WABASH VALLEY, Ind. (WTWO/WAWV) – Even if you don’t like the snow, it is nice to look at.
But did you know that all snowflakes are not the same? Some say that there are no two snowflakes alike.
Snowflake types fall into five main categories.
Thin plates start to form when the temperature is 25 to 32 degrees.
Needles form at 21 to 25 degrees, hollow columns form at 14 to 21 degrees, stellar Plates form at a frosty 10 to 14 degrees, and Dendrites when the temperature falls between 3 and 10 degrees.
If the temperature drops to 8 below you’ll see stellar plates again. If it is below negative 8, look for hollow columns.
Now you know your snowflakes, but what is graupel?
Well, snow forms, then falls through a layer of supercooled water droplets. The droplets freeze, or rime, onto the snowflakes.
The end result are tiny, white pellets that resemble small hail. Unlike hail, they are soft and crushable.
