It depends on where you go. Italy is a small country but yet it has several different weathers.
If you come to Milan it will probably be around 10 degrees or less, in Venice maybe less, if you go to Sicily it should be 4-5 degrees higher. On late november sometimes it starts to snow in some places...
What i can tell you for sure is that now it is much more warm and it's not raining at all unlike the past years, so maybe this could mean that we will also have a warmer winter.
Last year the snow came on october, this year i really doubt it will snow till december, but...
I'm an Engineer. I'm surely wrong about this!

Whatever you say, whatever you do, you will be always judged by people.
Try not to be one of them.
