There are now three separate weather warnings in place nationwide as temperatures are set to plummet over the next few days.
With a blast of Arctic weather set to hit from tomorrow, Wicklow Weather have now upgraded their warning until Sunday.
The chances of snow in Wicklow is still up in the air, and it will be a nowcast situation from tomorrow evening.
Significant snowfall is forecast for Ulster and Nth Connacht and it will move slowly south and east across the country and some hi res data suggests this may also include thunder-snow event(s) which could lead to brief blizzard like conditions for a time with very low visibility.
“We have seen a slight change in latest data runs which indicates that a more widespread snow event may occur in some areas further south and east tomorrow,
“But this may be fractured in nature so some areas could see lying snow and others just snow showers that do not cause accumulations.
“We continue to stress that people should avoid all upland road networks nationwide with a combination of “severe” wind chill, blizzard conditions and low visibility.”
AA roadwatch are also advising motorists to be careful tomorrow evening and Friday morning as conditions are likely to be treacherous in many places.
People are also asked to check in on elderly neighbours to make sure that they had adequate supplies and heating.
The ISPCA are also asking pet owners to ensure that their animals have adequate dry and sheltered bedding.
The cold snap in not expected to last long, with temperatures set to recover from Monday, but it could be a brief respite as another potentially cold snap could be on its way towards the end of next week.
