My Samsung Galaxy S does the job. Large graupel falling at 5:03 PM immediately following the front.
For those of you wondering, yes, graupel is fully recyclable. Surely you've heard of the water cycle!
These heavily rimed snow crystals form in strong updrafts, which we certainly had at the leading edge of the surface cold front. I suspect we'll see a transition to big fat aggregates (multiple snowflakes stuck together) soon.
