A few useful links I’ve come across for weather related stuff in Dublin.
Irish Met Office is a reasonable site.
The HIRLAM model is very accurate at predicting where and when snow will fall within a 24 hr period. Click on ‘Nedbor’
Watch passenger planes depart from/arrive at Dublin airport here. Excellent radar featuring flight info.
Numerous cancellations and delays at Dublin Airport. Listen in to the air traffic control tower.
