About snowing, it has snowed in my place for years but this year it's really not happening ... What do you think about this?

Although global human impact (global warming) is not to be ignored, this is mainly because of the El Nino in the central and eastern equatorial Pacific Ocean.

If you're in the Eastern USA, its messing with the jet stream the high/low pressure ridges, causing the cold front to not be within the Northeastern USA area this year.

If you're in other areas far enough I don't know, global warming?

Well winter just started on Monday so wait until January and maybe you will be lucky.
