Beast from the East snow scene in Laois
Widespread snow is not on Met Éireann's latest forecast but there will be wintry showers and sub-zero temperatures with a new weather warning issued for snow, ice and wind along the west coast.
The forecaster says the summary outlook if for it to remain "very cold with frost and ice" through the weekend. It says there will be some wintry showers, but overall a lot of bright winter sunshine.
Donegal, Sligo, Leitrim, Mayo and Sligo were issued with new snow-ice warnings on Thursday morning. The forecaster has also issued wind weather warnings for all counties from Cork to Donegal on the Atlantic coast for Friday. WARNING DETAILS HERE.
However, the forecaster issued a Weather Advisory on Tuesday, December 1. It warns cold weather for the rest of the week with sharp to severe frosts and icy stretches with some wintry showers too. It is in force from 4 pm on Wednesday, December 2 to midnight Friday, December 4.
Carlow Weather's Alan O'Reilly expects something similar and explained why. He says charts show Atlantic ridge with Jet Stream dropping south and cold air plunging down from the north. He expects a low system on Friday to bring some wintry showers but mainly on high ground. MORE FORECAST DETAILS FOR THE WEEK AHEAD BELOW TWEETS.

Mayo and other north-western and western counties. More information here: https://t.co/Xg3aMJlyuS pic.twitter.com/HoQ9Ydx2LX— Met Éireann (@MetEireann) December 3, 2020
Interesting to see how the Jet Stream is forecast to move over the coming days. We are currently South of the Jet but by Wednesday we are North of it as cold air pushes down over us. pic.twitter.com/dMo2obMMRY— Carlow Weather (@CarlowWeather) November 30, 2020
An interesting setup in the weather this week. Charts show Atlantic ridge with Jet Stream dropping South and cold air plunging down from North. Low system on Friday could see some wintry showers but mainly on high ground.
