When? It snows in winter but not always by far. Last 3 winters we had snow.
20 cms is A LOT and quite unusual. I bought winter tyres this year for the first time in my life.
Winter is November-end of March more or less.
This is a small country, there are weather differences but not huge differences.
Have a look at weatherunderground.com or any other weather site and check out a bit of historical weather.
