Heavy rain moving up over the country on Friday night is likely to turn to snow on it's northern and northwestern flank for Saturday as it comes up against much colder air with more favorable variables for snow coming down to low levels.
There is still some uncertainty as to the precise track.
If it's track shifts further southeast more of the country, including South Leinster and Munster are at risk of snow. If the track stays northwest then Ulster and Connaught have high risk of heavy snowfall.
Right now it looks as though Ulster and Connaught are most at risk of heavy and disruptive snowfall.
However, the forecast track of shortwave is still fluid and likely to shift either way over the coming days.
Areas: North Connaught, Ulster, North Leinster (inc Wicklow mtns)
Risk: Heavy snowfall, the apocalypse, Brexit style chaos
Areas: South Leinster, Munster
Risk: Heavy rainfall, localised flooding
Definite disruption risks for some so keep up to date but some entertainment to be had too.
