Watch: Met Éireann forecasts Artic cold weather with snow to plunge down over Ireland

Met Éireann has issued a Weather Advisory for weather that is set to push frigid Arctic conditions that will include snow and other wintry air.

After a mild autumn, the forecaster issued the Advisor for a week-long cold snap from Saturday, November 23. Met Éireann says in a commentary that the weather is set to become significantly colder.

It advises that wintry weather will dominate across the country from Monday onwards and throughout much of next week with frost, ice and showers, most widespread in the north and parts of the west.

The forecast is uncertain for Sunday night into Monday as a low-pressure system tracks over/near Ireland however, persistent rain is expected over much of the country, heaviest over Ulster with the possibility of some sleet and snow on Monday.

The main impacts from Tuesday to Friday will be hazardous ground conditions due to frost and ice with cold day and night-time temperatures. People are also advised to expect poor visibility in any wintry showers.

Met Éireann’s Deputy Head of Forecasting Liz Coleman, elaborated.

“After an unusually mild start to November, people are going to get quite a shock as the temperatures plummet next week, which is why we have issued an Advisory for Ireland.

"Details are uncertain with the exact track of a low-pressure system on Sunday night and during Monday, but at present, some heavy and persistent rain is expected in the west and north with the possibility of some sleet and snow over parts of Ulster on Monday. Met Éireann will be monitoring this situation closely over the weekend.

“However, there is a high degree of certainty that by next Tuesday it is going to turn much colder as an Arctic airmass sinks over the country from the north. Daytime temperatures will often range around 2 to 6 degrees with night-time temperatures widely falling below freezing, bringing widespread frost and ice. The northerly airflow will also bring showers of sleet and snow, these most frequent over the northern half of the country but there is potential for some showers to reach further south. These conditions will bring some hazardous travelling conditions, travel disruptions and poor visibility.

"The extent of the wintry showers in terms of snow is still unclear, but we will have more information as Met Éireann’ s high resolution model comes into play, which provides forecast information two days ahead,

"The cold northerly airmass looks set to linger over Ireland until next Friday at least, but possibly into next weekend too, although uncertainty increases after Friday, November 22," she explained.

Met Éireann advised people to stay up-to date with the forecast and the warnings on www.met.ie the Met Éireann app or Met Éireann socials @meteireann.

It also advises people to follow recommendations before, during and after severe weather on the Be Winter Ready website.

Met Éireann says Weather Advisories are issued up to about a week ahead to provide early information on potential hazardous weather. It says they may be used when a sum of weather elements acting together create a significant hazard.

Met Éireann adds that the issue of Weather Warnings and Weather Advisories is at all times down to the judgement of the Met Éireann Meteorologists/Forecasters.
