As in the other thread I was saying that this will have to be watched very closely and definately needs a dedicated thread at this stage. It looks certain at this stage that large parts of the UK will have some very disruptive snowfall on Tuesday and Ireland is likely to get some even to very low levels.
The models are just firming up on the track of this depression but crucially Ireland is always on the cold side. Inland areas are most likely to see disruptive snowfall from Monday night and it will be exceptionally cold for the time of year on Tuesday with max temperatures of no more then 2 or 3C and sleet and snow too.
This is probrably one of the most classic significant snow evolutions that Ireland can possibly get. The wind direction also means that Eastern coasts will also be at risk. So basically it will be raining up till Monday night quite widely (heavy rain) and then things will get wintry overnight and on Tuesday and disruption is probrably likely Tuesday morning.
