and dry night with patches of mist, fog and frost developing. Lowest temperatures of 0 to +4 degrees, coolest in the midlands and in the north, in light southwesterly or variable breezes."
Friday: "Cool and dry for Friday with some good sunshine. Becoming cloudier in southern areas later with patches of light drizzle moving in towards the evening. Highest temperatures of 7 to 11 degrees in light easterly breezes."
Weekend: "Current indications are that the high pressure will drift away with some outbreaks of rain pushing up from the south for the weekend, with temperatures increasing slightly."
