snow confusing

I'm always excited by the first snowfall of the year and, according to the weather reporters, we're going to have some on Saturday. What I find confusing, or maybe just amusing, are the variety of possibilities concerning this anticipated snow. Will we have two inches or three inches or will it all turn to rain or will it just kind of disappear before it hits the ground, or my balcony for that matter? I've heard all of these possibilities predicted.  Now this raises another question.  What do I do with snow that piles up on my balcony? Do I sweep it off (I didn't bring a snow shovel with me) and trust it won't hit someone below, or just let it pile up, or build a snow fort against the railing? Or, maybe, there will be enough to build a snowman? I suspect it won't be a problem this weekend but who knows what might come.
