Weather maps indicate snow accumulations in parts of Northern Ireland on Friday. Areas including County Antrim with Belfast, County Tyrone and Londonderry could see snow by 9am.

The ECMWF model shows purple shading over these regions. Belfast and surrounding areas fall within the affected zones. The forecast covers early hours into the morning.

Met Office meteorologist Annie Shuttleworth stated Friday will bring a colder start than previous days. She noted a change in air mass from Thursday night. Winds will be strong with patchy frost in sheltered spots.

Shuttleworth said north-western areas will experience frequent showers. Some showers may fall as snow to around 200 meters elevation. A mix of hail increases risk of ice through Friday and into Saturday morning.

The national service forecast describes conditions as unsettled on Friday. Daytime temperatures will remain in single figures across affected areas.
