“It’s going to be a cold and very windy day on Friday. We’ll see north to northwest winds starting to pick up through Thursday night into Friday morning, peaking late Friday afternoon . Gale to strong gale force winds are forecast along north facing coasts, generating large coastal waves and spray overtopping. Strong northerly winds over land in the north and northwest could bring down some trees and power lines with travel distribution possible.
Met Éireann has forecast blustery scattered showers on Friday, which will turn to sleet, mainly parts of the north with snow possible over the hills. Daytime temperatures will be limited to around 4 to 9C, but feeling colder with an added wind chill factor from the brisk northerly winds. Overnight temperatures are expected to fall close to freezing for many areas with frost expected.
It will continue cold through Saturday with winds easing early in the day and long spells of sunshine and while most areas will stay dry, there will be a few showers in the north and towards the west coast.
Although it may feel like winter has arrived, milder conditions will move up over the country through Sunday and for the start of next week bring rain or showers at times but generally frost free nights.
The Met Office in the UK says Arwen will track southwards along the east coast of Scotland on England through Friday and Friday night. It has has issued a yellow wind warning for Northern Ireland through Friday and Saturday.
