Met Eireann have issued a snow and ice warning for all of Ireland as "hazardous" conditions are expected.
The alert is in place for the entire country from 11pm on Wednesday until noon on Thursday.
It reads: "Blustery squally showers of hail, sleet and snow with icy stretches on untreated surfaces will lead to hazardous driving conditions on Wednesday night and Thursday morning. Some thunder and lightning expected too."
A further Status Yellow wind warning is in place for Clare, Donegal Galway, Leitrim, Mayo and Sligo from 8am until 6pm on Thursday. It reads: "Very strong and gusty west to northwest winds."
Meanwhile temperatures are set to drop as low as -2C overnight, with Thursday bringing a significant "wind chill".
A Met Eireann forecaster said: "Winds continuing strong in the west and north tonight and moderating a bit elsewhere. Chilly with a scattering of snow, sleet and rain showers. Chance of some thunderstorms too with local hail. Lowest temperatures of -2 to +1 degrees. Some frost and ice will set in also, especially in sheltered areas.
"Cold and very windy on Thursday with strong to gale force and gusty west to northwest winds bringing in sunny spells and further scattered wintry showers. A scattering of snow showers and icy stretches during the morning will lead to treacherous conditions in parts. Some thundery showers and hail too, especially in the west and north. Highest temperatures of just 3 to 7 degrees, coldest in the north, with an added wind chill factor.
"Feeling raw on Thursday night in rather brisk northwest winds with some further scattered wintry showers, mainly confined to western and northern coasts overnight. Long clear spells will develop elsewhere. Lowest temperatures of 0 to 4 degrees with frost and possible ice developing later, that's as the winds ease.
"Mostly dry on Friday with good sunny spells and just light southwest breeze. During the afternoon however, cloud will build across much of the western half of the country. The odd spot of drizzle is possible in Atlantic fringes later. Highest temperatures will range 8 to 10 degrees. Little change overnight on Friday, though southerly winds will freshen towards morning. Lowest temperatures of 2 to 7 degrees, coolest across eastern counties."
And the weekend looks set to bring further rain which will be heavy at times, although there will be some sunny spells too.
A forecaster added: "Mostly cloudy and breezy on Saturday with patchy drizzle across southern and western counties. Highest temperatures of 8 to 10 degrees in fresh and gusty southerly winds.
"Rain is expected to move in across the country during Saturday night, turning heavy at times, however a clearance will develop across Atlantic counties later. Lowest temperatures of 2 to 7 degrees, coolest across western counties.
"The last of the overnight rain is likely to clear early on Sunday, leaving a mostly dry day with sunny spells and just light south to southwest breezes. Highest temperatures of 7 to 10 degrees."
