Much colder in fact than recent years. 2019 had a pretty cold November but it looks like 2020 is going to see that cold weather arrive a month later. This may raise hopes of a White Christmas but currently mid to late December is looking pretty dry and benign in Ireland.
The early part of December seems to be signalling a slight chance of snow in Ireland. This will have to be kept a close eye on as it is not set in stone.
Temperatures will be in the low single figures so it could well be a sleety mix. Most of December looks like it will be below 10c with little in the way of milder spells. It will also be drier than normal which will help with Christmas shopping.
