Weird Looking Snow

On Friday, Jan. 26/01 at about 11:10 am it started lightly snowing, bit of a wind. Looking at the snow fall on my black nylon purse I was surprised to see that every "flake" looked the same and was straight and the size and shape of this dash - ,was white like snow but no snow I'd ever seen. After 5 to 6 seconds this linear snow would "melt" but no water was seen in it's place. Does this snow sound unusual to anyone else besides me? It snowed yesterday, but the flakes were normal looking. |

Sounds like maybe it was sublimating, going from solid directly to a vapor.
Did it look like this?

By growing snow crystals in the laboratory under controlled conditions, one finds that snow crystals grow in different forms depending mainly on the temperature and supersaturation level during growth. This is shown in a "morphology diagram," which gives the crystal shape under different conditions

It was white and had perfectly straight edges. Thanks for the snow crystals link. |
