Macro Snowflake
Whether a snowflake is delicate and ornate, or dense and pellet-like heavily depends on how "rimed" it is. Riming happens when water vapor fills small cavities within the ice crystals, and then overflows, allowing water to pool into droplets.

More info: NASA has produced the first three-dimensional numerical model of melting snowflakes in the atmosphere. Developed by scientist Jussi Leinonen of NASA's Jet Propulsion Laboratory in Pasadena, California, the model provides a better understanding of how snow melts can help scientists recognize the signature in radar signals of heavier, wetter snow -- the kind that breaks power lines and tree limbs -- and could be a step toward improving predictions of this hazard.
