A fresh Status Yellow snow and ice alert was issued by Met Éireann amid further snow and sleet showers overnight due to the polar air mass stalled over Ireland.
The alert, which will remain in place until 11am today, covers Wicklow, Donegal, Leitrim, Mayo and Sligo.
Motorists were warned that snow and ice may pose potentially hazardous driving conditions on higher ground in those five counties as well as inland and northern areas.
Snow showers yesterday hit parts of Mayo, Donegal and Cavan which just last week were enjoying balmy spring temperatures.
Ireland’s wild weather mix saw various parts of the country experience snow, frost, ice, hail stones, sleet, torrential rain showers and even brief spells of sunshine all in the space of just 12 hours.
A heavy frost is again likely in most parts of Ireland today with temperatures set to fall to -1C overnight with a risk of sleet and even snow showers.
It will remain very cold for the next two days with maximum temperatures never rising above 10C – some seven degrees cooler than just last week.
Blustery winds, influenced by a northern air mass over Ireland, will make it feel even colder.
“It will remain very unsettled and cold due to the Polar air mass over the country. Temperatures will remain well below average for April,” forecaster Matthew Martin said.
Next weekend will see a slight recovery in temperatures of up to 11C though it will remain unsettled.
However, the week before Easter is set to offer the best weather of the month with temperatures likely climbing to 13C and many areas enjoying good spells of sunshine.
