Replying to Craziest weather phenominon ever.

Okay so I've been meaning to ask some Tahoe locals about this for a while. Last March in Tahoe during the last big storm of the year, it snow at like 34 degrees with really wet heavy snow. The next morning I went skiing again and that same snow had become extremely dry light snow overnight. Now in Idaho where I hail from in this same situation the colder temperatures of the night would have frozen the wet snow pretty hard or at least left it with a terrible breakable crust on top. So what the hell happened in Tahoe. One of the locals told me it was because of the inversion. That some how it caused the water in the snow to be drawn out. Somebody please explain this to me because by all of my previous experience wht happened it literally impossible.
