Sun is getting strong but in all could see some lying snow much of the day in places that get maybe more than 5 cm and is a bit sheltered .An area with a good coating will in itself help to keep the temp down.
The precipitation falling during the night time period does help but looking further into the ARPEGE model, DPs are generally a little above 0c (a few areas showing 0c), temperatures are almost all above 0c too. As it stands, I've a feeling that this event will be on the wrong side of marginal for nearly everyone.
Last weekends event showed a lot more potential when the event was less than 36 hours away with cross model agreement between three different models that a decent fall of snow was likely for a large part of Ireland. This time, there's just not enough support being shown.
Let's see what the various models show tomorrow.
