Weather alert - Northern Ireland braced for drifting snow, gales and rain
I suspect that flight diversions are possible in the coming hours.
Currently - a deep depression is centred WSW of Ireland while pressure remains very high all across Scandinavia and Northeastern Europe - where record late season cold is occurring. As a result - a very severe S'Ely airflow covers Ireland. As the rainfall associated with this depression tracks northwards, it is becoming slow moving and meeting the colder Arctic sourced air-mass to the Northeast - turning readily to snowfall.
During the coming 48-72 hours - this area of low pressure will gradually decline however even colder Easterly winds will become established - with exceptionally cold air filtering Westwards all across Ireland. At the moment - it looks like some areas of Northern Ireland (high ground especially) could see severe snowfall while into early next week - if current guidance is correct - de-icing and wintry precipitation may be the order of the day!
