It's time to dust off your warmest jackets and scarves as forecasters say "winter is finally here" as temperatures dropped by up to 18C in the space of two days.
Last weekend began with a surprisingly mild Halloween, with temperatures reaching as high as 19.4C in Dublin – but last night they plummeted as low as 1C in some areas.
Met Eireann forecaster Joan Blackburn says the chilly conditions will continue for the rest of the week. Ms Blackburn admitted we can’t win when it comes to weather conditions.
“Winter is here, in so far as temperatures for the next week or so will be more like normal for this time of year.
“It will be cold today. There will be a lot of showers about, and there will be rain and hail showers in places.
“Tomorrow will be drier and brighter, and there’ll be less of a wind, so it won’t feel as cold. It looks like milder, wet weather coming in late tomorrow night and persisting through Thursday and into Friday.
"It’s up and down, it’s cool and mild, but we won’t be seeing last Friday’s temperatures this week. It won’t be viscously cold or anything, it’s just cold.”
She said the brighter, showery days are going to be cold, and the wet days will get the higher temperatures.
Temperatures will remain relatively unchanged throughout the next couple of days, ranging from 8C to 11C during daylight hours.
But those hoping to get a reprieve at the weekend will be disappointed.
“On Thursday, temperatures could rise from between 12C to 14C, but it’s wet. Friday is a little bit cooler, with highest temperatures of 12C, and it will be similar over the weekend. There will be some frost cover each night, but not very widespread.”
However, Ms Blackburn insisted that despite the colder weather, November was still classified as “late autumn” and winter was technically a month away.
Forecasters from Exacta Weather earlier predicted that Ireland was in for one of its coldest winters ever.
