As heavy rain comes into contact with the colder air in places across the country, there is a risk that the rain may turn to sleet or wet snow in some elevated locations, according to Midland Weather Channel.
The weather’s channel Cathal Nolan said that there will be some coverings of snow above 350/400-metres.
He outlined that the latest model guidance suggests that persistent heavy rain is likely across parts of Munster, South and East Leinster and southern parts of the Midlands tomorrow (Friday, October 25th).
“Along the south and southeast coasts rainfall totals are likely to reach between 30-50 mm, with weather warnings likely to be issued for flooding in these areas.”
“There will be a very strong upper air temperatures gradient across the country on Friday with values ranging between 5-7 degrees below normal to the northwest and 5-7 degrees above normal to the southeast.”
The worst of the rain and wintry precipitation will, Nolan added, gradually clear the southeast of the country, through Saturday morning, to leave a much cooler air mass for the remainder of the bank holiday weekend, though staying dry and sunny.
Frost and ice
“Frost and ice will be an issue from Friday night onward with ice likely on untreated road surfaces.”
“The colder spell of weather looks set to last until at least the middle of next week with temperatures below average for early November with sub-zero temperatures by night.” the post added.
