FRIDAY 22ND NOVEMBER 2024

Friday is looking like a mainly dry day with some wintry showers in the west and northwest early on some potentially wintry. There will also be some bright and sunny spells but cloud will increase through the afternoon and evening.

The latest outlook for Friday night is for a low pressure system to move into the south of Ireland with heavy rainfall pushing northwards, as the rain moves up into parts of Connacht and Ulster there are signals for some snowfall that could give some temporary accumulations for a time on Saturday morning.

SATURDAY 23RD NOVEMBER 2024

The low will continue to move northwards on Saturday morning with the potential for heavy snowfall across Connacht and parts of Ulster for a time during the morning giving accumulations. This will turn back to rain with heavy showers during the afternoon and evening on Saturday. There will also be a potential for some very strong winds on Saturday with models showing a very deep area of low pressure. Some severe and damaging gusts will be possible based on the latest outputs with some coastal flooding also. This has a potential to be a high impact weather event. Details should become more clear over the coming days.

OUTLOOK

There is some uncertainty past Friday as a low pressure system could again try and move in from the Atlantic trying to move milder weather back in. A few models including the Ecmwf has heavy snowfall across the northwest and north Friday into Saturday with rain across the south and as the low clears back to the east and southeast colder air floods back in staying with us until the first week of December. At this stage there is a degree of uncertainty.
