Snow on the Domed City: Science Fiction

Snow fell on the domed city, and at first everybody loved it. They could look up, and see snowbanks climbing up the sides, spreading strange patterns of crystals across the dome edges, anywhere that a little abrasion had made the dome less than egg-perfectly smooth. The snow kept falling. When the snow started to arc over the top of the dome, warnings were put out so that people knew not to panic. The emergency reserve lights, in addition to regular night lighting, would be used, and the snowstorm must surely pass soon. They were warned of the signs of claustrophobia or light-deprivation derangement, and they were told to report to the nearest headshrinker at the first signs, to avoid problems--

Inspiration: Could it be...the over two feet of snow outside and still falling?
Story Potential: Low, but it's an interesting setting.
Notes: I wanted to do something with snow, but fantasy snow-type settings are really, really overdone. This is a bit different. I like it, though I don't think it developed into anything as I did this, which is unfortunate.
