Rebel Alliance in Star Trek

If you're referring to snow falling in the on-screen visuals (can't recall much detail as I haven't watched TESB in a while), then couldn't that just be snow getting blown around by the wind?

Wouldn't water that freezes on the ground just turn into ice? Granted, I'm hardly versed in meteorology and the water cycle beyond what I learned in middle school, but my understanding is that snow is a form of precipitation, which by definition requires aerial condensation.

Could the snow be from ice being melted and evaporated by volcanic activity?

I already considered volcanoes or geysers. But in order for volcanoes/geysers to produce enough precipitation to account for whats seen on-screen, the wourld would end up a festering swamp from the HEAT they also produce.
